“All Business with No Wasted Effort”

Rifle Dynamics’ Interest in the AK

Las Vegas-based Rifle Dynamics (RD) is one of the premier AK gunsmiths in the U.S. Jim Fuller’s Rifle Dynamics is one of the few truly qualified companies that can improve the AK platform beyond its out-of-the-box potential without impacting its “hell and back” reliability, simplicity and ruggedness. Jim has always been impressed and attracted to most Soviet-Block weapons; even though many in the U.S. discounted Soviet arms as inferior tools of the enemy. This led him to intensifying his study of the AK system of operation beginning in the early 1990s. Jim believes the AK is the most dependable fighting rifle ever produced. While it may not be as inherently accurate as other rifles, the AK is still plenty accurate for the job it was designed to do as a combat arm. Rifle Dynamics is an 07FFL/SOT manufacturer which allows for work on machine guns, suppressors, SBRs and SBSs combined with being considered a dealer as well.

The true hallmark of the AK-series of rifles gaining acceptance in the U.S. is the rise of gunsmiths, ammunition manufacturers and aftermarket accessories starting to cater to its clientele. Based on this, Fuller decided to introduce a Rifle Dynamics AK signature line that encompasses many upgrades and modifications over “factory” standard AKs. With so many customers inquiring about Jim’s opinion for a solid, no “frills” AK fighting rifle, he decided to invest in making this type of AK available to customers without having to experience the wait associated with custom projects. These production RD AKs will benefit from years of experience gained from doing improvements on customer-provided rifles and custom orders.

Jim Fuller explains, “We (RD) are doing different production rifles that are basically the same except caliber (7.62×39 and 5.45×39) and stock configurations. All RD models will have our custom front end with Bolten Gas block. The muzzle device will be a Battle Comp AKBC on the 7.62 guns and Battle Comp 2.0 on the 5.45 guns. TAPCO G2 triggers will be used as standard fire control. A Fuller designed rear sight is included as well as a U.S. Palm AK Battle grip. The RD AK production AKs will have an UltiMAK upper rail installed.” Jim goes on with, “There won’t be any other options since these are production rifles. The quality will be what you would expect from one of our (RD) custom builds, but we have to limit options in order to produce them in a timely manner.” The current RD production AKs will be labeled RD700 for 7.62×39 rifles and RD500 for 5.45×39—simple enough.

The RD702 AK

The particular Rifle Dynamics rifle tested is the RD702. The RD702 AK is chambered in 7.62×39 and utilizes the RD AK/M-4 stock adapter to affix a Magpul CTR rear stock. The RD702 AK benefits from a custom front end consisting of a Bolten gas block offered through Venom Tactical. Aesthetically, the RD702 gets your attention immediately with its 14.5-inch barrel with pinned PWS FSC flash hider. Rifle Dynamics is proud of its custom front end work featuring the Bolton Gas Block; this sets apart RD AKs from others. The RD modification removes almost 1 pound off the front of the rifle, moving the center of gravity about 4 inches closer to the body making the RD702 feel very light and more importantly the fastest handling non-SBR-length AK on the market. The RD front end work is complimented by adding an UltiMAK gas tube scope rail. The UltiMAK provides a solid mount point for whatever forward mounted optic you prefer.

The Rifle Dynamics’ RD702 AK features a Fuller Modified Rear Sight unit. Jim reports this is one of his most popular AK modifications in terms of customer feedback. Over the years many have complained about the iron sights on the AK; the Fuller Rear Sight improves this tremendously. The Fuller Sight has the notch widened and corners radiused to a spec that was given to Jim by an Optometrist for maximum efficiency in centering the front post in the rear notch. Both windage and elevation adjustments are made on the front sight. Jim ships the rifle with a long front post expecting elevation adjustment to be fine tuned by filing down the sight and windage adjustments made by turning the front post to whichever side is necessary. The finish on the RD702 AK tested is Norrell’s Moly Resin gray applied over fresh Parkerizing. Rifle Dynamics has found this to be the best finish for a rifle that will take a lot of abuse, heat and lack of cleaning. Jim reports the finish has proven itself many times over in the worst conditions.

There is a tremendous amount of fitting that goes into the Rifle Dynamics’ RD702. Even though a “production” rifle, the RD702 benefits from RD quality control via internal reliability checks, fire control group polished and light planing on the bolt/carrier group and guide rails, combined with exterior surfaces being dehorned where users touch them. Jim takes great pride in the amount of fitting that goes into everything Rifle Dynamics produces. Most owners will not even notice the Rifle Dynamic attention to detail but can take comfort that everything possible has been done to make a Rifle Dynamics’ AK the best fighting rifle available. Even without firing a live round the Rifle Dynamics AK superiority over a standard AK can be detected in the smoothness of the action, trigger pull, quality of re-finish and overall weapon feel. Rifle Dynamics is well-versed in the nuances of the AK platform and can educate even the most diehard AK connoisseur. The RD702 7.62×39 reviewed in this article will retail at $2200.

Evaluation

After a quick verification of 25-yard sight zero, range evaluation commenced with a function test involving firing several magazines in rapid succession at various steel man targets and vehicles that dot Echo Valley Training Center (EVTC) where I do my testing. While not unique, this is a good way to establish a baseline for reliability. Let’s face it: if an AK-type weapon does not have pristine reliability, its major attribute is nullified. I made sure different types of AK-47 magazines were used to verify compatibility with the RD702 AK. Metal and polymer 30-round magazines of various manufacturers performed fine with no issues inserting, removing or feeding the rifle. The U.S. Palm AK-30 polymer-style magazines were the primary magazine used after initial magazine trials. The U.S.-made AK-30 magazine is molded so that disassembly is not possible or warranted. The AK-30 magazines were complimented by the AK Attack Rack. The AK Attack Rack is a low-profile, secure platform for 4-AK magazines and 4-pistol magazines. The AK Attack Rack chest rig can be worn over hard or soft body armor and is built to military specifications out of 500d Cordura nylon for durability and minimal weight.

A more comprehensive 100-yard sight zero confirmation took place after functionality was established. After first using the Fuller modified rear sight found on the RD702, I decided to mount a Trijicon MRO. Many will be more than satisfied with the Fuller rear sight and eschew mounting anything on the rifle choosing a more traditionalist route. I found the UltiMAK rail too tempting and favor the advantages associated with red dot sights. Red dot sights offer the capability to engage multiple targets in rapid sequence compared to open sights. Age may be catching up to me as the single focus plane with the red dot is easier to shoot accurately than coordinating front and rear sights.

The Trijicon MRO (Miniature Rifle Optic) is a sealed miniature reflex sight intended for use on rifles, carbines and shotguns to provide fast target acquisition. The large aperture and tapered light path maximize the viewing area and allow for better situational awareness and fast target engagement—especially from non-standard shooting positions. Combine all this with the ambidextrous brightness controls, sub-flush adjusters, advanced lens coatings and the fully sealed, waterproof, hard-anodized forged 7075-T6 housing, and you have the ultimate mini reflex sight on the market. The MRO’s 2MOA red dot offers the capability to engage multiple targets in rapid sequence compared to open sights, while at same time providing adequate accuracy out to a couple hundred yards on man-sized targets; yards due to the red dot not obscuring the target due to the dot not being that large.

Multiple 7.62×39 loads were tested with the Rifle Dynamics’ RD702 AK such as Hornady, Wolf and Red Army Standard. All of the loads produced approximate 3-inch groups at 100 yards. In all fairness, a magnified optic would have probably produced better accuracy results in lieu of the open sights, especially with the Hornady SST loads. Gilt edge accuracy is not the goal with any Rifle Dynamics’ AK; it is a fighting rifle measured by a different set of parameters.

Other range tests consisted of completing several runs on EVTC’s “Jungle Walk” range. Several ISPC-style man targets and steel silhouettes were engaged from different firing positions. Multiple shots were fired at each target, and a magazine change was mandated before leaving cover. I find testing any rifle in this format helps highlight any strengths or weaknesses in handling or weapon manipulation. The Rifle Dynamics’ RD702 AK handled as well as any rifle I have tested. There is a fundamental reason why AK versions proliferate around the world and now are spreading across the land of its Cold War nemesis. This is due to the AK’s well-earned reputation for ruggedness and reliability.

Rifle Dynamics’ understanding and appreciation of the AK as a fighting rifle translates into the RD702 accentuating these characteristics with no urge to make it into anything else. The UltiMAK rail is a nod to the advantages offered by a red dot optic or by possibly mounting a tactical light without succumbing to the urge to hang items that are not necessary on the forend, ruining handling. The Fuller rear sight is another subtle refinement intended to upgrade the AK platform without hindering its design intent. The honing, polishing and fitting of internals such as trigger mechanism and bolt carrier are done to compliment smoothness of operation, not reduce tolerances to a point that compromises reliability out in the real world. All business with no wasted effort—that sums up the Rifle Dynamics RD702 AK.

Though modified to meet import requirements via sporter stock with no pistol grip, at the heart of the Russian VEPR rifle is an AK operating system. The process to modify the VEPR back into the more familiar AK profile is relatively well known and straight forward process involving moving trigger guard forward to make room for pistol grip, replacing fire control group, and installing AK stock of choice. Krebs Custom takes this a step further – a much larger step. There is a tremendous amount of fitting that goes into the all Krebs Custom AKs. All receive an internal reliability check with a light honing of the bolt/carrier group and guide rails. Krebs Custom has lent its expertise to the KV 13 VEPR rifle in an effort to increase its performance levels. One obvious Krebs’ tweak is the extended length open sight configuration. Krebs Custom provides an integral M16A2 aperture rear sight mounted on the rear of the dust cover with both battle sight and long range apertures that is windage adjustable. The Krebs’ AR-type open sights provides 60% greater sight radius than a standard AK. The AR style sights combined with increased sight radius offered by mounting rear turret on dust cover is far superior to standard AK sights.

Krebs Custom continued with upgrading the KV 13 VEPR by installing a customized KeyMod interface railed forend. The KeyMod rail was designed by VLTOR and now open sourced to the industry. An important KeyMod benefit is it keeps the overall rifle package lighter and more compact. The Krebs Custom Key Mod rail is perfect for adding any suitable optic due to its rock steady nature allowing for no shifting zero once a scope is sighted in. The ability to use forward mounted optics shows the flexibility offered by the Krebs Custom KV 13 modifications.

The Krebs VEPR AK 5.45×39 measures 38 inches long with stock extended and 34 inches when fully collapsed from rear buttstock to the tip of the permanently attached Krebs Custom four prong flash hider affixed to the chrome lined 14 inch barrel. An ACE hinge connects the Magpul CTR to the rear trunnion and offers a user the option of folding it for compact transport. The KV 13 measures 26 inches with stock folded. Weight of the Krebs Custom KV 13 is slightly over 8 pounds.

Tapco SAW style pistol grip and Krebs Custom Mk IV safety lever round out the Krebs’ KV 13. The Krebs Mk IV safety lever allows for the safety selector to be manipulated by the trigger finger without changing the firing grip on the weapon. This nuance has an immediate real world improvement on handling the VEPR. The ability to keep your hand in a firing position while working the safety allows for faster first shot reaction times. The SAW style grip better aligns the shooter’s hand and fingers when making a precise shot. All of these modifications are not merely “smoke and mirrors,” but rather concerted effort to improve upon VEPR performance and accuracy; while maintaining AK qualities of ultra reliability, ruggedness, and simplicity. Marc Krebs is an ideal candidate to lend his experience to improving the VEPR AK without altering it beyond what is feasible or practical.

In combination with the Krebs KV 13, one concept that has piqued interest is setting up Kalashnikov AK with extended eye relief magnified optic mounted on a railed forend; for lack of a better term a “scout scope” configuration. Credit must be given that this configuration was initially noticed at various sources including Tactical Response and Suarez International. The AK with forward mounted scope is simple and builds on previous ideas advocated with other firearm types such as bolt-action and lever-action rifles. With the ever increasing popularity of AK rail systems, red dot optics are becoming the norm. AK shooters have discovered the advantages offered via red dots in terms of accuracy and speed when engaging targets; why not take this a step further and use a scout scope with minimal magnification and a cross hair that does not rely on batteries?

A Leupold FX II 2.5x28mm IER scope was mounted on the Krebs KV 13. The Leupold optic added only a little over 8.5 ounces to the total rifle package. The Leupold 2.5x IER scope offers the capability to engage multiple targets in rapid sequence more accurately compared to open sights and at greater distances. As many “maturing” shooters can attest to the single focus plane with the reticle is easier to shoot accurately than coordinating front and rear sights. Shooters familiar to red dots will be pleasantly surprised by the utility of the Leupold 2.5x Scout scope. The Leupold scope gathers light in dim light, the crosshair is hard to beat for aiming point, and the magnification aids in accuracy and finding lanes of fire when firing in dense crowded areas. The Leupold is far superior to any open sight and allows for reliable target recognition in low light compared to open or red dot sights. The Leupold 2.5x Scout Scope was mounted via Weaver See-thru rings.

The Bindon Concept of keeping both eyes open and having a reticle appear to float in front of the rifle works with the forward mounted scout scope. By keeping both eyes open the Leupold reticle was quick to locate at ranges out to 100 yards and closing one eye provided fine tuning at distance. An illuminated center dot reticle would have been even better for CQB distances. A back-up to using the scope at close range was still sought. Range time indicated that steel man poppers were reliably hit when taking advantage of the “see-thru” rings and indexing off of the KV 13’s rifle’s front sight post – sort of a “caveman EOTech” concept. The goal was not to inhibit the ability to engage extreme CQB targets if the need arose.

Multiple 5.45×39 loads were tested with the Krebs Custom KV 13 such as Wolf, Tula, Silver Bear in 60 grain and 70 grain varieties. A new addition to the 5.45×39 ammunition realm was also accessed – Century International Arms’ Red Arms Standard brand. Red Army Standard 5.45×39 69 grain ammunition is offered in handy Range Packs (180 rounds) as well as 30-round boxes. Red Army Standard is manufactured by the same factories that produced billions of rounds of ammunition for the Soviet Red Army and Warsaw Pact nations. The Range Pack boxes indicated Ukrainian manufacturing. (Century International Arms Red Army Standard will be available in other popular Warsaw Pact rifle calibers such as 7.62x39mm (123 grain FMJ) and 7.62x54R (148 grain FMJ). Of special note with the 5.45×39 is the still available surplus 53 grain 5.45×39 ammunition. This is loaded with the 7N6 “poison pill” bullet that first gained notoriety in the Soviet-Afghan War. A unique design feature of the 5.45×39 cartridge is an air space inside the jacket at the bullet’s tip. The air space serves to shift the bullet’s centre of mass toward the rear, possibly contributing to its very early yaw when impacting a soft target. In addition, on bullet impact with tissue, the lead core just behind the air space shifts forward into this space. This is particularly devastating when striking soft tissue. This shift of lead occurs asymmetrically and may be one reason for the peculiar curvature of the bullet’s path in the last half of its travel through tissue. One downside typical to most surplus ammunition is that it utilizes corrosive primers.

Two 5.45 ammunition loadings were of interest when combined with the magnified forward optic; Hornady 60 grain VMax and Dynamit Nobel 59 grain HP loading. The Hornady 5.45×39 load is a godsend for AK owners looking for a quality U.S. made ammunition choice for their rifles. By good fortune the Dynamit Nobel 59 grain 5.45×39 was discovered at Century International for sale several years ago with a couple cases acquired. The Hornady 60 grain VMax bullet mated to steel cases is starting to arrive on dealers’ shelves in quantity. The Hornady VMax loads delivered accuracy in the 1.5 inch range at 100 yards with the Dynamit Nobel producing similar results. The other ammunition brands produced 2-3 inch groups at 100 yards. The Leupold FX II 2.5x28mm IER scope proved advantageous in ascertaining KV 13 accuracy compared to open sights or red dot. The 70 grain 5.45×39 loads produced 2,770 fps and the 60 grain nudged high 2,800 fps when fired thru the Krebs KV 13 5.45 with the 53gr surplus ammunition clocking in at 2,950 fps.

The Krebs KV 13 5.45mm combined with magnified optics mated to quality ammunition in the form of the Hornady VMax is what many AK connoisseurs have been waiting on. There are many pages written in magazines and on various internet forums about what it would take to turn the AK into more of a general purpose rifle. The hold-up to more effective use of the AK at ranges past 200 yards usually revolves around solid scope mounting and ammunition of greater quality than what is offered in the surplus realm. The Krebs KV 13 solves this conundrum.

Team Tactic drills are a favorite method to evaluate a fighting rifle. One gets a good sense of the way a weapon handles along with reliability due to the sum of ammunition expended in short time frames characteristic of these Team Tactic drills. The full gamut of rifle manipulation is encompassed in Team Tactics training evolutions – handling around cover while engaging designated targets, accuracy to effectively strike at both distance and CQB ranges, magazine changes, and reliability once a weapon gets heated up. During the evaluation over 500 rounds were fired with no issue. Anecdotally, the recoil impulse with the Krebs Custom KV 13 seemed smoother than other AKs tested to date. While the 5.45×39 is not considered a heavy recoiling round by any stretch, the KV 13’s recoil and muzzle rise was negligible even when firing multiple rounds in quick secession. The 8 pound KV 13 balanced well with kudos given to the Krebs’ KeyMod set up keeping weight centered or even slightly rearward of action versus front heavy as most quad rail forends are.

Is the Krebs KV 13 5.45×39 AK with forward mounted scope the answer for everyone or going to displace red dot optics in the tactical realm? No, but it is a valid concept that should not be scoffed at by individuals until fully assessed for what it offers and brings to the table in terms of capabilities offered. The AK with forward mounted scope probably has more appeal to the civilian having to satisfy multi-purpose roles based on budgets or what can be realistically supported logistically. A civilian does not have the luxury of checking out mission specific firearms based on mission brief. The Krebs KV 13 is a definite improvement over the standard AK platform. However, individual preferences dictate comfort level when contemplating choosing a non-typical profile rifle such as the KV 13 with some appreciating and other discounting what it offers.

It is a safe bet that everyone reading this magazine has been drawn by some inexorable force into considering a weapon that made no sense when one’s “needs” are analyzed empirically. Often times these firearms are sentimental favorites based on an affiliation with an original model not readily accessed. A recent phenomenon along these lines is represented by the Century International Arms semiautomatic AES-10B patterned after a Romanian version of the RPK light machine gun. The AK series of weapons are experiencing a renaissance/resurgence in popularity in the U.S. The AK’s association as the “enemy’s” weapon seems not to deter its growing popularity in the U.S. This stems from many factors: rugged reliability, price point, reasonably priced ammunition, an appreciation of 7.62×39 terminal ballistics, and the ever increasing quality and quantity of after-market parts.

The affinity toward AK platforms for many started with the affordable Romanian manufactured AKs arriving in the early 1990s, before the 1994 Assault Weapon Ban went into effect. While not aesthetically pleasing, ergonomic, or as inherently accurate as an AR, for many the AK was quickly turned into a “go to hell” rifle. A “go to hell” label translates into what rifle you would reach for when the world goes in the pot and you rush into your safe room looking for a rifle and pre-loaded magazines. The AK serves this role for many based on reliability no matter what field conditions it finds itself in. Smoking hand guards on an AK means it is only getting warmed up. Of course, this is an over simplification in the same vein that ARs are indeed more reliable than most give them credit for and AKs are more accurate.

The Century AES-10B RPK weighs approximately 12 pounds empty and the 23-inch 1:10 twist barrel lends to an overall length of 42 inches with wire stock unfolded and 34.25 inches folded. The wire folding stock is a unique AES-10B feature compared to most RPKs affixed with wooden stocks. The AES-10B’s wire stock comes with the added benefit that the rear trunnion is already configured to accommodate standard AK rear stocks. This is useful if an owner wants to switch out the rear stock to better suit their individual preferences unlike other semiautomatic RPK clones on the market. Most RPK clones are limited in this area fitted with either a “clubfoot” RPD-style stock or oversized AK wood stocks associated with Yugoslavian M72 versions of the RPK with no easy means available to switch out stocks unless the rear trunnion is modified. The AES-10B’s heavy barrel measures approximately 3/4 inches in diameter and is U.S. made sans chrome-lining. The U.S. made barrel contributes to the magical number of needed U.S. parts to pass BATF muster. The M14:1 LH threaded muzzle comes equipped with a slanted muzzle brake. The AES-10B RPK features an integral bipod that folds underneath the barrel until deployed. Research and observation indicates that the stamped receiver is reinforced and enlarged around the front trunnion connection to the barrel.

The RPK configured AES-10B differs from the typical AK/AKM in a number of design improvements intended to facilitate its role as a light machine gun. The barrel is lengthened and thickened to not only increase muzzle velocity, but also allow for increased heat capacity during extended fire sessions. Along these same lines the barrel is mated to a reinforced receiver housing reflective of its sustained fire role. 40-round stick and 75-round drum magazines were developed with the RPK to improve its combat rate of fire. The RPK was outfitted with folding bipod to stabilize it during deployment assisting a squad or platoon in advancing towards its objective or defending from an attack. The RPK rear sight is outfitted with sliding windage mechanism to improve fire accuracy and ease of adjustability. The original RPKs featured a rear stock identical to the Degtyarev RPD 44 machine gun. The interchangeability of parts between the RPK and AK/AKM is high including magazines.

As with most weapons adapted to suit a role beyond its original design intent the RPK has some drawbacks. The combination of firing from a closed bolt and fixed barrel translates into an operator having to use good fire discipline or the RPK will overheat and fail. Optimal sustained fire is around 80 rounds per minute. If overused, chambered rounds could “cook off;” not to mention barrel damage. The fixed barrel combined with inability to fire via belt fed ammunition cause many to question its utility as light machine gun. Comparisons to the U.S. BAR are common, though not necessarily accurate considering cartridges fired and different operating design ala closed bolt for RPK compared to open bolt for BAR. The RPK design commenced in the late 1950s and finalized by the Red Army in 1961, but did not enter wide-spread service until 1964. Each infantry squad was issued one RPK along with a 75-round drum magazine. The RPK continues in service in numerous post-Soviet countries and allies to this day with hundreds of thousands produced. The Kalashnikov’s gas piston operating system’s greatest benefit is reliability in more diverse environments due to reduced sensitivity to dirt and grime, not to mention the more powerful leverage it applies to the bolt compared to direct gas. Another key component is looser tolerances in the moving parts, giving it more latitude to function when dirty from field conditions or not cleaning after firing numerous rounds.

Century literature details an interesting story behind the AES-10B RPKs – though perhaps apocryphal. These rifles are the semiautomatic only version of the Romanian RPKs issued to elite paratrooper forces during the Communist Ceausescu Regime. The extremely rare AES-10B variant currently being offered is built using a small cache of rifles found in a sealed building in the Transylvanian factory town of Cugir. These were apparently to be issued for a planned massive troop build-up on the Romanian/Hungarian border when tensions flared between the two Warsaw Pact member states. Luckily, cooler heads prevailed and a crisis was averted. The rifles are identified by featuring a side folding stock, integral carry handle and bipod.

The Century AES-10B RPK was enjoyable to shoot at the range and amazingly effective in supplying firepower downrange. While not surprised at the lack of sub-MOA accuracy, it was very possible to hit man sized Mike Gibson Manufacturing (MGM) precision rifle targets placed at 200 and 300 yards. The prone position utilizing the integral bipod was predominately used for the evaluation; though standing and kneeling off hand positions were experimented with no problem even with 75-round drum magazines inserted. Fortunately, Echo Valley Training Center has installed two permanent “foxholes” created by turning large diameter concrete culvert pipes end wise into the ground complete with firing step in the bottom. Echo Valley Training Center features multi-stepped target berms that are strewn with reactive steel targets, fluid drained automobiles, and moving targets at ranges varying from 150 yards out to 350 yards. The protected firing positions were perfect for evaluating the AES-10B RPK in its intended fire support role. While certainly not comparable to a belt-fed switch barrel machine gun, a relatively large volume of fire was possible, especially when used with a high capacity 75-round drum with attention paid not to exceed 60 rounds per minute for any extended fire sessions. Two 40-round magazines come with AES-10B and standard 30-round AK magazines work fine as well.

The semiautomatic AES-10B firing the 7.62×39 cartridge is very controllable with its extra weight over the standard AK. In comparison to the RPK’s big brother, the PKM chambered in 7.62x54R, the RPK is a pleasure to shoot. The PKM medium machine gun is a handful compared to the semiautomatic RPK firing the intermediate 7.62×39. The wire folding stock did not prove problematic in terms of comfort or proper aiming with the AES-10B. Original thoughts of replacing the folding wire stock were shelved. At ranges under 400 yards one would not be considered terribly under-gunned with the AES-10B RPK semiautomatic. The car placed 200 yards away could not withstand the AES-10B fire. Rounds penetrated sheet metal, seats, or anything else in its path as the 7.62×39 easily passed through the car; only the wheel rims and engine block provided a modicum amount of resistance.

Multiple 7.62×39 loads were tested with the Century AES-10B such as Hornady, Wolf, Barnaul, Egyptian and Yugoslavian surplus. Barnaul Silver Bear zinc-plated and Wolf Ammunition steel cased 122gr and 124gr loads hovered in the 3 inch range at 100 yards with surplus Egyptian and Yugoslavian 7.62×39 producing similar groups. I found this acceptable considering my eyes and the non-target style battle sights that are found on the AES-10B. Unlike typical AK sights, the AES-10B’s rear sight was windage adjustable. The sights were right on out of the box. The G2 trigger was typically smooth and with reasonable pull weight measuring slightly over 5 lbs. The notorious AK trigger “slap” was present, but not all that distracting or painful if shooting gloves were used. No malfunctions were encountered in over 900 rounds fired during three range sessions while compiling this article. Interestingly, both the Egyptian and Yugoslavian surplus ammunition feature brass cases. One downside to the surplus ammunition is that it does utilize corrosive primers. Something the Russians and other ex-Soviet bloc states insisted on using due to concerns with cold weather ignition and long-term storage capabilities offered by corrosive primers. However, stocking up on it cannot be resisted considering that it can be still found at .25 cents a round or lower. Corrosive ammunition is not the destroyer of rifles many will lead you to believe as long as proper cleaning methods are followed to remove elements left over from the primer residue.

The long anticipated Hornady 123gr SST bullets mated to steel cases are starting to arrive on dealers’ shelves and were tested with the AES-10B. Seems that the original Hornady 7.62×39 loads that featured the V-Max bullet is being replaced with the SST bullet which represents a more controlled expansion with its bullet construction in lieu of the more varmint style V-Max construction. The SST loads delivered with accuracy in the 2 inch range at 100 yards. In all fairness, a magnified optic would have probably produced better accuracy results in lieu of the open sights, especially with the Hornady loads. The Century AES-10B comes equipped with a side rail scope base permitting the install of optics if desired and just not Com-bloc varieties with the advent of Picatinny-style side mounts. The thought of mounting a red dot or low magnification scope was toyed with ala what is being seen overseas on our troops M240/M249 weapons. The accuracy levels exhibited by the Hornady 123gr load added emphasis to this thought process, but was ultimately not employed. Gilt edge accuracy is not the goal with the AES-10B; it is a fighting rifle measured by a different set of parameters. Individuals will have to decide for themselves if the AES10B is worthy of a red dot or magnified optic.

Some will be attracted to the Century International Arms AES-1OB for its proven potential as a weapon, while others will find it the closest opportunity they will have to own a working replica of a historical firearm. It is very possible to state that the Century AES-10B was an enjoyable rifle to shoot and handle at the range. The AES-10B is an interesting piece of firearm development history that can still perform on the range.

Sometimes a firearm gem is found by accident. Such is the case with the Century International Arms Polish TTC semiautomatic pistol chambered in 7.62×25. It is a “Made in Poland” Tokarev TT-33. The Poles used wz48 nomenclature for their Tokarev version. Many of the Russian/Soviet designs are coming to be better appreciated since the Cold War and may be a result of the easing of import restrictions allowing for easier access; thus more familiarity as the decades have passed since the late early 1990s.

The Tokarev TT-33 was adopted in 1933 to replace the aging Nagant 1895 revolvers in Soviet service. An earlier variant, the TT-30, was originally adopted in 1930, but design changes were incorporated involving the trigger, barrel, omission of the removable backstrap, and frame to simplify production that led to the change of nomenclature to TT-33. For reference sake, the Tokarev blends exterior aesthetics of the 1903 Browning with internal workings of the Browning 1911. The pistol is a single-action, semiautomatic, recoil operated weapon patterned after Browning’s swinging link design, but modified in the Tokarev to simplify production. Essentially, the barrel and slide are locked together for a fraction of an inch during recoil allowing for the bullet to exit and pressures to drop before the empty case is extracted and ejected. The Tokarev is not a direct copy of Browning’s design and exhibits unique features of its own. The Tokarev’s trigger assembly is a modular unit and has locking lugs the full circumference of the barrel compared to only the top of the barrel in the 1911. Most semiautomatic reliability issues stem from defects in the magazine. This is addressed in the Tokarev design with cartridge feed lips machined into the receiver versus the magazine to enhance reliability and prevent damage that occurs when magazines are slammed home. The Polish TTC is fed from an eight-round single stack magazine and weighs 30 ounces with an overall length of 7.6 inches and a 4.6 inch barrel. The TTC’s width is less than that of the iconic 1911. Grip width is often commented on as being important for carryability and allowing for people with smaller hands to hold comfortably.

The Tokarev was the issue handgun for Soviet officers during World War II though many Nagant revolvers were still in use. The Tokarev fires the bottlenecked 7.62×25 cartridge, which is very similar to the German .30 cal. Mauser Automatic 7.63×25 design. The 7.62×25 was also used with the PPSh-41 submachine gun and other weapons in the Soviet armed forces. Sources report that German troops frequently used Tokarevs picked up on the battlefield. The purported interchangeability between the Soviet and German rounds further encouraged this practice. This is cautioned against since the Soviet 7.62×25 cartridge is loaded to higher pressures compared to the German round. The Tokarev’s proven ability to function under the harsh conditions of the Eastern Front was appreciated then by soldiers on both sides and now by collectors.

Ballistics are eye opening with 85-90gr bullets accelerated to 1,300+fps. The round had a reputation for potency compared to other contemporary pistol cartridges of its era and even now is capable of penetrating modern soft body armor due to its high velocity. The Tokarev’s reputation for reliability, accuracy, and lethality was proven in the greatest land conflict of the 20th Century. The Tokarev stayed in service with the Soviets until 1952 when it was officially replaced by the Makorav. The Tokarev could still be found in use with Soviet armed forces in the 1960s and Soviet Police into the 1970s. It is still in service with North Korea and China. Versions of the Tokarev were manufactured in Poland, China, Yugoslavia, Hungary, Romania, North Korea, and Egypt.

Two of the most common complaints of the original design were the lack of manual safety and grip angle. The Polish Tokarev version imported by Century has a manual thumb safety retrofitted on the frame behind the trigger to satisfy import regulations. The installed safety is a simple trigger block and is done in a fashion better than most safety add-on modifications that can be found on various other versions of Tokarev imports. Grip angle, while different than a 1911 or Glock, was not problematic during testing and evaluation. The only grip issue detected was the tendency for the hammer/slide to come into light contact with webbing around the thumb of the firing hand. This was only noticed after shooting several magazines and was remedied with a shooting glove. Importantly, the Polish Tokarev’s functionality was not compromised. The TTC was put thru the same regimen of testing as any other handguns evaluated. Century includes two magazines with the TTC and a leather holster with chest strap that also allows for spare magazine to be carried. Recoil/muzzle blast was as expected with any handgun sending rounds downrange at 1,350+fps.

. Multiple range visits over several months taking advantage of inexpensive surplus ammunition and affordable Wolf Ammunition 85gr 7.62×25 in both FMJ and JHP configurations produced no malfunctions with over 900 rounds fired. The Tokarev seemed to always find its way to the range no matter what was being tested with a few magazines fired with it. The inexpensive surplus ammunition supply is a major factor in the upsurge of popularity with the Polish TTC handguns. Solid reliability and surprising accuracy only reinforces this trend as word is spread about what is being received for well under $300.

The Polish TTC handled numerous runs through handgun courses designed for competitors using more modern pistols without an issue. Holsters designed to handle a 1911 served to carry the TTC during range visits. This worked as long as holsters were not custom or form fitted for the 1911 profile. The TTC’s magazines were not drop free, but once this was determined reloads went smoothly. The basic U-notch rear and small, narrow bladed front sight gave a decent sight picture as plate racks, steel poppers, and paper silhouette targets were engaged. The narrow front blade proved an asset in longer range shooting as daylight was still present on either side of the front sight in the rear notch allowing for a way to gauge hold better than the three-dot configurations commonly found on more modern handguns. Accuracy was impressive both in terms of group size and effective engagement distances. A steady two-handed hold combined with slow fire produced constant hits on steel popper targets at 50 yards. This is a combination of flat shooting ballistics and solid design and construction.

Take-down of the wz48/TTC is very similar to anyone familiar with a bushing barreled 1911 barrel design. Cleaning was a simple matter with no idiosyncrasies. The Century Arms TTC proved a pleasant surprise along with the potency of the 7.62×25 cartridge. Everyone with an interest in owning an operating piece of history is encouraged to try a Century Arms TTC offering for themselves.

The AK SBR reviewed herein started as a Romanian 7.62×39 AK Draco pistol imported by Century International Arms. Certain weapons evolve over time as a user searches for best utility. Experience with a 5.45×39 Krinkov led to an appreciation of what a SBR offers in terms of portability and handling. Almost immediately after the economical Draco AK pistol was uncovered the quest to maximize it began.

The Draco SBR quest began in earnest upon reviewing a Suarez International Warrior Talk forum discussion about adding a rear sling point on a Draco AK pistol. The work involved with the rear sling attachment was not significantly less than what would be involved to just alter the existing rear trunnion of the Draco to accept a stock. Red Jacket Firearms was turned to in assisting with the Draco SBR project. 7.62×39 Krinkov style rifles or kits are currently scarce and the Draco SBR seemed a good alternative.

The Draco was fired in its original pistol configuration before converting it into a SBR. The Draco AK pistol, while interesting, lacked much in terms of accuracy past normal handgun ranges with added negatives of weighing 5.5 pounds and muzzle blast of a rifle round. Draco is the Latin word for dragon. The Draco AK certainly lived up to this vision of a fire breathing apparition with substantial amounts of muzzle blast and flash. While definitely categorized as a fun firearm, the Draco in its pistol form is limited in its effectiveness. A Krebs Custom Quad Rail was added to the Draco while still in its pistol form in an effort to increase its accuracy and effective range potential. An Insight Technology M6x laser/light and various red dot sights were utilized to no avail with the AK pistol. The results still were not satisfactory.

Century International Arms imports the Draco AK pistol. The Draco AK pistol utilizes the same forend length as a standard AK. This simplifies finding accessories for it compared to the more specialized Krinkov versions with reduced length forends. The piston length is not the same. Yes, the 11inch barrel length is longer compared to an 8.5inch barreled Krinkov, but this is a viable compromise considering alternatives are slim when searching for a 7.62×39 Krinkov kit. The Draco has a unique front gas block and sight compared to other full size AKs and the rear sight is modified for shorter ranges expected from a pistol.

Turning the Draco AK pistol into a SBR transforms it into a more serious firearm. Yes, the 11 inch barrel sacrifices some performance versus 16 inch barrels, but this is the price for any SBR. Increased handling and portability more than compensates for any velocity lost. The 7.62×39 is less affected in this regard than 5.56 or 7.62×51 chamberings. Lessons rediscovered in Iraq and Afghanistan about terminal ballistics further enhances 7.62×39 AK credentials. However, the lack of a rear stock nestled in your shoulder impacts effectiveness. This is based on multiple points of contact represented by a shoulder stock as compared to a handgun. This consists of shoulder, cheek, and hands spread further apart for more stability compared to a handgun.

Three performance upgrades were sought in converting the Draco AK pistol into the Draco SBR. The first, and most important, involved modifying the rear trunnion to add a stock. Second, based on previous experiences with a 5.45×39 AK SBR, was foregoing the standard wood forend by replacing it with a Krebs Custom Quad rail. Lastly, wanting to take advantage of the first two improvements, an Aimpoint T1 optic was added to the Krebs Quad rail, which is a vast improvement over the standard open sights. This only reinforced correctness of decision to add a stock to the Draco to better take advantage of 7.62×39 potential and AK handling characteristics.

This SBR project would not have been possible without the involvement of Red Jacket Firearms. Red Jacket has established itself as a major resource for U.S. AK devotees. A quick phone call to Red Jacket owner Will Hayden discussed expectations for the Draco. Red Jacket modified the rear trunnion and added a DPH folding stock with ACE folding hinge. The Draco was given the once over by the experienced Red Jacket gunsmiths while it was in Louisiana. It would have been foolish not to take advantage of Red Jacket’s experience with AKs while the Draco was there for the rear trunnion modification. Red Jacket tuning included checking magwell dimensions, function of action, polished and smoothed rails along with removing any machine marks from the bolt head and carrier. The front sight and gas block were checked for alignment, which is a common AK issue. During assembly after paint, Red Jacket noticed a discrepancy with the standard Romanian fire control group hammer and sear engagement. Red Jacket installed a G-2 unit which is a proven trigger group with Red Jacket projects. Further inspection revealed the safety lever barely caught the hammer and had the possibility of an accidental discharge. This was repaired by extending the contact point of the selector with a weld, shape to fit handwork and refinishing to match. The metal surfaces of the Draco received a Gunkote application. Upon the Draco’s return it measured 32.5 inches with the DPH stock deployed; 24 inches folded, and weighed slightly over 8 pounds. These measurements included Krebs Custom Quad rail, Aimpoint T1, offset Troy vertical grip, and YHM Phantom flash hider.

Red Jacket Firearms has been a Class 7 manufacturer for over a decade. What started out as private projects involving AK type of weapons quickly evolved into a main product line for the company. The ZK model and Saiga shotguns, including integral suppressed versions of the Saiga shotgun, being the most sought after firearms from Red Jacket along with a relatively new offering involving accuracy enhancements to Saiga rifles. Not wanting to oversimplify, Red Jacket is a true custom gunsmith with many types of weapons available. Will prides himself on producing weapons that are capable of hard use with a reputation for ruggedness, reliability, and accuracy.

The Krebs Quad Rail was simple to install securely to the Draco, thus multiplying potential options for adding accessories to the rifle. As expected from Krebs, the Quad Rail was well made and did not move once installed on the Draco SBR. Another benefit of the Krebs Quad Rail is that it allows for better ventilation around the barrel, thus cooling it down faster after long strings of fire. The Krebs Quad Rail could be considered just as essential to getting the most out of the Draco SBR as adding the rear stock; without the Krebs Quad Rail it would have been impossible to forward mount the Aimpoint T1 sight or any other optic for that matter.

Many will find the Krebs Custom Quad Rail as an invitation to accessorize the Draco with lights, lasers, vertical grips, etc. Individuals will have to judge for themselves what is necessary kit without compromising handling. A vertical forward grip was added to the Draco SBR via Kreb’s offset rail adaptor. The AK47 magazine’s curvature can interfere with a vertical forward grip during magazine changes impacting reloading efficiency. The Kreb’s offset rail adaptor eliminates this likelihood and allows for a vertical grip to be positioned per individual shooter preference. The vertical foregrip has fast become a standard accessory on any rifle or carbine equipped with a forward accessory rail. The increased leverage and control offered by the vertical foregrip aids in weapon manipulation and stability when firing. The vertical foregrip’s advantages are further magnified with the ever increasing amount of accessories being placed on weapons equipped with Picatinny 1913 or similar rail systems. Loading up a weapon’s forend will effect handling. An Insight Technology M6x tactical light/laser illuminator was chosen due to it combining both a high intensity light and laser aiming module in one compact housing. The Insight M6x was configured with the long arm remote pressure pad switch for activating the laser and/or light with the support hand without having to alter firing grip. Another vertical forward grip used with the Draco SBR was the Police Ordnance Company MTL 225 distributed by Century International Arms. The MTL-225 combines a vertical grip with a high intensity 225 lumen LED tactical light all in T6 aluminum housing weighing in at slightly less than 16 ounces. The MTL-225 requires mounting fully forward on the Draco SBR so as not to interfere with magazine changes. A review of weapons appearing in the hands of our troops fighting overseas or domestic LE tactical teams will confirm popularity, utility, and appeal related to vertical foregrips and tactical lights and lasers.

Range T&E followed established protocol for combat rifles. After a quick verification of 25 yard sight zero, evaluation commenced with a function test involving firing several magazines in rapid succession at various steel man targets and vehicles that dot the range. While not unique, this is a good way to establish a baseline for reliability. Let’s face it; if an AK-type weapon does not have pristine reliability, its major attribute is nullified. A vertical forward grip is perfect for keeping your hand away from a hot barrel. A more comprehensive 100 yard sight zero confirmation took place after functionality was established. The Krebs Quad rail allows for the open sights to be viewed down the recess between rails system if one chooses not to mount an optic. The Aimpoint T1red dot sight offered the capability to engage multiple targets in rapid sequence compared to open sights. As many “maturing” shooters can attest to the single focus plane with the red dot is easier to shoot accurately than coordinating front and rear sights.

Brass cased Egyptian and Yugoslavian 7.62×39 surplus ammunition was used for the bulk of the testing with Wolf Ammunition Polyformance 122 and Military Classic 124gr loads also used in conjunction with Barnaul and Golden Tiger 7.62×39 loadings. Accuracy was acceptable for an AK, or any other combat rifle using iron sights or non-magnified optics, at 3-4 inches at 100 yards. One downside to most surplus ammunition is that it does utilize corrosive primers. Something the Russians and other ex-Soviet bloc states or clients insisted on using due to concerns with cold weather ignition and long-term storage capabilities offered by corrosive primers. The Egyptian ammunition is labeled as non-corrosive, but was handled as if it was corrosive to take no chances. Corrosive ammunition is not the destroyer of rifles many will lead you to believe as long as proper cleaning methods are followed to remove elements left over from the primer residue. During several range visits in both its pistol and SBR form, the Draco fired several hundred rounds downrange. The weapon was cleaned between range visits due to the use of corrosive ammunition.

Further range testing of the Draco consisted of repeating numerous drills and exercises experienced via training with Suarez International, Storm Mountain, and Tactical Response. Firing while moving as well as behind cover, reloading drills, transitions between shoulders depending on cover orientation, and engaging multiple targets arranged around “no-shoot” targets all helped put the Draco SBR through its paces. While not as subtle or tame as an AR-15 or AK74, the Draco’s muzzle blast and recoil was not prohibitive allowing for fast double and triple taps on selected targets, especially at CQB distances. The welded muzzle nut that comes on the Draco pistol was removed allowing for access to the weapon’s M14x1LH muzzle threads. Initially, a typical AK slant style muzzle device was added. A Yankee Hill Machine (YHM) Phantom flash hider quickly replaced this. The Phantom flash hider is not only effective at reducing muzzle signature, but allows for the quick mounting of a YHM suppressor if desired. This was done occasionally with no detriment to the Draco’s accuracy or reliability. The Aimpoint T1assisted in engaging targets at close distances with the red dot easy to pick up rapidly, while at the same time allowing for more than enough accuracy out to a couple hundred yards due to the red dot’s superimposing an aim point on the target while not totally obscuring the target due to the dot’s not being oversized.

The Draco SBR handled as expected from a SBR AK benefitting from a shortened barrel combined with AK reliability. Red Jacket’s tuning could be detected in smoothness of manually operating action and slickness of magazine changes. Targets of opportunity located around the range such as car hulks, manhole covers, and steel MGM Precision Steel targets were engaged repeatedly outside of designated courses of fire.

Some will question why go through the hassle for an SBR. The answer, as with most things related to firearms, is personal preference. This review should encourage readers to look outside the box when making decisions concerning weapon choices. Did the Draco, with added enhancements, turn out to be a good investment of time and money? Yes, in all aspects, including shootability, reliability, functionality, and lethality. Not much more can be asked from a rifle.
