A manufacturer that is developing into a noteworthy force in the US for all firearm categories, albeit sporting, competition, tactical or personal defense, is Sturm, Ruger & Co. This epiphany was caused by the recent introductions of AR style rifles, a .300 Blackout Mini 14 and most recently the bolt action Precision Rifle. This bolt action is unlike any other offered by Ruger. The Precision Rifle is Ruger’s take on creating a highly accurate long range bolt action detachable magazine rifle; all the while keeping it affordable.

The Ruger Precision Rifle will surely be considered by any department or individual pondering a precision bolt action tactical rifle; its reasonable price will only reinforce this. It is available from the factory in various calibers, .308Win (tested herein), 6.5 Creedmore, and .243Win. The Precision Rifle arrives with many notable features including fully adjustable folding rear stock, threaded muzzle, Picatinny rail running along the upper receiver out to the end of the forend, and Ruger’s adjustable Marksman trigger. One thing that distinguishes the Precision Rifle, functionally and aesthetically is the ability to accept multiple types of detachable magazines. Ruger has devised a patented Multi-Magazine Interface (MMI), allowing them to greatly increase magazine compatibility beyond only one type. The Ruger Precision Rifle can use DPMS, M110, SR25, PMAG, AICS and some types of M14 magazines. Two 10-round Magpul PMags arrive with the Ruger Precision Rifle.

The Precision Rifle evaluated herein is chambered .308Win with 6.5 Creedmore and .243Win available. Many are already salivating at the thought of a long action version chambered in .300WinMag or even .338Lapua appearing in the future. The Precision Rifle is centered on a modified Ruger All American bolt action. Overall length is 38.25 to 41.75 inches with the 20 inch hammer forged 4140 chrome-moly steel free-floated medium profile barrel (.75 inches at muzzle) featuring 5R 1:10RH rifling. According to research for this article 5R rifling places a land opposite each of the barrel’s grooves, resulting in less aggressive upset and distortion of the bullet as it engages the rifling, thereby aiding in accuracy. The 5R rifling also features less sharp edged lands than those present in conventional-style rifling, reducing powder fouling and jacket failures. The company further optimized the Precision Rifle’s accuracy by utilizing the tightest possible chamber while also taking extra care to ensure a centralized chamber and minimal headspace. The muzzle is 5/8×24 threaded. A Ruger provided thread protector can be removed to make room for installing other muzzle devices. The Precision Rifle weighs in at 9.7 pounds when empty.

The Precision Rifle’s lower magazine well is machined from aerospace-grade 7075-T6 aluminum Type III hard coat anodized for maximum durability. The upper receiver and bolt are CNC-machined from pre-hardened 4140 chrome-moly steel. The upper receiver has an integral 20 MOA Picatinny rail secured with four, #8-40 screws for increased long range elevation capabilities. The three lug full diameter All American bolt has a 70 degree throw along with dual cocking cams. A bolt disassembly tool is stored in the bolt shroud. The bottom bolt lug is ideal for stripping rounds from the detachable magazines. Ruger decided to go with an oversized threaded on bolt handle for easier rapid working of the action; after all you have a high capacity magazine worth of ammunition available. If a user so chooses, a different bolt handle can be installed.

Ruger has chosen a different path from typical bedded stocks or even the chassis systems that seem to be gaining in popularity. The Precision Rifle utilizes a linear in-line recoil path to maximize accuracy potential by directing unwanted movement and vibration straight back into the buttstock. This minimizes impact on barrel harmonics when the rifle is fired; the key here is consistency during the firing impulse. The stock is threaded into the rear of the receiver in effect becoming a part of it.

The AR influence is hard to escape for any rifle nowadays-even bolt actions. Any AR style stock can be used over the buffer tube like projection if a user feels the MSR stock is not to their liking for some reason. The Precision Rifle’s barrel can be easily changed using techniques and tools common with AR15 rifles. Ruger is using a 15 inch free floated Samson Evolution KeyMod AR handguard. As with the buttstock most AR style forends can be used if a user wants to retrofit with one. The same can be said of the AR style pistol grip and fire selector switch.

The 1:10 twist hammer forged barrel gets the most out of the various wide ranging .308Win loads on the market i.e. 147 grain to 175 grain. The Precision Rifle’s relatively light weight, compared to other precision rifles on the market, gives improved portability and above average handling characteristics for a precision tactical bolt action rifle. Many tactical rifles, while accurate, resemble boat anchors when it comes to handling due to weight and stock configuration; not the Ruger Precision Rifle.

One has to be impressed with Ruger’s design work in getting the Precision Rifle to accept and feed via popular detachable magazines. Reliability is something that can not be compromised. The oversize bolt and smooth passage of the bolt in the raceway allows for minimal disturbance of the rifle when the bolt is worked. The Precision Rifle’s oversized bolt handle and detachable magazine are features that lend themselves to performing in a tactical environment and serve to maximize the Ruger’s potential.

Many will wonder what is the purpose or niche for the Ruger Precision Rifle. Why not just use a tuned semi-automatic AR in lieu of the bolt action Precision Rifle? The answer lies with individual or department preference for a bolt action. This could be based on cost, public perceptions, or myriad of other reasons. Ruger has designed a rifle that is rock solid with characteristics making it conducive to accurate shooting from a variety of positions. The forend handles bipods or sandbags with equal aplomb. The Ruger Precision Rifle is not exclusively designed for shooting from the supported prone or bench position. The stock allows for offhand and other types of supported fire if needed. Think hood/trunk of a squad car or other field expedient positions. The ergonomics of the adjustable length of pull Ruger MSR buttstock allows for a comfortable, repeatable cheekweld. This is combined with a Magpul AR pistol grip making hand placement conducive to pulling the Ruger Marksman trigger smoothly to the rear.

The first requirement of a tactical rifle is precise accuracy. A Leupold Mark IV 3.5-10x50MM scope with mil dot reticle was mounted on the one piece Picatinny rail above the Precision Rifle’s receiver via Leupold Mk IV rings. It has the typical great Leupold reliability, clarity, and image quality with a near perfect variable power range for a precision .308Win rifle. Importantly, Ruger provides the Precision Rifle with an integral Picatinny rail to that optics can be mated right up to the action for a solid zero maintaining connection between rifle and optic. Champion tripod front rest and sandbags were used to support the Ruger Precision Rifle during bench testing phase of evaluation in conjunction with bipod.

Various .308Win loadings from Black Hills Ammunition, Federal, Winchester, and Hornady provided the basis of accuracy tests. The Black Hills Match loads tested consisted of 168 grain Match bullets. The Federal chambering was the venerable 168 grain Match load that still serves as the benchmark for performance. 168 grain TAP from Hornady along with Winchester 168 grain Match was also used. The Precision Rifle’s 20 inch barrel produced velocity in the low 2600 feet per second (fps) range with the 168 grain loads. The Precision Rifle’s 20 inch barrel maximizes portability and handling while maintaining .308Win ballistics and terminal performance. As to be expected with quality ammunition, velocity figures within the different loads deviated very little from round to round as witnessed shooting over a RCBS AmmoMaster chronograph. The Precision Rifle produced MOA or smaller groups with several different ammunition brands—an important logistic consideration. The accuracy figures are based on firing five five-round groups and averaging group sizes.

Steel targets were smacked with ease out to 320 yards using field expedient rests at Echo Valley Training Center’s Range #1 stepped berm system. While by no means rivaling a semi-automatic for pure fire power, the detachable magazines were handy to recharge the Precision Rifle after the last empty case was flipped out on the ground. The Precision Rifle’s action was “slick” and smooth as it emerged from the box. The Magpul magazines that arrived with the Ruger Precision were used as well as the recently introduced Brownells’ AR 308 20-round magazine. The Precision’s bolt would function over the Magpul follower when the magazine was empty; however not with the Brownells due to follower configuration. This is not a criticism of either magazines or rifle. Just an observation so that different user’s can explore on other magazines they choose to use. This does not impact use of the rifle as laying cartridges in the raceway to single feed rounds did not work no matter magazine used. It is required to first click the rounds under the magazine’s feed lips for chambering properly.

The Ruger Marksman trigger is a huge part of the phenomenal accuracy to cost ratio factor derived from the Precision Rifle. The Marksman trigger is just as important to accuracy as the Ruger bolt action and quality barrel. A rifle’s trigger is the interface between shooter and rifle and must be right or accuracy will suffer. From the box it measured just below 4 pound pull weight. Ruger Marksman trigger is externally adjustable with a pull weight range of 2.25 to 5.0 pounds. Conveniently, Ruger has stowed the trigger adjustment tool in the bolt shroud with the previously mentioned bolt disassembly tool. This allows the Marksman trigger to be adjusted by the user without having to resort to an armorer. Without going into minutia, the Marksman distinctive “trigger blade” release lever in front of the trigger proper is the secret to maintaining minimal trigger weight, without creep, while keeping the system safe. The “trigger blade” must be activated (i.e. moved rearward into the trigger) before the sear will move firing the cartridge. A sudden drop or impact will not do this, even if the safety is off. The Marksman trigger’s contribution to precise accuracy can not be overemphasized.

In an effort to demonstrate the Ruger Precision Rifle’s flexibility in use, a Yankee Hill Machine Phantom flash suppressor was threaded on. The YHM Phantom flash hider allows for easy mounting of the YHM 7.62 Phantom suppressor. YHM’s Phantom 7.62 Sound Suppressor is a .30caliber suppressor utilizing Mike White’s Sound Technology Inc.’s patented baffle design. The Phantom 7.62 Sound Suppressor is manufactured from Chrome-Moly steel and features a matte black Parkerized finish. Its overall length is 8.5 inches with a diameter of 1.6 inches and weighs 25ounces. Hand tightening is all that is needed with the Phantom Flash Hider to hold the suppressor firmly in place. Conversely the suppressor can easily be removed via hand pressure when no longer needed. The Phantom Flash Hider supports the suppressor in two places helping to ensure bore alignment. A patented gas seal keeps the Phantom Flash Hider threads clean so the suppressor will not bind when removed from a weapon no matter how many rounds are fired.

Some time ago Engel Ballistic Research (EBR) subsonic ammunition was discovered as a primary source of quality sub-sonic ammunition due to the variety of calibers and loadings offered. Another reliable source for .308Win sub-sonic loads is Corbon. The Ruger Precision Rifle combined with YHM suppressor and Engel Ballistic Research or Corbon sub-sonic .308Win loads is eerily efficient out to 100 yards. Furthermore tactical modification of the Precision Rifle into a lowlight/dark role is satisfied by mounting an American Technologies Network ATN PS22 Night Vision device in front of the Leupold scope. This multiuse ability keeps day scope constantly zeroed, yet allows for quick adaptation night use. The PS 22 is attached or detached with no impact on the day optic’s point of aim and parallax is not an issue. Another benefit of the PS 22 is that a scope’s reticle does not need to be illuminated or IR compatible for it to be visible when using the PS 22. This differs from NV products that mount to the rear of the scope. These kinds of uses are outside the realm that most user’s require from a weapon.

The ability to adjust the Ruger MSR stock in a myriad of ways further supports its accuracy potential. Length of pull (LOP), check riser height, even cant of the buttpad is adjustable to user preference. The ability to fold and lock the Ruger MSR stock eases transport. An Eberlestock G2 pack proved a natural companion to the Precision Rifle during T&E. The G2’s combination of being a top loader pack and accessible front panel means that the main compartment is hassle free to access. There’s no digging and wrestling with your pack to free an item–its quick at hand. It’s a great combination. If you carry your weapon on your back, you’re much more agile and effective than if it’s stuck in your hands or on a shoulder sling all of the time; simply no better way to move about in an organized fashion. By having the pack carry the rifle, your hands are free for all of the things you need them for when you are traversing terrain. Further more, Eberlestock makes it so that you can get your weapons off the pack without having to un-strap everything that you’re wearing. Most importantly the pack must be comfortable considering all the time spent with it out in the field. The Gunslinger II (G2) has all these characteristics. It’s a mid-sized pack with a full-width scabbard to better accommodate weapons with larger cross-sections or bulky optics; weapons up to 60 inches long can be accommodated. Eberlestock’s “Control Clips” at the top of the G2’s Backscabbard compartment are used to segregate the scabbard and also to securely hold a rifle. The Control Clips are also used to hold the top cover onto the scabbard locking your gun into the pack. The G2 offers 2,700 cubic inches of space measuring 22 inches high, 10 inches wide, and 8 inches deep. The G2 can be generalized as a Three-Day pack in terms of what it can carry afield. The G2 is waterproof with the 1000d Cordura Nylon material polyurethane coated.

Even though a bolt action and imminently qualified to serve a precision tactical weapon, the Ruger Precision Rifle should not be pigeon holed into solely a sniper rifle role. There many jurisdictions and/or private users that will appreciate its non-assault rifle bolt action persona while maintaining its high capacity capability. Misconstrued prejudices may arise when it comes to Ruger Precision Rifle stemming from elitist sentiments based on price. Some individuals, not to mention industry competitors, will want you to believe that the moderately priced Precision Rifle, $1399 MSRP, must somehow be deficient when compared to rifles costing two to three times more. The Ruger Precision Rifle takes a back seat to no rifle in terms of repeatable accuracy, ergonomics, reliability, trigger, and capacity.

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.

LWRCI is a recognized industry leader in the development and manufacturing of short-stroke piston operating ARs. LWRCI’s entire reason d’être is the short-stroke piston and the improvement it offers over the original gas impingement design – especially when incorporated into short barrel platforms. It is no secret that the AR is not only the best selling civilian and law enforcement rifle in the U.S., but also gaining popularity around the world with the U.S. equipping/training so many armed entities. This has caused many manufacturers to jump on the AR bandwagon in recent years by offering their versions. Of late, the most attention seems to be on “improving” the AR platform via developing piston-driven ARs in lieu of Stoner’s original gas impingement design. Whether or not piston-driven ARs are superior to their gas impingement brethren often generates heated discussion. One thing that is not debatable is the number of manufacturers rushing to create piston-driven ARs even if traditional AR models already exist in their production line-up.

LWRCI offers numerous models ranging from LE/military-only select-fire versions, various barrel lengths/profiles ranging from 7-inch barrel UCIW model to 18-inch barrel M6A3 DMR. Other unique models include the M6A4 IAW that fires from a closed bolt on semiautomatic then goes to open bolt function on automatic fire and then ultimately the 7.62×51/308Win REPR. The REPR is quickly finding favor in U.S. law enforcement and military special operation communities. Another LWRCI model, and the one focused on in this article, is the PSD – Personal Security Detail. The PSD is one of LWRCI’s smallest, dimensionally speaking, contributions to the AR field. A LWRCI PSD upper was obtained for testing in lieu of a complete rifle. The flexibility of the AR platform is hard to beat considering one moment an 8-inch barrel PSD upper is fitted to NFA registered lower – if a civilian or LE – and the next an 18-inch heavy barrel DMR upper is installed if mission dictates it. This does not even get into the myriad of calibers that are coming on line for the AR ranging from 5.7 to .50 Beowolf with many stops in between.

LWRCI literature clearly lays out the thought process behind the development of the PSD. The 8-inch barrel PSD 5.56mm is designed for CQB and personal security detail (PSD) operations. It is best to view the 8-inch barreled PSD through the lens of a PDW or SMG weapon versus a rifle. The 8-inch barrel produces approximately 2,400-2,500 fps velocities when firing 50gr-62gr 5.56mm loadings. The PSD is also available in 6.8 SPC chambering; in fact it was the original chambering in the PSD product line. However, the decision was made to also chamber the PSD in 5.56mm based improvements in the 5.56mm cartridge in terms of bullets and powders. This re-evaluation is based on 5.56mm performance being greater than any pistol caliber combined with the compact dimensions of the LWRCI PSD rivaling a SMG. It only made sense from a business standpoint considering the vast number of individuals, departments, agencies, and units intimately familiar with the 5.56mm round and existing number of magazines/ammunition already in the supply chain.

The PSD utilizes LWRCI’s patented self-regulating, short-stroke gas piston operating system, ensuring reliability in the harshest theaters of operation. LWRCI literature points to several industry leading technological innovations incorporated in the PSD. LWRCI has sought to engineer a complete solution to the deficits found in the direct impingement AR family of rifles and carbines and was an early innovator in the AR gas-piston surge. The principal improvement comes from eliminating the venting of hot, carbon-laden gases into the receiver and bolt carrier group. This reduces the cleaning requirements associated with direct gas impingement ARs. It also means the bolt carrier group and associated springs are not subjected to the searing heat of the tapped gasses; this being one of the major causes of small parts failure. The LWRCI PSD utilizes cold hammer forged barrels made out of 41V45 steel alloy and treated with NiCorr surface conversion technology. NiCorr surface conversion has proved more lubricious, harder wearing, more heat and corrosion resistant than the hard chrome-lining normally used in a service rifles’ bore. LWRCI advertises its barrels as being able to handle 20,000 rounds before replacement, as compared to 6,000-10,000 rounds with standard chrome lined barrels. The bolt carrier of the PSD is coated with a proprietary nickel coating that nearly eliminates corrosion while providing greatly increased lubricity. This coating provides permanent lubrication to the moving parts and is similar to that being used by the U.S. Army Research Lab and USSOCOM to extend the service life of their weapons systems.

The PSD’s ARM-R forend’s top rail is easily removable and reinstalled without effecting zero of any sights or target designators. Cleaning methods for the LWRCI are familiar to anyone with experience with the AR-15 with the operating rod mechanism easily accessed thanks to ARM-R design. The ARM-R rail allows for mission specific configuration with lights, lasers, target designators, and other items. As benefiting a rifle in the PSD’s price range and intended LE and military audience, the PSD comes standard with folding BUIS open sights that proved able to co-witness with a variety of optics mounted on the PSD. The PSD upper installed on a lower weighs slightly over 6 pounds and has an overall length of 24.5 inches with LMT SOPMOD stock collapsed and approximately 28 inches extended. The LMT SOPMOD is a favored stock type and the type affixed to lower mated with LWRCI PSD upper for a large portion of this T&E. The PSD’s 8-inch barrel features 1:7 twist and comes with an A2 style flash hider. The 8-inch barrel maximizes portability and handling while maintaining a ballistics and terminal performance superior to any pistol caliber carbine or SMG.

The key with the LWRCI PSD is having an 8-inch barreled AR that works at the same reliability level as longer barrel ARs. This is where the LWRCI short-stroke piston comes into play. Instinctually, piston driven ARs appeal too many by the very fact that hot gases and powder residue is not dumped into the action as in the original direct impingement (DI) design. Hands on experience of LWRCI bolt carrier being handled soon after long strings of fire and merely wiped down compared to their DI cousins reinforces this. The ability of the gas piston ARs to operate with barrel lengths below the generally accepted 14-inch barrel threshold of DI ARs reliability adds further legitimacy to the piston ARs. Do not take this as lampooning of the gas impingement ARs. The DI rifles are more robust than most give them credit for and sub-14 inch barreled rifles are possible with attention to detail by the manufacturer in terms of gas port sizes and timing of the ejection process.

LWRCI utilizes a piston design made up of three components. A piston cup fits over the gas plug located at the front of the PSD handguard with an intermediate rod placed between the piston cup and operating rod that acts on the bolt carrier group. The LWRCI push-rod system is self cleaning in that any excess gas is vented out of the handguard just behind the gas block. The gas cup has grooves that act as scrapers as the action is worked to prevent carbon build up in the gas cup. The rear of the gas-piston rod is what smacks against the bolt assembly’s integral strike plate operating the action. LWRCI’s pioneering work with the AR piston system has led to the use of an integral strike plate in lieu of a staked version. This is based on concerns of metal fatigue and not wanting to take the chance of a staked strike plate failing. Along these same lines the LWRCI’s bolt body features radial grooves that serve multiple functions; such as anti-tilt for the bolt assembly along with providing a certain amount of built-in tolerance against any debris that may find its way into the LWRCI’s action and buffer tube area. LWRCI’s short-stroke piston use of a “tappet” system to impart force to the piston driving the bolt carrier to the rear minimizes heat build up not only in the weapon’s action, but also along the weapon’s forend due to gas being confined to the gas plug/piston cup located behind the gas block; thus preventing hot gas from transmitting down the length of a gas tube ala direct impingement or long-stroke operating method.

C.R. Newlin, Echo Valley Training Center owner, generously allowed access to his select-fire AR lower for testing with the LWRCI PSD upper supplementing a registered semi-only lower already on hand. Range testing commenced with functionality test consisting of dumping multiple magazines at several targets in rapid fashion once sight zeros were verified. Any fighting rifle must be reliable to be worthy of further consideration. The importance of quality magazines can not be overstated in terms of impacting a weapon’s reliability. The majority of malfunctions in a select fire, or even semi-auto rifle, can be traced to a faulty magazine. Brownells’ AR magazines are primarily used for most T&Es for this reason, though random magazines are mixed into testing at times. The LWRCI’s short-stroke gas piston operating rod system proved its worth in keeping the bolt carrier group cooler and cleaner compared to direct impingement AR rifles. While not trying to be unrealistic or overly harsh, the LWRCI PSD was exposed to multiple magazine dumps at various times of the T&E. The method was not mindless ammunition wasting, but rather wanting to confirm beyond a doubt that the PSD delivered as advertised under the most extreme circumstances of operational functioning. It was quickly noticed how little heat was transmitted not only to the PSD’s action, but also into the PSD’s quad rail forend with shooters able to grip the weapon without resorting to gloves or installing a vertical forward grip. Anyone with experience with AKs or direct impingement ARs know how fast forends can heat up with only a few magazines worth fire.

It was decided to take full advantage of the PSD’s flattop upper by accessing multiple optics for use during testing. A Trijicon RX30 Reflex was mounted on the PSD with it sharing time with a Leupold Prismatic. A Hi-Lux/Leatherwood Optics CMR 14×24 was also employed to ascertain the PSD’s accuracy potential via 4x magnification capability. The CMR scope was designed for when a shooting situation gets up close and personal. The CMR (Close Medium Range) has 1x-4x magnification based on a compact 30 mm tube. The relatively short 30 mm tube scope does not add a lot of weight to the rifle, and thanks to the large diameter of the scope tube, it lets in a lot of light for a bright target image. Hi-Lux/Leatherwood literature points out, “…an extremely practical circular reticle that aids in quick target acquisition by drawing the attention of the shooter’s eye to the center of the scope. Along these same lines, to insure that the target is fully visible, the reticle has only a horizontal crosshair, with a partial vertical lower crosshair. The upper half of this reticle leaves the scope clean and uncluttered. Plus, the lower crosshair features short bar aiming points calibrated for standard .223 and .308 service ammo, which are very precise out to 600 meters. The center dot and the small circle of the reticle are available with either green or red illumination.” It was discovered that the PSD’s rear flip-up sight had to be removed to provide clearance for the CMR to mount properly, which would be a negative for many considering the PSD’s likely CQB role in the field.

The optic types intended to be left on the LWRCI PSD after accuracy testing would be the Trijicon RX30 Reflex or Leupold Prismatic; though some may be inclined to leave the Hi-Lux/Leatherwood CMR mounted. The Trijicon RX30 and Leupold Prismatic sight offer the capability to engage multiple targets in rapid sequence compared to open sights, while at the same time providing adequate accuracy out to a couple hundred yards. As many “maturing” shooters can attest to, a single focus plane is easier to shoot accurately than coordinating front and rear sights. The 5.56/.223’s flat trajectory aids in making hits out to 250 yards without having to compensate excessively for bullet drop even with the short 8-inch barrel.

A 150 yard zero provides for +2 inches at 100 yards, -5 inch at 200 yards, and -13 inches at 250yds.

The PSD was evaluated at Echo Valley Training Center (EVTC). EVTC is fast becoming a major provider of training on the East Coast with multiple organizations conducting courses onsite. The private facility has multiple 100 yard bermed enclosed bays capable of handling numerous students conducting “square” range drills or more dynamic/fluid types of training. In conjunction with the individual training bays, Echo Valley Training Center features multi-stepped target berms that are strewn with reactive steel MGM targets, fluid drained automobiles, and moving targets at ranges varying from 150 yards out to 350 yards.

Ammunition tested with the PSD was a combination of Black Hills Ammunition 55gr FMJ and 50gr TSX, Winchester Ammunition 55gr FMJ and Federal Premium Law Enforcement 55gr Triple Shok and 62gr Bonded SP loads. Loads evaluated chronographed between 2,400-2,500 fps; which was a pleasant surprise considering the short PSD barrel. The PSD kept all loads tested at 1 inch or better at 50 yards with the Federal Premium 55gr Triple Shok and Black Hills 50gr TSX producing near MOA groups out to 200yds. Overall, the accuracy level was more than acceptable considering the barrel’s profile. Most bulk range firing utilized the Winchester and Black Hills Ammunition 55gr FMJ. Ammunition such as the Black Hills 50gr TSX and Federal 55gr Triple Shok and 62gr Bonded loads elevate 5.56mm terminal ballistic performance and barrier penetration across the board; especially in short barreled rifles such as the PSD.

AR ergonomics are hard to beat even on a full size AR with the compact PSD even handier and easier to wield in tight quarters. Drills moving around barricades and training evolutions involving firing and evacuating from vehicles clearly bore this out. A short barrel rifle like the LWRCI PSD is what individuals will choose to work with in such an environment where the trade off in size is worth any loss in bullet performance due to reduced velocity. Prior training experiences with Suarez International, Tactical Response, and Storm Mountain assisted in providing a baseline foundation of what qualities are desirable in a fighting rifle along with proofing ancillary gear such as BlackHawk chest rig for carrying magazines and BlackHawk single-point sling in case the PSD needs to be slung freeing up use of both hands. The PSD’s performance is superior to any SMG and it does not take a backseat to full-size rifles in the sub-200 yard arena, which is what was what the PSD was designed for by LWRCI.
