Ruger Silent-SR Series Suppressors

Sturm, Ruger & Co., Inc. is the quintessential example of American capitalism at its best. The company was founded with a meager $50,000 investment by William B. Ruger and Alexander M. Sturm in a small, rented machine shop in Southport, Connecticut in 1949 for the purpose of manufacturing firearms. At that time, there were serious doubts within the industry with insider experts saying that “it can’t be done,” and that the entire industry was in decline. It was assumed that the large established name gun makers would continue to dominate the market.

What the industry didn’t count on was that this new company was guided by a number of innovative concepts, not the least of which was William B. Ruger’s desire to build each product “to a standard so that I would want one even if it was made by our competitors.” These basic principles of innovation, quality and value have earned the company the position of pre-eminence in the firearms industry over the past 68 years. Ruger, which is one of only two firearms manufacturers traded on the New York Stock Exchange, produces millions of firearms each year for hunting, target shooting, collecting, self-defense, law enforcement and government agencies.

Ruger’s first product was the Ruger Standard pistol in .22LR. With some design innovations inspired by the Japanese Nambu and cosmetics/ergonomics of the German Luger, it became wildly popular—it was comfortable to hold and shoot. A retail price in the 1950s of $37.50 (representing fewer than 40 hours minimum wage effort), decent accuracy and good reliability were winning factors. Designed with manufacturing economy in the forefront, it had a 4.75-inch barrel and fixed sights. Many a bullseye match shooter had one in the bottom of his bag to permit finishing a match when his finely tuned target gun malfunctioned. It was also found tossed in the bottom of fishermen’s tackle boxes. Its popularity (and that of the 10 /22 rifle) started an ever growing industry of accessory makers.

Ruger is no stranger to the National Firearms Act weapons, having developed and built several machine guns. In the late 1980s Ruger purchased the rights to the UZI and what became the MP9 from Uziel Gal, its designer. In 1995, Ruger introduced its MP9 9mm submachine gun. Although recognized as an improved UZI, the weapon never became popular or even well known. Bill Ruger held the belief that civilians should not have access to machine guns and established the company policy that no Ruger machine guns would ever be sold to civilians, including Class 3 firearms dealers. The market was to be domestic law enforcement and international military. However, noted in the company’s law enforcement catalog, marketing to law enforcement requires personal demonstrations by local Class 3 firearm dealers. The MP9 was discontinued in 1996. Ruger’s other venture into the machine gun market was a variant of their 1973 Mini-14, the AC-556, which looked exactly like the Mini-14 but had a selector switch (semi, burst, full-auto) at the receiver right rear. The standard AC-556 was offered in both blued and stainless versions as well as a shorter weapon with a folding stock and 13-inch barrel (AC-556K or AC-556F) in blue or stainless. With marginal sales (although far better than the MP9), production was discontinued in 1999 and support terminated 10 years later. Until William B. Ruger’s death in 2002, no Ruger machine guns were sold to civilians. The civilian marketplace was through sale of police trade-ins.

Part of Ruger’s success has been through good market research, outstanding engineering and production of innovative products without significant bureaucratic impediments to slow down development. Part has been financing through reinvestment of profits rather than using traditional debt structure. And part has been by doing manufacturing in-house. Ruger’s Pinetree Casting (Nashua, NH) is one of the foremost investment casting facilities, and in addition to many Ruger weapon receivers, does casting for golf clubs. In 2014, the company purchased Megamet Solid Metals Inc., based in St. Louis, Missouri, to add metal injection molding (MIM) casting capability not only for increased production capacity, but to markedly reduce development time for new products. Unlike many of its competitors, Ruger has not acquired related companies, either competitors or accessory makers.

The use of silencers has become mainstream over the past 4 to 5 years, a fact not overlooked by Ruger. Although their 10 /22 rifles sold in the international market were routinely threaded 1 / 2-20 for European rimfire silencers, it wasn’t until several years ago that domestic Ruger .22 rifles and pistols came threaded 1 /2-28 for the US market. Ruger looked at possible acquisition of a silencer company but after due diligence decided to start building suppressors in-house at their New Hampshire facility.

Approximately a year ago, Ruger introduced two sound suppressors designed for rimfire cartridges: the “Silent-SR” thread mounting muzzle suppressor and the “Silent-SR ISB” integrally suppressed barrel for their take-down 10 /22 rifle.

Both suppressors are attractively packaged in boxes with a fitted foam insert. Any necessary tools are included: a cast composite spanner wrench for removing the endcaps of the Silent-SR and a hex wrench for disassembling the integral Silent-SR ISB. All suppressors are supplied with a 12-page, well written and profusely illustrated manual that covers legal and safety aspects, specifications, attachment to the host weapon, use, disassembly and cleaning instructions. Disassembly for cleaning is simple, and it is virtually impossible to reassemble incorrectly. Both are finished in black Cerakote.

Testing Protocols

The first question posed by most users relates to sound performance since that is the stated goal of a sound suppressor. There are a number of ways to evaluate sound levels, starting perhaps with Mitch WerBell of Sionics fame in the 1970s where he lined up the office staff and shot two different suppressors behind their backs asking which was quieter. While this has merit in distinguishing suppressed from non-suppressed weapons, subtle differences are distorted by the individual hearing damage of different observers.

A more objective method is to use sound measuring equipment that meets the requirements of MIL-STD-1474D. Not all sound meters are capable of accurately measuring the short peaks of firearm sounds, and even some industrial precision meters do not have the necessary peak detector. There are two classic field portable sound meters that meet all the requirements of MIL-STD-1474D: the B&K 2209 and the Larson-Davis 800B with their appropriate ¼-inch pressure microphones. Originally costing in the $5,000 range, both are currently out of production but are frequently available at reasonable cost. Factory service and recertification services are still available. For testing both Ruger suppressors, two of the L-D 800B meters were used, both of which were recertified by Larson-Davis 4 months prior to this test.

MIL-STD calls for a number of measurement locations. For the purposes of the most meaningful and familiar results, sound levels were measured simultaneously at the standard Reference Location (1.6 meters above grass, 1 meter left of the muzzle 90O to bore axis) and at a simulation of the shooter’s left ear (SLE). The Reference Location gives an indication of how the target or down range observer will perceive the gunshot, and the SLE will give one of the better indications as to potential hearing damage. While some advocate using the shooter’s right ear, close contact with a rifle stock confuses weapon action noise with muzzle blast reduction. The simulated SLE positioning of the microphone is 8 centimeters rearward of the back of the receiver (70 centimeters in the case of a handgun) and 18 centimeters left of the bore axis. By measuring both locations simultaneously for each shot, variations in individual rounds are minimized.

For each weapon-suppressor combination, three rounds were fired non-suppressed, and the results averaged. This was followed by a five-round string with the results averaged. It has been found that this number of rounds is statistically significant. For each location, the averages and reduction are noted. In addition, first round pop is calculated by subtracting the average of the last four rounds from the first round. First round pop is caused by a secondary detonation of partially burned powder particles encountering oxygen in the suppressor. MIL-STD permits the use of weighting scales. For a number of years dating back into the 1970s, A-weighting was used. In recent years, a number of manufacturers have changed to C-weighting, which is more accurate for the sound levels encountered with firearms.

Both OSHA and MIL-STD-1474D state that hearing protection is required for short duration peak sound levels greater than 140 dB at the shooter’s ear.

A second item of concern in evaluating a suppressor is whether there is any degradation in accuracy (group size) when the suppressor is mounted. There is often a shift in point of impact which can be corrected by sight adjustment. Rifles were used in a solid rest (Lead Sled) for group size measurements both with and without the suppressor at a range of 40 yards.

For handguns, high speed video was performed looking for excessive yaw or tumbling with the suppressor in place. Frame rate was 5,000 frames/second with a shutter speed of 30 microseconds to provide stop action of the bullet in flight during the first 2 feet of travel. The high-speed camera used was a monochrome Olympus iSpeed FS.

A third concern primarily of military importance is night-time recognition of the shooter’s location from flash or heat signature visualization. Because these suppressors are designed only for rimfire, flash signature was evaluated using high-speed video and only when mounted on the MK-II pistol (generally the worst case scenario).

With either suppressor, it is necessary to utilize standard velocity or subsonic .22LR ammunition to avoid the ballistic crack found with high-velocity ammunition. This crack has been measured with CCI Mini-Mag ammunition at 142 dB 1 meter to the side of the bullet flight path. In the case of .17HMR or .22 Magnum ammunition, the ballistic crack of the supersonic projectile is acceptable, and live targets are confused because the suppressor masks the origin of the shot.

Test Conditions

November 4, 2017, was a bright, sunny fall day in Boise, Idaho. The temperature was a chilly 50F with a relative humidity of 37% and a station pressure of 686 mmHg. Wind gusts were less than 3 miles per hour. The speed of sound calculated to 1,107 feet/second.

The ammunition chosen for testing was CCI Standard Velocity .22LR with the 40 grain bullet. This was chosen because it is commonly available, accurate and remains subsonic in almost any barrel length chambered for .22LR.

The Silent-SR thread-mounting suppressor was tested on two weapons. One was a Ruger MK-2 pistol with a bull barrel shortened to 4.5 inches and mounted in a Ransom Rest. The other was a Ruger 77 /22 with the barrel shortened to 16 inches. The Silent-SR ISB was tested on a Ruger 10 / 22-TD, its normal host weapon.

Silent-SR Thread-Mount Suppressor

The Silent-SR is packaged inside a black ballistic nylon pouch with a convenient belt loop. The suppressor length is 5.4 inches, outside diameter is 1.05 inches, and the weight is 6.4 ounces. It is rated for .22 Magnum and .17HMR in addition to fully automatic .22LR. The length of the threads in the mount is .43 inches, standard for the industry, with a .12-inch thread relief in the mount for safe use with barrels not having a thread relief. The threaded mount is a part of the entrance chamber. There are a total of six baffles (type 17-4 stainless steel), all having a bore aperture of .25 inch. The front end cap functions as a seventh baffle. The rear (blast) baffle is symmetric, and the remaining baffles have significant asymmetry. All baffles have a general conical shape with integral spaces. The tight bore aperture requires barrel threads with a true 90O shoulder for alignment.

Sound measurement levels were obtained on both a Ruger MK-II pistol (4.5-inch barrel) and a Ruger 77 /22?bolt action rifle (16-inch barrel). Both of these weapons are used routinely by the author for rimfire sound measurements. Sound performance was excellent as shown in Table 1 with the absolute sound level at the reference location of 120 dB on the MK-II and 116.7 dB on the 77 /22 rifle.

It is important to remember that there will be day-to-day variations in the sound levels that appear to vary with location, humidity and ambient air temperature. Measurements made in a coastal location do not always correlate with those made in a high desert location such as Boise, Idaho. As a rule, five-round strings are statistically valid (standard deviation <1.5), which is why the tables include the standard deviation for the five suppressed measurements. The one exception was measurement at the reference location where the 8 dB first round pop increased the standard deviation. However, calculating excluding the first round resulted in an average of 118.4 dB and a standard deviation of 1.1, which is in line with all other measurements.

Although what is normally asked is the reduction, the more important measurement is the absolute sound level, both for far field and for hearing risk evaluation. First round pop can be eliminated with either an inert atmosphere (nitrogen, carbon dioxide, etc.) or a tiny amount of oil or grease in the entrance chamber. Absolute sound levels for the rifle are considerably lower than for the pistol, but the degree of reduction is significantly less. This is simply because the non-suppressed level on the rifle is significantly lower than on the pistol.

Accuracy and bullet stability were checked differently on the two weapons. With the Silent-SR mounted on the 77 / 22 bolt action rifle, a target was shot with and without the suppressor at a range of 40 yards. Adding the suppressor moved the point of impact down .176 inches (.421 MOA) but tightened the group from .795 inches (1.9 MOA) to .688 inches (1.64 MOA) with three shots touching. See Target 1.

A check of bullet stability on the MK-II pistol was considered difficult lacking optical sights. Instead, a high-speed video (5,000 frames/second) was performed. Lighting was difficult lacking bright sunlight, so two compromises were accepted: 1) a shutter speed of 30 microseconds (instead of the preferable 2 microseconds and 2) image enhancement (which decreased resolution). Eleven consecutive frames showed the bullet in the first 24 inches forward from the end of the suppressor. These 11 photos were superimposed to show the progress of the bullet traversing this distance as shown in the photo. Starting at the 20-inch region, there is slight yaw, which is normal as the bullet transitions from rotating about its physical center to rotating about its center of gravity. There was no visible flash detected.

The manufacturer’s suggested list price for the Ruger Silent-SR thread mounting suppressor (model 19000) is $449.

Silent-SR ISB for the Takedown 10/ 22-TD

The Silent-SR ISB is a complete replacement barrel with integral suppressor assembly for the Ruger 10 / 22-TD rifle. Unlike similar offerings, the Ruger suppressor includes all hardware and the forend composite handguard. The suppressed barrel is 16.12 inches long, making it .5 inch shorter than the standard barrel, and weighs 41.9 ounces as contrasted to the 30.7 ounces of the standard barrel. The suppressed barrel bears a resemblance to the over/under double-barreled shotgun with a width of .925 inches and height of 1.52 inches. The bore aperture throughout the baffle stack is .280 inch.

The suppressed barrel is alloy steel and 10.62 inches long. The aluminum suppressor outer housing has been permanently attached to this barrel to make the overall length in compliance with BATF regulations. The front end cap and baffle stack are easily removed by loosening the assembly bolt, a process well described in the manual. The blast baffle is symmetric, and the remaining six are significantly asymmetrical. All are type 17-4 stainless steel.

Sound measurements were made using the same host 10 / 22-TD receiver and comparing the original non-suppressed barrel with the Silent-SR ICP integrally suppressed barrel. The results are shown in Table 2. The suppressed barrel measured an impressive 114.7 dB at the reference location, which is only approximately 4 dB louder than the hammer falling on a spent cartridge case.

Accuracy testing was performed in the same manner as for the thread mounting suppressor on the rifle. The range was 40 yards, and the weapon was shot using the Lead Sled rest. A fixed 10x scope was attached to the Weaver base supplied with the rifle. Five shot groups were fired with both the standard and suppressed barrels. The target is shown in Target 2. The suppressed barrel tightened the group from 2.9 inches (6.92 MOA) to 2.05 inches (4.9 MOA) and dropped the group center by .77 inches (1.84 MOA).

The group sizes, both suppressed and non-suppressed, were considerably larger than with the thread-mounted suppressor on the 77 /22. There are several reasons for this, not the least of which is a re-worked 2.5-pound honed trigger on the 77 /22 with no over-travel as compared to a rough 6-pound trigger on the 10 /22-TD with significant over-travel.

The second issue is with barrel lockup on take-down weapons. The 10 / 22-TD tensioning ring has to be adjusted when one barrel is replaced with another. The tension at lockup is not totally consistent, and there is the potential for almost imperceptible flex at the barrel/receiver joint. Even simple removal and replacement of the same barrel can cause a minor point of impact shift. The most accurate way to mount an optic on a take-down rifle is to mount it on the barrel rather than the receiver. In contrast, the 77 /22 barrel is mounted in a far more rigid manner using a V-block and torqued mounting screws.

The manufacturer’s suggested list price for the Ruger 10 /22-TD Silent-SR integral suppressed barrel (model 19001) is $629.

Comments

Both suppressors have their strong points, including excellent sound performance, tightening of the shot groups and obvious quality. The Silent-SR ISB for the 10 /22 Takedown is definitely the more compact weapon due to the requirement for a 16-inch minimum barrel length. What would be a worthwhile improvement to the integral Silent-SR ISB would be to supply a rail contoured to the .920 diameter of the steel portion of the barrel for barrel mounting of an optical sight. The thread mounting Silent-SR has the advantage of a wide variety of weapon platforms and the strength to hold up to multiple rimfire cartridges. While both are outstanding, the author has a bias for thread mounting suppressors because of their versatility.

The new and improved SureFire SOCOM556-RC2 Fast-Attach® suppressor is the most advanced 5.56 mm rifle suppressor ever made. Compact and lightweight, our SOCOM suppressor was selected for the Mk18 and M4 by US Special Operations Command as first among all competitors in the most extensive and rigorous suppressor evaluation in history. This test covered all aspects of suppressor performance, and SureFire beat every other entry. It has also received the USSOCOM official safety verification in support of fielding. Constructed of advanced high-temperature alloys and stainless steel, the SOCOM556-RC2 features a more advanced internal venting to reduce back pressure, reducing the suppressed cyclic rate and gas blowback on the operator. The new design also includes an integrated blast shield in the back section that increases durability. The patent-pending front-plate design along with proprietary improvement in gas-flow dynamics nearly eliminates first-round flash, a true technological breakthrough in this area. It also attenuates noise and dust signatures to an unprecedented degree. A new indexing system and computer controlled welding means this suppressor securely mounts to a SureFire muzzle brake or flash hider even more solidly than our previous models, and is easier to remove after extended firing since the index tab is in a low carbon-buildup area. Like all SureFire Fast-Attach models the SOCOM556-RC2 produces minimal, consistent shift in point of impact compared with the unsuppressed weapon.

The SIG M400 has been introduced for consumers who prefer the direct impingement gas system and have an inventory of parts and accessories for the original M4-style carbine. Built with SIG Sauer quality and reliability, the SIG M400 is also an exceptional value for those seeking an AR-platform rifle. To increase accuracy over mil-spec carbines, the SIG M400 features a tensioning device designed into the lower receiver that ensures a tight lockup and eliminates accuracy-robbing play between the upper and lower receivers. The lower receiver has all the same features as the SIG 516 such as an ambidextrous magazine release and rear quick-detach sling mount. Both receivers are machined from 7075-T6 aircraft-grade aluminum forgings and coated with a durable phosphate finish. The upper receiver features an integrated Mil-Std 1913 accessory top rail for mounting optics and accepts most M16/AR-15-style furniture. A six-position collapsible polymer stock offers adjustability to fit all shooters. An enhanced version of the SIG M400 features all Magpul furniture.

Leatherwood/Hi-Lux Announces new 8X USMC Sniper Scope

One of the most recognized names in military sniping during the Vietnam conflict was Marine Corps marksman Carlos Hathcock. During his two tours, he was credited with 93 confirmed kills. The rifle he relied on for very precise long range shot placement was a Model 70 Winchester, of .30-06 caliber, topped with an 8x Unertl scope. Scopes of this design, with micrometer click external adjustment, were once favored by long range precision shooters, and quite a few different scope manufacturers offered very similar models. Today, an original USMC marked scope in mint condition can sell for as much as $5,000 to $6,000. With the current interest in shooting and competing with vintage style sniper rifles, just a working standard model scope in very good condition can still bring $2,000 or more. Leatherwood/Hi-Lux Optics is now adding an 8X USMC-SNIPER model to its Wm. Malcolm line of vintage style riflescopes. Not only will this scope match the originals for extremely precise adjustment of windage and elevation, the new made scope also offers the advantages of modern lens making, with fully multi-coated lens surfaces for maximum light transmission. This scope offers the brightest, clearest, and sharpest optics ever in a riflescope of this design. The scope will be marked with the Wm. Malcolm name over the USMC-SNIPER model designation, and each will be serial numbered – as were the original USMC models. The Marine Corps utilized this style of scope on sniper rifles during WWII and Korea. The new Wm. Malcolm 8X USMC-SNIPER captures the look, the precision and the accuracy capable with riflescopes of this type. At the $549 suggested retail price, it is far more affordable than a serviceable original from the 1940s, or even the 1970s when they were still in production. Like all Leatherwood/Hi-Lux Optics, the Wm. Malcolm USMC-SNIPER model comes backed with a limited lifetime warranty. You can contact them at Leatherwood/Hi-Lux Optics, Dept. SAR, 3135 Kashiwa Street, Torrance, CA 90506. Phone: (310) 257-8142. Fax: (310) 257-8096. Website: www.hi-luxoptics.com.

New High Tech Suppressors From Thompson Machine

Thompson Machine’s Poseidon series of sound suppressors represent something truly new on the sound suppressor market. While most 9mm and .45 ACP pistol suppressors are 7 + inches long and weigh in at around 10 ounces or more, Thompson Machine’s Poseidon 9mm is a scant 4.25” in length and weighs a barely-there 3.5oz. Designed to suppress your sidearm to a hearing-safe level without significantly affecting its handling characteristics, the Poseidon series of suppressors uses artificial environment technology combined with a cutting edge baffle design to provide shocking efficiency and sound suppression in an impossibly small package. Perhaps most amazingly, the Poseidon .45 which quiets the bark of the mighty and venerable .45 ACP cartridge is only 4.5 inches long and weighs less than 5oz. In addition to their line of micro-suppressors (which includes a 4-inch .22 LR suppressor called the Wasp for rimfire enthusiasts), Thompson Machine manufactures a full range of suppressors, from 4 different models of .22 LR muzzle suppressor up to 5.56 and .30 cal. centerfire rifle suppressors. Everything that Thompson Machine makes is easily disassemble-able for cleaning and user service, which is also a feature that sets their suppressors apart.

Israeli Special Forces DVD from Mako Defense

With the release of its DVD titled Israeli Special Forces Training: Counter Terror Carbine, Mako Defense now offers video training information that enables anyone to understand and apply the unique advantages of the Israeli Method of fighting with a tactical carbine. This DVD parallels the live Mako Defense courses currently being offered across America. It gives viewers the opportunity to learn and practice techniques that can save their lives and the lives of innocent victims. The Israeli Method of fighting revolves around the concept of using speed and accuracy to quickly neutralize any threat, while protecting bystanders. As presented by Mako Defense, it is designed to give U.S. law enforcement officers the most effective methods for working alone, with a partner, or in a team; to give military combatants the skills required for a successful mission; and enable civilians to become highly competent in every aspect of using their tactical rifles for home defense as well as shooting sports. Mako Defense Training – live and on DVD – is fast-paced, exciting and readily understood by everyone. Even in live classes where law enforcement officers, military personnel and civilians often train together, each person is able to learn at their own pace and within their different physical capabilities. DVD training can be repeated and reviewed endlessly at no additional cost, to perfect the Israeli Method techniques shown. Each technique is presented, demonstrated, and then broken down, while being filmed from multiple angles, before being demonstrated at speed in live fire drills. Viewers can experience dry-fire practice of the methods taught in the DVD course. Mako Defense instructors are experienced warriors who have seen extensive action as members of Israel’s most elite special operations units. They are certified as instructors by the Israeli government and teach the Israeli Method on a daily basis in Israel and around the world. The lead instructor featured in these videos has responded to most hostage situations in Israel from 1995 to the making of the video. Instructors were also members of the leading Israeli Police counter-terror and hostage rescue team. They have completed years of service in both a military unit that is the equivalent of the U.S. Delta Force, and in an undercover unit that specializes in the abduction or elimination of high-level terrorists.
