SSS.6.157- Surefire SOCOM762-MINI2 and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle (Free Version)

The Surefire SOCOM762-MINI2 is a compact 30 caliber machine gun rated rifle silencer that possesses reduced sound signature suppression performance compared with many larger 7.62 silencers on the market, while possessing significantly reduced back pressure. The silencer may also be used on 5.56 weapon platforms; relative to dedicated 5.56 silencers, it may be considered full-size.  The 762-MINI2 is identical in size to the 556-RC2, but exhibits significantly lower performance on 5.56 systems.

In this review, the Surefire SOCOM762-MINI2 performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a commonly fielded gas-operated rifle, which is an incredibly difficult task. How would the Surefire SOCOM762-MINI2 perform on your MK18 with a 10.3-in barrel with both the 3-Prong and WARCOMP mounts? How does Surefire Total Signature Reduction technology performance scale with length, bore diameter, and baffle quantity? PEW Science Member case study included!

SSS.6.152 - Research Supplement: Surefire RC2 vs. RC3 - What Changed? The Quietest 5.56 Rifle Silencers - Taming the MK18, Part 5 (Article Preview)

Both Surefire SOCOM556-RC2 and RC3 systems are evaluated in this members-only Research Supplement to examine relative first round and overall sound signature suppression performance characteristics. These silencers were selected for comparison due to their similar mounting methods, with different design intents; the high flow rate (low back pressure) of the updated RC3 series, in contrast with the legacy RC2 design, results in different sound suppression performance at the muzzle and shooter’s ear on the standard PEW Science MK18 test host weapon system.

Commentary on the reason(s) for the design changes in the SOCOM556-RC3 from the SOCOM556-RC2 are provided. Following that commentary is technical discussion regarding the physical differences between the SOCOM556-RC2 and SOCOM556-RC3 rifle silencer systems that Surefire implemented in order to address the desired performance changes. Finally, the efficacy of the changes are discussed, followed by high fidelity signature analysis for PEW Science Members that highlights the changes in performance and resulting actionable detailed signature severity data for end users, to complement the PEW Science Suppression Ratings already presented.

SSS.6.128 - Surefire SOCOM556-RC2 and the M4A1 Mid-Gas 5.56x45mm 14.5-in Barrel Automatic AR15 Rifle (Free Version)

The Surefire SOCOM556-RC2 is a full-size 5.56mm machine gun rated rifle silencer that possesses competitive sound signature suppression performance with many silencers on the market, while possessing reduced back pressure compared to some designs. Users should note that full-size 5.56mm rifle silencers are often smaller than their full-size 7.62mm (.30) counterparts. The SOCOM556-RC2 was designed for the 10.3-in MK18 weapon system.

In this review, the Surefire SOCOM556-RC2 performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a commonly fielded gas-operated rifle, which is an incredibly difficult task. How would the Surefire SOCOM556-RC2 perform on your M4 with a 14.5-in barrel?

SSS.6.105 - Thunder Beast Dominus-SR and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle (Free Version)

The Thunder Beast Dominus-SR is a mid-size and lightweight 30 caliber machine gun rated rifle silencer. As a 5.56mm machine gun rated rifle silencer, it may be considered full-size. The Dominus-SR reportedly exhibits significant durability for a titanium rifle silencer, through the use of its engineered sacrificial steel muzzle brake mount. The signature suppression performance of the silencer on the short-barrel MK18 is not as balanced as some other tested rifle silencers, due to its flow rate and other signature factors, examined in this test report.

In this review, the Dominus-SR performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a short barrel gas-operated rifle, which is an incredibly difficult task. How would the Thunder Beast Dominus-SR perform on your AR15 short barrel rifle? Bonus Surefire SOCOM556-RC2 and TBAC Dominus-SR detailed comparative case study included for Members!

SSS.6.103 - Research Supplement: The Quietest 5.56 SBR Silencers - Taming the MK18, Part 4 - HUXWRX vs. Otter Creek Labs vs. CGS vs. Surefire (Article Preview)

Five silencers evaluated by PEW Science are included in this members-only Research Supplement to examine relative First Round Pop (FRP) and overall sound signature suppression performance characteristics. The five silencers were selected for their high average sound suppression performance at the muzzle or shooter’s ear on the standard PEW Science MK18 test host weapon system. All five silencers induce differing hearing damage risk to the shooter and bystanders on this weapon platform, on average.

This research supplement is intended to provide more information to PEW Science members with regard to specific sound signature characteristics of the tested configurations in the aforementioned reviews, and to help frame objective loudness comparisons between five silencer configurations exhibiting differing sound suppression performance on the MK18 weapon system. Both the FRP and average sound signature suppression regimes are examined. This supplement is part of ongoing PEW Science small arm weapon system sound signature research.
