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

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.6.73 - Surefire SOCOM762-RC2 and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle

The Surefire SOCOM762-RC2 is a full-size 30 caliber machine gun rated rifle silencer that possesses competitive sound signature suppression performance in the supersonic flow regime with 7.62x51mm cartridges, while also possessing significantly reduced back pressure. The performance of the SOCOM762-RC2 in short barrel 5.56x45mm applications is reduced.

In this review, the SOCOM762-RC2 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 SOCOM762-RC2 perform, with a WARCOMP or Flash Hider mount, on your AR15 short barrel rifle?

SSS.6.52 - Surefire SOCOM556-RC2 and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle

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.

In this review, the SOCOM556-RC2 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 SOCOM556-RC2 perform, with a WARCOMP or Flash Hider mount, on your AR15 short barrel rifle?

SSS.6.26 - Surefire SOCOM762-RC2 and the Savage Model 10 PC .308

The Surefire SOCOM762-RC2 is a full-size 30 caliber machine gun rated rifle silencer that possesses competitive sound signature suppression performance with many silencers on the market, while also possessing significantly reduced back pressure. The performance of the SOCOM762-RC2 represents an outlier in the market due to the back pressure performance.

In this review, the SOCOM762-RC2 performance metrics depend upon suppressing a supersonic centerfire rifle cartridge; no easy task. How would the SOCOM762-RC2 perform, with a WARCOMP or Flash Hider mount, on your .308 deer rifle?
