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.
