SureFire SOCOM556-RC4 5.56mm Suppressor Overview The SureFire SOCOM556-RC4 is a compact, next-generation 5.56mm suppressor built for extreme durability, reduced back pressure, and superior flash suppression. Constructed entirely from U.S. mill-certified Inconel, it withstands the intense heat and erosion of sustained fire-even on short-barreled rifles. Its advanced gas flow design and reinforced muzzle deliver unmatched signature reduction and longevity. The SOCOM556-RC4 mounts quickly and securely with the proven Fast-AttachA(R) system and is backward compatible with existing SOCOM muzzle devices. Key Features a Advanced gas-flow dynamics significantly reduce flash signaturea Reinforced front plate increases durability under extreme usea Low-back-pressure design reduces gas-to-face by ~60%a Improved recoil control and cleaner firearm operationa Optimized for 10.3" and longer barrelsa Compact 6.3" overall length adds only 3.8" to weapona 100% Inconel construction for maximum heat and erosion resistancea Tool-less Fast-AttachA(R) system for rapid mounting and removala Backward compatible with all SOCOM Fast-AttachA(R) muzzle devicesa Optimized for SF3P, FH556RC, and WARCOMP open-tine flash hidersa Designed, engineered, and manufactured in the U.S.A.
