Advancing at the Speed of Sound. The SureFire SOCOM556-RC4 stands as the premier 5.56mm combat suppressor, combining extreme durability, reduced back pressure, and unmatched flash reduction—all in a compact SOCOM Fast-Attach® platform.
Crafted entirely from U.S. mill-certified Inconel superalloy, the SOCOM556-RC4 resists the punishing heat and erosion of sustained 5.56 fire, even from short-barreled rifles. Its fusion of precision-machined and 3D-printed aerospace-grade components, joined by advanced CNC laser welding, delivers the legendary structural endurance that defines SureFire suppressors worldwide. The redesigned muzzle enhances flow, slashes flash, and provides superior signature reduction—giving operators a decisive edge in stealth-critical missions. From the first shot to the last, even under extreme heat, SureFire’s flash suppression remains industry-leading. Reinforced at the front end, the RC4 is built to withstand impacts and keep performing long after others fail.
SureFire’s breakthrough low-back-pressure architecture cuts back pressure by up to 60% compared to traditional suppressors. The result: less gas in the shooter’s face, cleaner firearm operation, reduced wear on components, and improved recoil control. The SOCOM556-RC4 attaches via the proven Fast-Attach system, enabling rapid, tool-free mounting and removal while remaining backward compatible with millions of SOCOM Fast-Attach flash hiders already in service.
Proudly engineered in the U.S.A., the SOCOM556-RC4 is without equal—built for the modern battlefield and trusted to deliver the durability and performance professionals demand.
