The SureFire SOCOM556-RC4 sets the benchmark for modern 5.56mm suppressors, delivering unmatched durability, reduced signature, and superior shooting performance in a combat-proven package. Engineered for professional end-users and serious shooters alike, the RC4 represents the next evolution in suppressor technology.

Constructed entirely from U.S. mill-certified Inconel superalloy, the SOCOM556-RC4 is built to withstand extreme heat, pressure, and sustained fire—even on short-barreled rifles. Its advanced design incorporates precision machining, 3D-printed aerospace-grade components, and CNC laser welding to ensure exceptional structural integrity and long-term reliability.

The RC4 features fourth-generation flow dynamics, reducing back pressure by up to 60% compared to traditional suppressors. This results in less gas blowback, improved weapon reliability, reduced fouling, and enhanced recoil control—allowing for smoother, more controlled shooting in any environment.

A redesigned muzzle significantly improves flash suppression, minimizing visible signature from the first round to the last—even under high heat conditions. Combined with SureFire’s Fast-Attach® mounting system, the RC4 provides rapid, secure attachment and removal without tools, while remaining backward compatible with a wide range of SOCOM muzzle devices already in the field.

Compact, rugged, and purpose-built, the SOCOM556-RC4 is optimized for 10.3" barrels and longer, adding minimal length and weight while delivering maximum performance.
