SUREFIRE SOCOM556-RC4 5.56 - BLACK

The SureFire SOCOM556-RC4 is the latest evolution of the legendary SOCOM suppressor series, engineered to deliver exceptional durability, dramatically reduced back pressure, and industry-leading flash suppression for professional shooters, military personnel, law enforcement, and serious enthusiasts. Built entirely from U.S. mill-certified high-temperature Inconel superalloy, the RC4 is designed to withstand the extreme heat, pressure, and abuse generated by sustained firing on 5.56 NATO platforms, including short-barreled rifles.

Featuring fourth-generation gas flow dynamics, the SOCOM556-RC4 reduces back pressure by approximately 60% compared to conventional suppressors. The result is significantly less gas blowback to the shooter, improved firearm reliability, reduced fouling, smoother recoil impulse, and a cleaner-running rifle during extended shooting sessions.

The redesigned front end enhances both durability and flash suppression, providing exceptional signature reduction from the very first round through prolonged firing. Whether operating in daylight or low-light environments, the RC4 minimizes visible flash while maintaining consistent performance under demanding conditions.

SureFire's proven Fast-Attach® mounting system allows quick, secure, tool-free installation and removal while maintaining exceptional repeatability. The SOCOM556-RC4 is fully compatible with existing SureFire SOCOM Fast-Attach muzzle devices, making it an easy upgrade for current SureFire suppressor users.

Optimized for barrels 10.3 inches and longer, the SOCOM556-RC4 adds only 3.8 inches to the firearm while delivering the combat-proven performance and reliability that have made SureFire suppressors trusted worldwide.
