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-Attach® system and is backward compatible with existing SOCOM muzzle devices.

Key Features
