SureFire SOCOM556-MINI4 5.56mm Compact Suppressor, Black Overview The SureFire SOCOM556-MINI4 is an ultra-compact 5.56mm suppressor engineered for extreme durability, reduced back pressure, and industry-leading 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 next-generation flow-optimized design significantly decreases gas blowback while maintaining superior signature reduction. The MINI4 mounts using SureFire's proven Fast-AttachA(R) system and is backward compatible with existing SOCOM muzzle devices. Key Features a Ultra-compact 5.5" suppressor optimized for 10.3"+ barrelsa 100% Inconel construction for maximum heat and erosion resistancea Advanced flow design cuts back pressure by approximately 60%a Industry-leading flash suppression with revised front plate for added durabilitya Enhanced recoil control and reduced gas-to-face for improved shooter comforta Compatible with SureFire SOCOM Fast-AttachA(R) muzzle devicesa Optimized for SF3P, FH556RC (4-prong), and WARCOMP open-tine flash hidersa Tool-less Fast-AttachA(R) system enables rapid attachment and removala Machined and 3D-printed aerospace-grade components with CNC laser weldinga Designed, engineered, and manufactured in the U.S.A.
