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