The SureFire SOCOM300-SPS Dark Earth suppressor brings SureFire’s subsonic-focused .300 Blackout can to tan and FDE rifles (SureFire part no. SOCOM300SPSDE). SureFire calls it the quietest suppressor it has ever designed, and its highly specialized V-shaped baffles are tuned first for subsonic ammunition while virtually eliminating first-round flash and dust signature. An oversized but precision-machined bore lowers the chance of a baffle strike from an unstable projectile. Tight tolerances and precise bore concentricity support accuracy, and internal venting reduces back pressure, cyclic rate and gas blowback. Built for .300 BLK/Whisper (7.62×35) carbines with barrels of 10 inches or shorter, it is the choice for a quiet short-barrel build in an earth-tone finish.

Key Specifications

• The body color is Dark Earth, over an Ionbond and Cerakote finish that resists wear and heat.

• Overall length is 7.9 inches, sized by SureFire for stronger signature reduction.
• Length added to the weapon is 5.4 inches, which shifts with the SureFire adapter you mount it on.

• The V-shaped baffle stack is designed to promote sound suppression with subsonic ammunition.
