Reign Over Recoil. SureFire SFMB muzzle brake suppressor adapters greatly reduce both recoil impulse and muzzle rise so that your weapon tracks straight back, keeping you on target for faster shot-to-shot recovery. Our proprietary Impulse Diffusion design minimizes side blast and rear-directed concussion effects. Precision machined from U.S. mill-certified heat-treated stainless steel bar stock and DLC-coated for extreme durability, they are available for a variety of weapon calibers and muzzle thread specs, and every SFMB serves as a rock-solid mounting adapter for SureFire’s combat-proven SOCOM Series Fast-Attach® suppressors. The SFMB design incorporates multiple bearing surfaces to ensure superior suppressor alignment. Blind pilot holes at the 3 o’ clock and 9 o’clock positions enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. Blind pilot holes at the 6 o’clock position enable indexing the adapter at bottom dead center. All that’s required is a basic hand drill and appropriate drill bits.
