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. The 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 SureFires combat-proven SOCOM Series Fast-Attach suppressors. The SFMB design incorporates multiple bearing surfaces to ensure superior suppressor alignment. Blind pilot holes on 5.56 and 7.62 models enable fine-tuning of recoil characteristics for individual shooting styles.
