SureFire SFMB muzzle brake suppressor adapters significantly reduce recoil impulse and muzzle rise, ensuring your weapon tracks straight back for faster shot-to-shot recovery. SureFire’s proprietary Impulse Diffusion design minimizes side blast and rear-directed concussion effects. Machined from U.S. mill-certified heat-treated stainless steel bar stock with DLC coating for extreme durability, these adapters are available for various weapon calibers and muzzle thread specifications. Each SFMB also functions as a reliable mounting adapter for SureFire’s combat-proven SOCOM Series Fast-Attach suppressors. The SFMB design features multiple bearing surfaces to ensure precise suppressor alignment. Blind pilot holes on 5.56 and 7.62 models allow fine-tuning recoil characteristics for different shooting styles. All that’s needed is a basic hand drill and the appropriate drill bits.
