The SureFire SFMB Muzzle Brake (brand part no. SFMB-762-5/8-24) is a 7.62mm muzzle device built with SureFire’s proprietary Impulse Diffusion design to greatly reduce both recoil impulse and muzzle rise, keeping the rifle tracking straight back for faster shot-to-shot recovery. SureFire precision-machines this brake from U.S. mill-certified heat-treated stainless steel bar stock, threads it 5/8×24 tpi, and DLC-coats it for durability, and every SFMB doubles as a mounting adapter for SureFire’s SOCOM Series Fast-Attach suppressors. Blind pilot holes at the 3, 6, and 9 o’clock positions let a gunsmith fine-tune recoil characteristics or index the adapter with a basic hand drill.
