The SureFire SOCOM Muzzle Brake in 7.62mm with 5/8-24 threads (SureFire part no. SFMB-762-5/8-24) is the SFMB, a recoil-reducing brake that doubles as the mounting adapter for SOCOM Series Fast-Attach suppressors. SureFire uses a proprietary Impulse Diffusion design with offset porting to cut recoil impulse and muzzle rise, so the rifle tracks straight back for faster shot-to-shot recovery, and to minimize side blast and rear-directed concussion. It is machined from heat-treated stainless steel and DLC coated. This is the 7.62mm version for 5/8-24 muzzle threads, aimed at .308 builds that want one muzzle device for both brake and suppressor days.

Key Specifications
