The advanced SureFire SFMB muzzle brake greatly reduces both recoil impulse and muzzle rise so that the weapon tracks straight back to keep you on target for faster shot-to-shot recovery. Its patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects. The SFMB also serves as a rock-solid mounting adapter for SureFire SOCOM Series Fast-Attach® suppressors.
