The advanced SureFire SFMB-556-1/2-28 muzzle brake, which fits M4 / M16 weapons and variants with 1/2-28 muzzle threads, 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-556-1/2-28 also serves as a rock-solid mounting adapter for SureFire SOCOM Series 5.56 suppressors.
