The advanced SureFire ProComp 556 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 ProComp 556 muzzle brake has a black Melonite finish that provides maximum protection under harsh environmental conditions. This muzzle brake fit M4/M16 weapons and variants with 1/2-28 muzzle threads. The SureFire ProComp 556 muzzle brake has a blind pilot hole at the 3 and 9 o'clock position to enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. Each ProComp 556 muzzle brake is covered by SureFire's No-Hassle Promise.
