The advanced SureFire ProComp 556 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 ProComp 556 duplicates the design of the SureFire SOCOM SFMB-556-1/2-28 muzzle brake, but unlike the latter it cannot be used to mount SureFire SOCOM suppressors.
Precision machined from US mill-certified steel bar stock—including high-precision cut threads for optimum thread interface—the ProComp 556 muzzle brake has a black Melonite finish that provides maximum protection under harsh environmental conditions.
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.
FITS: M4, M16 and variants with 1/2-28 muzzle threads
