SureFire ProComp muzzle brake, fits M4/M16 weapons and variants with 1/2-28 muzzle threads. It 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. The patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects. 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. NOTE: This model cannot be used to mount SureFire SOCOM suppressors.
