Description
The SureFire ProComp 556 is a standalone muzzle brake engineered for rifles with 1/2-28 muzzle threads, including M4/M16 and AR-15 variants. Its Impulse Diffusion porting is designed to reduce recoil impulse and muzzle rise so the rifle tracks straight back for faster follow-up shots. Precision machined from U.S. mill-certified steel and finished in black nitride/Melonite, the ProComp is built for durability in demanding environments. Note that this model is not intended to serve as a mount or adapter for SureFire SOCOM/fast-attach suppressors.
