The SureFire ProComp 556 muzzle brake is engineered to fit M4/M16 weapons and variants with 1/2-28 muzzle threads. Its patented Impulse Diffusion design significantly reduces recoil impulse and muzzle rise while minimizing side blast and rear-directed concussion effects, keeping your weapon tracking straight back for faster shot-to-shot recovery.
Built from US mill-certified steel bar stock with high-precision cut threads for optimum thread interface, the ProComp 556 features a black Melonite finish designed to withstand harsh environmental conditions. A blind pilot hole at the 9 o’clock position allows fine-tuning of recoil characteristics to match individual shooting styles or ammunition characteristics.
Note that the ProComp 556 duplicates the design of the SureFire SOCOM SFMB-556-1/2-28 muzzle brake but cannot be used to mount SureFire SOCOM suppressors. Each ProComp 556 muzzle brake is covered by SureFire’s No-Hassle Promise.
