Surefire Procomp Muzzle Brake 7.62mm

The advanced SureFire ProComp 762 muzzle brake, which fits AR10/LR308 weapons and variants with 5/8-24 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 762 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 762 muzzle brake has a black Melonite finish that provides maximum protection under harsh environmental conditions. 
The SureFire ProComp 762 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 762 muzzle brake is covered by SureFire’s No-Hassle Promise. 
FITS: AR10/LR308 and variants with 5/8-24 muzzle threads 
NOTE: SureFire ProComp muzzle brakes are stand-alone muzzle devices and do not serve as mounts/adapters for any SureFire Fast-Attach® sound suppressors.
