When purchasing Surefire or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

The advanced SureFire PROCOMP-762-5/8-24 muzzle brake, which fits AR10/LR308 rifles and variants with 5/8-24 muzzle threads, greatly reduces both recoil impulse and feature neutral porting so brake loads bi-pod legs evenly 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-762-5/8-24 duplicates the design of the SureFire SOCOM SFMB-762/.308 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-762-5/8-24 muzzle brake has a black Melonite finish that provides maximum protection under harsh environmental conditions. The SureFire PROCOMP-762-5/8-24 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. It also has blind pilot holes at the 6 o'clock position to enable indexing the adapter at bottom dead center, and to pin-and-weld on short-barreled rifles. All that is required is a basic hand drill and appropriate drill bits.
