The ProComp 556 fits M4/M16 weapons and variants with 1/2-28 muzzle threads, while the SureFire ProComp 762 fits AR10/LR308 rifles and variants with 5/8-24 muzzle threads. Whichever you choose, you can count on a muzzle brake that greatly reduces both recoil impulse and muzzle rise so that your weapon tracks straight back to keep you on target for faster shot-to-shot recovery. Our proprietary Impulse Diffusion design minimizes side blast and rear-directed concussion effects or even greater accuracy. Every ProComp features blind pilot holes at the 9 o'clock position to enable fine-tuning of recoil traits for individual shooting styles or ammunition characteristics. All that is required is a basic hand drill and appropriate drill bits. **FEATURES** - Offset porting greatly reduces recoil impulse and muzzle rise so the weapon tracks straight back to keep you on target for faster shot-to-shot recovery - Precision machined from U.S. mill-certified steel bar stock - High-precision barrel threads for optimum thread interface - Pilot hole located at 9 o'clock for tuning to suit individual shooting styles or ammunition characteristics - Pilot hole located at 6 o'clock for pin-and-weld applications - Black nitride coating provides maximum protection against harsh environmental conditions - Advanced muzzle brakes for your 5.56 mm or 7.62 mm long gun - Significant muzzle rise and recoil impulse reduction - Patented Impulse Diffusion design minimizes side and rear blast **SPECIFICATIONS** - FINISH: Nitride Finish - CALIBER: 5.56 mm, 7.62 mm - WEIGHT: 5.56 mm - 3.4 oz (96 g), 7.62 mm - 3.1 oz (90 g) - LENGTH: 5.56 mm - 2.5 in (6.35 cm), 7.62 mm - 2.7 in (6.85 cm) ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
