“F-Style” Bolt Carrier Group
Dual Muzzle Attachment System & Nitride Heat Treated Fluted Chamber Barrel
Each barrel is precision machined and threaded. The combination 3-lug and 1/2 X 28 TPI attachment systems ensure consistent engagement and lock up of an expansive range of suppressors and other muzzle attachments.
NITRIDE HEAT TREATED FLUTED CHAMBER BARREL
Cold Hammer Forged (CHF) chrome molybdenum (CM) chamber fluted barrel finished through the nitride heat-treating process. Each barrel is hand pressed into the trunnion to ensure proper head spacing and provide guaranteed free float accuracy and dependability.
The receiver encompasses the heart of the roller lock system and therefore receives our greatest level of attention to detail during construction. Anything less would require us to compromise in the areas of fitment and function. And because that’s not an option, we take extreme care to ensure only the best receiver makes it past our quality control process.
4140 ordnance grade steel that is machined to within .0005 tolerance to maintain our exacting standards. This consistency allows us to hand press each and every barrel to the correct headspace and ensure both longevity and the accuracy achieved from the free float effect.
