A smooth black nitride finish and design exceeding military specifications increases durability, strength and service life while reducing clean up time and the amount of dust and grime grabbing oil needed to keep your rifle running at peak performance time after time for years to come. This second generation features a more robust design which better balances the overall weight and durability while greatly reducing surface to surface friction allowing your weapon to run smoother and cooler. This complete bolt carrier group is a perfect upgrade for any AR .308 (LR-308) platform rifle and is completely legal in all 50 states.
