This bolt carrier group from Advanced Armament Corporation would make a great choice for a new AR-15 build or upgrade for an existing modern sporting rifle. The full auto profile carrier is nickel-boron coated for smooth, reliable action. The Mil-Spec bolt is made from Carpenter 158 steel. The carrier has a proprietary cam pin travel path, and the carrier key is properly staked with Permatex.
