An M16 Bolt-Carrier Group That Completes Your Rifle Build
Whether you're looking to finalize your latest AR build or have a spare on-hand to keep your current AR-15 running, having an M16 bolt-carrier group is a must, and this high-quality bolt-carrier group is one of the best options on the market. The carrier is machined from 8620 steel, and the bolt is machined from Carpenter 158 tool steel.
Before leaving the factory, each bolt-carrier group is shot-peened and magnetic-particle inspected for quality. The gas key is properly torqued and staked, and the black-nitride finish provides a low-friction surface that aids in operation. The total weight of this M16 bolt-carrier group is 11.52 ounces.
