AR-15 Bolt Carrier Groups

Ensure your rifle cycles smoothly and reliably with high-performance AR-15 bolt carrier groups (BCGs). This collection includes full-auto rated, mil-spec, and enhanced BCGs designed for hard use and high round counts. Choose from black nitride, phosphate, and nickel boron finishes to match your performance and maintenance preferences. Whether you’re building from scratch or upgrading your current setup, a quality BCG is the heart of your rifle’s reliability. All models are tested for proper staking, magnetic particle inspection (MPI), and shot peening—built to meet or exceed industry standards for AR-15 platforms in 5.56 NATO, .223 Wylde, and other calibers.
