Bolts & Bolt Carrier Groups

Browse our selection of bolt carrier groups, bolts and carriers. The BCG is the heart of an AR: it strips, chambers, locks and extracts every round, so a properly staked gas key and a magnetic-particle-tested bolt matter. We carry full-weight and lightweight carriers in nitride, phosphate and nickel boron for AR-15 and AR-10 rifles, plus bolts for rimfire and bolt-action guns.
