AR308/AR10 Bolt Carrier Groups

We carry nickel boron and black nitride-finished AR308 and AR-10 BCGs to add to your large-frame AR build. The extra finish helps reduce friction during firing, protect against corrosion and wear, and improve the overall performance of your rifle. All our large frame bolt carrier groups feature a DPMS pattern or come DPMS-compatible for other setups that follow the DPMS style of barrel and bolt, including 6.5 Creedmoor and SR-25.
