This OEM Overrun AR10 BCG has different technical specifications than Faxon's general AR10 BCG. Please read the technical specifications below.
AR10 Bolt Carrier Group for AR10, no forward assist, semi-auto. Not Superfinished.
Improvements include using 9310 tool steel for the bolt, nitriding the assembly to increase surface hardness, decrease resistance, and have superior corrosion resistance compared to typical chrome and phosphasted bolt carrier groups. All bolts are fully MPI tested to ensure the material is sound and without defects. Bolt lugs are chamfered 45 degrees to ensure reliable action for even the highest pressure hand loads and fast lightweight actions. Gas keys use grade 8 fasteners and are fully staked for a lifetime of service.

This was one of the last pieces I needed for my AR-10 build and, as usual, Faxon didn't disappoint. Fit and finish were excellent and after a quick clean and lube it performed as well as could be hoped.
Looks great and functions perfectly. Saved me a lot of money and still has Faxon quality.
Very well manufactured, a great addition to my build. Price couldn't be ignored. Another great product purchase from Faxon. Fast delivery.
Beautiful part, as always but staking on the gas key was visibly insufficient. Would still buy again
