Faxon AR10 308 OEM Overrun Bolt Carrier Group

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.

    Great Combo

    I built this on a Aero Precision M5 base. Light weight and god balance with a MFT Minimalist stock. Shoots great with Hornady Match 108gr ELD-M. Bolt having no assist cut isn't a factor for me. Glade I bought two.
