CMC AR-10 Bolt Carrier Group .308 Nitride Black

Black nitride is the first thing that stands out here, and for a working AR-10 bolt carrier group that matters. It gives this CMC unit a slick, corrosion-resistant surface, while the rest of the build stays focused on hard use with a hardened 4340 cam pin, a mil-spec 8740 steel firing pin, and MPI and HPT testing.

CMC also set it up with enlarged forward ports and notes it is optimized for suppressor use. Compatibility covers both .308 and 6.5 Creedmoor, and the extractor setup uses a mil-spec spring and O-ring.
