Description
This Armaspec bolt carrier group is a mil-spec-dimensioned, direct drop-in replacement for AR-15 rifles chambered in .223 Remington, 5.56 NATO, or .300 Blackout. The carrier and 9310 steel bolt receive a salt-bath nitride treatment, which hardens the surface, reduces friction for smoother cycling, and simplifies cleaning compared to untreated chrome-moly BCGs. The bolt is magnetic-particle inspected and the gas key is staked.
