AR-15 BLACK NITRIDE 5.56 HPT/MPI BOLT CARRIER GROUP

Of all the parts in an AR nothing takes more punishment than the bolt carrier group. With chamber pressures of up to 62,000 psi, compromise should never be a consideration when selecting a BCG. This is why 80percentlowers.com has taken the Mil-Spec standard and shelved it for better metals, better standards and no compromise. Enter the 80percentlowers.com AR-15 Black Nitride 7.62 X 39 Bolt Carrier Group!
