KAK Industry K-SPEC Bolt Carrier Group 7.62x39 NP3

The KAK Industries K-SPEC Bolt Carrier Group is a steel AR-15 pattern bolt carrier group chambered for 7.62x39mm. It is intended for builders assembling a 7.62x39mm upper or owners replacing a worn carrier in a compatible AR-pattern rifle.

The carrier is finished in NP3, a nickel-Teflon coating that reduces friction between the bolt and carrier and helps resist carbon fouling buildup, which can make cleaning easier. The group weighs 11.5 ounces, in line with standard AR bolt carrier groups, and is sized for the pressures and dimensions of the 7.62x39mm cartridge.
