KAK Industry K-SPEC AR-15 5.56 Bolt Carrier Group – Cerakote Desert – AR-15/M16

The KAK Industry K-SPEC Bolt Carrier Group is a mil-spec replacement BCG for AR-15 platform rifles chambered in 5.56 NATO/.223 Remington. Built to M16 full-auto profile specifications, this BCG provides reliable cycling and consistent lockup for both semi-auto and full-auto/select-fire firearms. The Desert finish offers corrosion resistance and a distinct appearance for builders seeking a non-traditional color option.

Machined from 8620 steel with a properly staked gas key, this BCG features a carpenter 158 steel bolt with shot-peened surfaces and magnetic particle inspection (MPI) testing. The Cerakote Desert finish is applied to the carrier body, while the bolt remains silver for reduced friction at critical contact points. Installation is drop-in for standard AR-15 upper receivers with no fitting required.
