KAK Industry AR-15 M16 Bolt Carrier Group – 5.56 NATO K-SPEC Chrome Desert Earth

The KAK Industry K-SPEC Bolt Carrier Group is an M16-profile carrier designed for reliable cycling in AR-15 rifles chambered in 5.56 NATO/.223 Remington. The M16 profile features a full-auto cut on the carrier, increasing bolt mass for improved reliability in suppressed or overgassed builds and ensuring compatibility with adjustable gas systems. This BCG provides consistent function whether you're running a carbine-length gas system or a pistol-length setup.

The carrier features a durable chrome finish with a Desert Earth Cerakote exterior, combining corrosion resistance with a low-signature finish. The chrome-lined interior ensures smooth operation and easy cleaning. The bolt is machined from Carpenter 158 steel and properly staked per mil-spec standards. Installation is drop-in for any mil-spec AR-15 upper receiver—no gunsmithing required.
