KAK Industries Bolt Carrier Group 5.56 / .300 AAC Blackout Titanium Gray

The KAK Industries Bolt Carrier Group is a replacement BCG for the AR-15 platform, built on a full M16 auto profile carrier paired with a 9310 steel bolt. The NP3 finish, an electroless nickel plating combined with a fluoropolymer, is intended to reduce friction across the carrier and bolt surfaces and to resist carbon adhesion during extended firing sessions. An NP3-coated cam pin and a 4130 steel gas key complete the assembly.

This group is compatible with both 5.56 NATO and .300 AAC Blackout chamberings on the AR-15, so shooters can change caliber conversions without swapping the BCG. The Titanium Gray finish differs from typical black nitride or phosphate finishes. It is a right-hand, standard-type group.
