KAK Industry AR15 BCG M16 224/6.8 CLP BLK – AR-15 Bolt Carrier Group

The KAK Industry AR15 BCG is a full-auto profile M16 bolt carrier group designed for AR-15 platforms chambered in .223/5.56 and 6.8 SPC. This BCG provides reliable cycling and extraction across a range of ammunition types and barrel lengths. The full-auto carrier adds mass for consistent function in both semi-automatic and select-fire applications, though most shooters will appreciate the added reliability in standard semi-auto rifles.

Machined from 8620 steel with a Carpenter 158 steel bolt, this BCG features a black Corrosion-Resistant Phosphate (CLP) finish that provides durable protection against wear and the elements. The gas key is properly staked per mil-spec standards. Installation is drop-in for any mil-spec AR-15 upper receiver—no fitting or gunsmithing required. A solid choice for builders seeking a dependable carrier group without unnecessary frills.
