KAK Industry KSPEC AR-15 Bolt Carrier Group 5.56 NATO – Dark Earth Carrier, Black Bolt

The KAK Industry KSPEC Bolt Carrier Group is a complete, mil-spec AR-15 BCG designed for 5.56 NATO and .223 Remington chambered rifles. This BCG delivers reliable cycling and extraction with a two-tone finish that combines a dark earth carrier with a black bolt for visual distinction during maintenance and inspection. It's built to meet or exceed military specifications for shooters who demand consistent performance without unnecessary frills.

The carrier is coated in a durable dark earth finish, while the bolt features a black nitride or phosphate coating for corrosion resistance and ease of cleaning. The KSPEC BCG is machined from 8620 steel (carrier) and 9310 steel (bolt), both standard materials for mil-spec carriers. Gas key is properly staked. This is a drop-in replacement for standard AR-15 platforms—no fitting or gunsmithing required.
