The Luth-AR Full Bolt Carrier Group Assembly in .223 with a titanium nitride (TiN) coated bolt (brand part no. BCA223T) gives builders a complete, ready-to-install BCG for a standard .223 Rem/5.56 NATO AR-15 upper. Luth-AR assembles this BCG as a full unit rather than a stripped carrier, including the bolt, cam pin, firing pin, and retaining pin, so it drops into a mil-spec upper and functions out of the box. The TiN coating on the bolt adds a smoother, more corrosion- and wear-resistant surface than a bare or phosphate-finished bolt, helping extend service life and ease cleaning between range sessions.

Frequently Asked Questions

Will this fit a large-frame .308 upper? No, this BCG is sized for standard .223/5.56 AR-15 uppers, not large-frame .308/7.62-pattern uppers.

Does the TiN coating require special cleaning? No, it cleans like a standard BCG, though its smoother surface typically makes carbon and fouling easier to wipe away.
