RADIAN Enhanced BCG for AR-15 – Black Nitride

The RADIAN Enhanced Bolt Carrier Group delivers precision machining and proven reliability for AR-15 pattern rifles. This bolt carrier group replaces factory BCGs to provide smoother cycling, reduced fouling buildup, and improved longevity through thousands of rounds. Shooters choose this BCG for its consistent performance in competition, duty, and training environments where reliability matters.

Machined from 8620 steel with a black nitride finish, this carrier resists corrosion and wear while reducing friction for smoother operation. The black nitride treatment penetrates the metal surface rather than coating it, providing long-lasting protection that won't flake or peel. This is a drop-in component for standard AR-15 rifles—no gunsmithing required. Remove your existing BCG, install this unit, and function check per standard procedures.
