Description
The standard AR-15 magazine catch is designed around a right-handed grip, requiring left-handed shooters to break their firing hold to drop a magazine. CMMG’s ambidextrous magazine catch solves that without adding levers, paddles, or external hardware that can snag gear or complicate the profile of the lower receiver. The right-side release paddle integrates cleanly into the receiver, keeping the overall silhouette close to what a standard catch produces.
Installation is a drop-in process that replaces the existing catch, button, and spring as a complete unit — CMMG includes all three components in the kit. The catch is compatible with AR-15 and M16 platform lowers built to mil-spec dimensions, and the design does not rely on the face thickness of the lower receiver as a pivot point, which gives it broader compatibility across both mil-spec and certain billet lower receivers where catches that do depend on that reference surface may not seat correctly.
The finish is black, and the button profile blends with the standard appearance of the lower rather than drawing attention to itself. For a shooter running a left-handed or cross-dominant setup, or anyone who wants the option to actuate the release from either side without adjusting grip, this is a straightforward and unobtrusive solution from the company that manufactures the receivers it is designed to complement.
