AR-15 Magazine Catch
The United Defense AR-15 Magazine Catch is a complete mil-spec magazine catch assembly designed to drop directly into any standard AR-15, M4, or M16-pattern lower receiver. Built from hardened steel with a matte phosphate finish, the assembly includes the catch body, knurled release button, and spring for a full installation. Precision-cut to mil-spec tolerances, it delivers positive magazine lockup and clean releases with USGI and aftermarket mags alike.
