Battle Arms Development Enhanced Magazine Release Kit, AR-15/AR-10, Black Phosphate

The Battle Arms Development Enhanced Magazine Release Kit (Battle Arms part no. BADMRKPK1) is a complete drop-in upgrade for the AR-15 and AR-10 platforms, finished in black phosphate to match most mil-spec lower receivers. The kit bundles the three parts needed for the swap: an extended catch/index cap, a magazine catch spring, and an oversized release button, so there’s no need to source parts separately. Battle Arms builds the release button larger than the mil-spec original, giving a shooter faster, more positive mag changes without breaking their firing grip. It’s a straightforward reliability and speed upgrade for a competition, duty, or home-defense AR build.
