CMMG ZEROED AR15 AMBI MAG CATCH

Description

Standard AR-15 magazine releases are designed for right-handed operation, which means left-handed shooters have to break grip or contort their trigger hand to drop a mag. The CMMG ZEROED Ambi Mag Catch and Button Kit solves that without requiring any modification to the lower receiver itself. The ambidextrous catch adds a release bar on the right side of the lower, letting a left-handed shooter push the button with their trigger finger the same way a right-hander would from the left side — same motion, same speed, no compromise.

What separates this from a basic ambi mag catch is the extended-release bar. The additional length gives the shooter more surface area to press against and requires less precise finger placement to actuate, which matters when running drills at speed or wearing gloves. The serrated texture on the extension keeps your finger from sliding off under pressure rather than relying on friction alone.

Installation doesn’t require a gunsmith. The adapter button threads into the existing mag catch, and the button extension attaches to the adapter — two steps, no special tooling. The kit is built from steel throughout, so it holds up to the same mechanical stress as the factory component it augments. CMMG backs it with their Lifetime Quality Guarantee. One compatibility note worth knowing from verified user experience: the extended bar does extend past where a standard mag catch sits, which can interfere with certain aftermarket bolt-assist devices that occupy that same space on the right side of the lower — worth checking against your current build before ordering.
