Frequently Asked Questions

Will this ambi mag catch fit my AR-15 lower receiver?

Yes. The CMMG Ambidextrous Magazine Catch is designed to be compatible with all mil-spec AR-15 and M16 lower receivers. It installs in the same location and uses the same method as a standard factory magazine catch, so no drilling, milling, or gunsmithing is required. If your lower accepts a standard mag catch, this unit will fit.

Does this require any special tools or modifications to install?

No special tools or permanent modifications are needed. The CMMG ambi mag catch is a true drop-in replacement that follows the same installation process as the OEM factory part. A basic AR-15 armorer's block and a standard punch set are all you need to complete the swap in just a few minutes.

How does the ambidextrous release work for left-handed shooters?

Unlike a standard AR-15 mag catch — which is only operable from the right side of the rifle — this CMMG ambidextrous design adds a left-side paddle that allows a left-handed shooter to drop the magazine with their trigger-hand thumb, just as a right-handed shooter would. This enables faster, more natural magazine changes without awkward hand repositioning or breaking your firing grip.
