CMMG ambi catch upgrade
Reviewed on May 13, 2026Verified with Build

CMMG ambi mag catch is a great upgrade over a single side mag catch. Right side paddle is sized for trigger finger activation. Both sides press cleanly. Black anodize matches CMMG receivers. Drop in fitment with the standard catch spring.

CMMG ambi catch no detent
Reviewed on April 22, 2026Verified with Build

CMMG ambi mag catch works correctly with the standard catch spring. Wish the package included a backup detent for the price - those small parts go flying during install. Function is reliable once together. Anodize matches CMMG lowers.

CMMG ambi mag catch
Reviewed on April 10, 2026Verified with Build

CMMGs ambi mag catch lets me drop a mag from the right side with my trigger finger which is way faster during reloads. The right side paddle is sized correctly to avoid accidental presses. Drop-in fitment with the standard spring. Anodize matches my CMMG receiver.
