Overview
The CMMG AR-15 Magazine Catch is designed with an ambidextrous configuration, allowing for seamless operation from either side of the rifle. This feature is particularly beneficial for builders who prioritize versatility in their setups, accommodating both left- and right-handed shooters with ease. You’ll often find this magazine catch in builds utilizing a mid-length gas system chambered in 5.56 NATO, where user accessibility and efficiency are key.

CMMG ambi mag catch matches their other parts well in finish quality. Drop-in fitment in any milspec lower. Both sides press cleanly. Black anodize is matte and consistent. Cheaper than the higher end ambi catches without sacrificing function.
CMMGs ambi mag catch has the right paddle for right side activation. Both sides press cleanly. The black anodize has some flat-vs-satin variation across the parts in the package, only visible in side by side comparison. Mechanically perfect, drops in any milspec lower.
