CMMG
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 AR-15 Magazine Catch Ambidextrous ranked #19 of the 91 magazine releases builders added on GunPartPicker in August 2026. Builders have been adding it to their builds on GunPartPicker since February 2026. All time, it ranks #19 of the 165 magazine releases builders have added. Builds with this magazine release are split between 5.56 NATO (57%) and .223 Wylde (13%), mostly on mid-length gas (63%, then rifle-length 22%), and mostly AR-15 (78%, then AR-10 23%).
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today 4 of the 6 retailers we track have it in stock. It dipped to $26.92 at Brownells for a stretch in August 2026, under its usual $29.16 to $32.99, so sales do come around.

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.
