CMMG ZEROED Extended Ambi Magazine Catch

The CMMG ZEROED Extended Ambi Magazine Catch pairs ambidextrous operation with an extended release bar, so the shooter gets a support-side release plus more leverage than a flush mil-spec button. On a standard lower the mag-release button sits on the right side; this adds a left-side release a support hand or a left-handed shooter can reach without breaking grip.

It installs in place of the standard magazine catch with no receiver modification, and CMMG lists it as working with mil-spec style and aftermarket mag release buttons.

In an ambi conversion this is the step up from a basic ambi catch: the extended bar makes it the pick for a duty or training rifle where reload speed and leverage matter more than keeping the lowest possible profile. The extended bar does sit slightly proud, so builders prioritizing a snag-free setup should weigh that against the leverage gain.
