CMMG ARC Gen II 9mm 33-Round Polymer Magazine for AR-15

This black polymer magazine is a 9mm adapter magazine for AR-15 platform rifles. It holds up to 33 rounds of 9mm Luger ammunition and seats in a standard AR-15 magwell, allowing 9mm shooting from an AR-15 lower receiver when paired with a compatible upper.

The CMMG ARC Gen II works by inserting a 9 ARC conversion insert into a Magpul PMAG Gen 2 or Gen 3 magazine body. The magazine feeds the CMMG 9mm Radial Delayed Blowback Upper and supports last round bolt hold-open. It uses a standard carbine buffer and action spring.

Compatibility is limited to the CMMG 9mm Radial Delayed Blowback Upper, AR-15 lowers, and Magpul PMAG Gen 2 or Gen 3 bases.
