The CMMG 9mm AR-15 Conversion Mag Adapter fits into a Gen2 or Gen3 Magpul PMAG to allow you to shoot 9mm ammo through an unmodified AR-15 lower when paired with a CMMG 9mm Radial Delayed Blowback Upper. The Adapter fits neatly into a PMAG, and holds 30 rounds of 9mm ammo while maintaining last-round hold-open.

PLEASE NOTE: Requires both a Gen2/Gen3 Magpul PMAG and a CMMG 9mm Radial Delayed Blowback Upper to function.
