CMMG's 9 AR Conversion Magazines make it possible to shoot 9mm ammunition from your unmodified AR15 lower receiver when paired with a CMMG 9mm Radial Delayed Blowback upper. CMMG's 9 AR Conversion Magazine is a modified PMAG that seats into your AR15 mag-well and holds 10 rounds of 9mm ammunition. Its unique design allows it to feed any CMMG 9mm Radial Delayed Blowback upper receiver while maintaining last round bolt hold-open functionality.
