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. The 9 AR Conversion Magazine is a modified PMAG that seats into your AR15 mag-well and holds up to 30 rounds of 9mm ammunition.


9 AR Conversion Magazines allow you to pair your AR15 lower receiver with CMMG’s Radial Delayed Blowback operating system, which has quickly earned a reputation as the superior operating system for pistol caliber carbines (PCC’s).  Unlike typical direct blowback systems, Radial Delayed Blowback uses a bolt that is forced to rotate and unlock before cycling.  This delay allows CMMG to use a lighter buffer and carrier than a direct blowback, resulting in less felt recoil than the typical PCC.
