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.
Easily convert your existing 5.56 PMAGs to shoot 9mm. CMMG’s 9 AR Conversion Magazine Adapter installs into a Magpul PMAG™
(Gen 2/3) magazine body. It comes standard with a 10-round capacity but can be easily modified to hold 15, 20 or 30 rounds of 9mm ammunition.
CMMG offers a complete line of firearms that are designed for the 9 AR Conversion Magazines and are available in RESOLUTE and BANSHEE configurations. Each is built using a CMMG Mk4 (AR15) lower receiver and a dedicated 9mm upper receiver featuring CMMG’s Radial Delayed Blowback operating system.
