Developed in collaboration with Mean Arms, CMMG’s 9 AR Conversion magazine is designed to allow a standard M16/M4/AR15 lower to run 9 x 19mm Luger ammunition with the use of a CMMG 9mm Radial Delayed Blowback operating system upper group. The 9 AR Conversion magazine is not a .223/5.56 to 9mm conversion kit. The 9 AR Conversion allows owners of standard M16/M4/AR15 to purchase a dedicated CMMG 9mm upper group. The 9 ARC and 9mm Radial Delayed Blowback upper groups are designed to be compatible with any standard AR15 lower receiver. The 9 AR Conversion utilizes a MagPul PMAG® 30/AR/M4 GEN M2 MOE® magazine body.
NOTE: The lower receiver should run a standard carbine buffer and action spring for reliable functioning.
