Converts Your Magazine to Shoot 9mm Ammunition

The CMMG 9 AR Magazine Conversion 9mm is a modified Magpul PMAG that fits perfectly into your AR15 mag-well and converts your magazine into 9mm caliber ammunition. It comes from the factory already installed Magpul PMAG for use in your standard AR lower with a CMMG 9mm upper receiver.

This conversion magazine makes it possible to shoot 9mm ammunition from your unmodified AR15 lower receiver when paired with a CMMG 9mm Radial Delayed Blowback upper.

Holds 30 Rounds of 9mm Ammunition

The CMMG 9 AR Magazine Conversion Kit holds 30 rounds of 9mm ammunition and features a last round bolt hold open for added functionality. It’s made compatible with standard carbine buffers and recoil springs, so you can easily build a 9mm PCC.

Its unique design allows it to feed any CMMG 9mm Radial Delayed Blowback upper receiver while keeping it small enough to stow away in a pocket of your jeans or backpack,
