Description: CMMG 5.7 AR Conversion 40 Round Magazine, 5.7x28mm. This 40 round 5.7x28mm CMMG AR conversion magazine is constructed of a black polymer and manufactured for converted AR-15 rifles that specifically have an attached Radial Delayed Blowback upper receiver installed on the AR lower. This conversion magazine is a modified PMAG that seats into your AR-15's mag-well and is capable of holding 40 rounds of 5.7x28mm ammunition. Featuring a unique design, this mag is able to feed any CMMG 5.7x28mm Radial Delayed Blowback upper receiver while maintaining last round bolt hold-open functionality.

CMMG's 5.7 AR Conversion Magazine holds 40 rounds of 5.7x28mm and fits in any standard AR15 lower receiver. To use, simply attach a CMMG 5.7x28mm Radial Delayed Blowback complete upper receiver to an existing AR15 lower. Then, insert CMMG’s 5.7 AR Conversion Magazine to safely feed 5.7x28mm ammunition. CMMG recommends using a standard carbine buffer and action spring to reliably cycle the action in this configuration. The 5.7 AR Conversion Magazine also retains last round bolt hold-open functionality, allowing for faster reloads. Designed for use with CMMG 5.7x28mm Radial Delayed Blowback upper receivers, on an existing milspec AR15/M16 lower receiver.

*Please note, this magazine is for AR-15 platform rifles that have been properly converted and capable of firing 9mm ammunition via the CMMG Radial Delayed Blowback upper.
