The CMMG 9mm AR Conversion makes it possible to shoot 9mm ammunition from your unmodified AR15 lower receiver when paired with a CMMG 9mm Radial Delayed Blowback Upper. CMMG's 9 Ar Conversion is inserted into a Gen 2 or Gen 3 Magpul PMAG. It seats into your AR-15 mag-well and holds up to 30 rounds of 9mm ammunition. Its unique design allows it to feed any CMMG 9mm Radial Delayed Blowback Upper Receiver while maintaining last round bolt hold-open functionality.
- Can be modified to hold 10, 20, or 30 rounds
- Last Round Bolt Hold-Open
- 9 ARC Internals to be put into Magpul PMAG (Gen 2 or Gen 3)
- Uses Standard Carbine Buffer and Action Spring
The 9 AR Conversion allows owners of standard M16/M4/AR15 to purchase a dedicated CMMG 9mm MkGs upper group (not compatible with other uppers). The 9 ARC and MkGs upper groups are designed to be compatible with M16/M4 full auto lower receivers.
