Convert Your AR to 9mm with CMMG 9 ARC Magazines

New from CMMG this week is their 9 ARC magazines and mag inserts, which make standard AR mags compatible with 9mm ammo.

To get a functional 9mm AR, all you need is a CMMG upper equipped with the company’s proprietary radial delayed blowback system and any standard AR lower.  Buy a CMMG 9 ARC mag or swap in the 9 ARC insert into your Magpul PMAG, load up with 9mm and you’re ready to rock n roll!

Training with your AR is now a whole lot cheaper.  What’s more, is that those of you who have jumped through the ATF hoops to acquire a full auto lower can also cash in on the fun if you purchase a CMMG upper and the ARC mags/inert.

Highlights:

• No Tools Required
• Up to 30-Round Capacity
• Last Round Bolt Hold-Open
• Uses Standard Carbine Buffer and Spring
• Compatible with CMMG 9mm Radial Delayed Blowback uppers only
• Great For Training

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 pistol caliber carbines (PCCs).

I just ran 500 rounds through my 9mm CMMG upper with a full auto lower. The recoil was somewhere just north of .22LR and the rate was very controllable. Why 500 rounds? Because that was all I had. I just kept smiling and reloading.

Want to give the 9 ARC a try? Look for them at cmmginc.com .  Complete mag is $44.95, and the insert for your PMAG is $29.95.
