CMMG’s 9 ARC Magazine – Convert an AR15 to Shoot 9mm

Boonville, MO-(Ammoland.com)- CMMG Inc. innovates the AR platform yet again with the introduction of the 9 ARC Magazine. Developed in collaboration with Mean Arms, CMMG’s 9 ARC Magazine (10 or 30-round capacity) makes it possible to shoot 9mm from an AR15 lower receiver when paired with CMMG’s proprietary 9mm Radial Delayed Blowback BANSHEE or RESOLUTE upper.

The 9 ARC Magazine is ideal for those who have a registered SBR or full-auto AR15 lower receiver and want to shoot 9mm. It also offers an affordable way to train or enjoy an outing at the range by allowing users to shoot inexpensive 9mm ammunition while still maintaining the familiar furniture and controls on their existing AR15 lower receiver.

The process of converting an AR15 to 9mm is simple and quick. First, attach a CMMG 9mm Radial Delayed Blowback upper receiver to an existing AR15 lower. Second, insert CMMG’s 9 ARC Magazine to safely feed 9mm ammunition. CMMG recommends using a standard carbine buffer and action spring to reliably cycle the action in this configuration. The 9 ARC Magazine also retains last round bolt hold-open functionality, allowing for faster reloads.

9 ARC Magazine For those who have an abundant amount of Magpul PMAGs, CMMG will offer 9 ARC Magazine Adapters. The 9 ARC Magazine Adapters are installed into Gen 2/3 PMAG bodies to convert them to 9mm. The 9 ARC Magazine Adapters will be sold as single units, as well as in packs of three, and can be modified to hold 10, 15, 20 or 30 rounds of 9mm ammunition.

One the greatest benefits of using the 9 ARC Magazine is that it allows shooters to enjoy the advantages of CMMG’s patent-pending Radial Delayed Blowback operating system without the need for a proprietary lower receiver. Radial Delayed Blowback has quickly become the gold standard for pistol caliber carbines, primarily due to the reduction in felt recoil versus other direct blowback designs.

CMMG will offer a complete line of firearms in RESOLUTE and BANSHEE configurations that are designed for 9 ARC Magazines. Each is built with CMMG’s Mk4 lower receiver and a dedicated 9mm Radial Delayed Blowback upper receiver.

The MSRP for the 9 ARC Magazine is $44.95 and for the 9 ARC Magazine Adapter is $29.95. The three-pack of 9 ARC Magazine Adapters will retail for $79.95.

CMMG Inc will be exhibiting during the 148th NRA Annual Meeting, showcasing new products like the 9 ARC, .40 S&W BANSHEE and the highly anticipated .350 Legend. Come visit CMMG at booth #5463 to get hands-on experience with the new products and the award-winning Mk47. Also have a chance to meet competitive shooters Team Yackley and a special appearance by legendary UFC fighter Chuck Liddell on Saturday between 1:30pm – 2:30pm.

      1. Oh aren’t you cool, gotta point out little bullshit that no one gives a fuck about. You’re the type of person that needs to learn when to talk and when to just keep quiet.

        1. @Tyler Berry,

          And you’re the type of person who needs an education in manners, respect, decorum, and quite probably, a remedial English language course at your local community college!

          Those spewing four letter words without need, are those seriously lacking in cognitive abilities.

          Cheers

          1. Spot on! It’s pretty sad when these articles are published and they writer isn’t intelligent enough to match the right photo with his statement, it’s even sadder when some asshat bitches because a commenter corrects the writer. Tyler berry is one of those lazy jerks that doesn’t care about misinformation being spread.

    1. The only problem i have with banshee is there have been reports of them being unreliable for jhp. I believe also they have even said use with fmj ammo. A lot of people look at short ar9 and think home defense. Which I don’t think the feeding issue is just cmmg ar9s, a lot of variation is going on with the way barrels are cut with feed ramps. If i knew the banshee would eat everything id be on board. What’s your thoughts on jhp and ar9s?

        1. You’re talking apples and oranges. A PSA AR9 is NOT a conversion, it requires an AR9 lower which takes actual 9mm magazines.
