The Best 9mm AR15 PDW? The CMMG Banshee SBR and DefCan Silencer [from Silencer Shop]

In this episode of TFBTV, James looks at the brand new CMMG Banshee. This is a 9mm SBR (short barrel rifle) PDW (personal defense weapon) AR15-type carbine that takes Glock magazines. In simpler terms, it’s a reeealllly tiny AR15 that uses the magazines from your Glock pistols. James also runs the CMMG DefCan-9 silencer on this diminutive blaster.


The press releases from CMMG are as follows:

CMMG has announced the addition of a new series of short barreled rifles (SBR’s) and AR Pistols that will be known as the BANSHEE line. The BANSHEE’s sleek new design sports the shortest barrels CMMG offers in 9mm, .45 ACP, 300 BLK and .22 Long Rifle. This ultra-compact and lightweight platform is extremely portable, making the BANSHEE a great option for close protection, home defense, plinking, competition shooting or any other application that benefits from the reduced size.

Each version of the BANSHEE sports CMMG’s new ambidextrous charging handle, as well as an ambidextrous sling plate and ambidextrous safety selector. The BANSHEE comes standard with CMMG’s Premier Cerakote finish, an RML M-LOK Hand Guard and a Magpul MOE Pistol Grip. The AR Pistol versions each come with a Tailhook Mod 2 Brace.

The SBR versions (all NFA rules apply) come equipped with a Magpul MVG Foregrip and will feature CMMG’s new RIPSTOCK. The RIPSTOCK is a new compact butt stock that is fully machined out of 6061-T6 AL and Cerakoted by CMMG. The RIPSTOCK features two of CMMG’s patent pending technologies: FASTBACK and P3. Thanks to FASTBACK Technology, users can simply pull straight back to extend the stock without worrying about a release lever like most AR butt stocks employ. It also features personal position presets (P3 Technology) that allow users to adjust a screw into one of five slots to ensure the stock extends to the same position each time.

The 9mm and .45 ACP BANSHEEs feed from factory Glock magazines and utilize CMMG’s patent pending Radial Delayed Blowback operating system. The benefit of the Radial Delayed Blowback system is that it allows CMMG to use a lighter buffer and carrier than the typical straight blowback design. This reduction in reciprocating mass ensures that both the 9mm and .45 ACP version of the BANSHEE are easily controllable.

CMMG’s DefCan suppressor line has a wide-range of offerings that will meet the needs of shooters from a variety of disciplines, ranging from personal defense, to the long-range shooters, to the casual plinkers. DefCan suppressors are not only optimized for decibel reduction, but are also lightweight, durable and being offered at an affordable price point.

“DefCan is an exciting new step for CMMG. Combined with our new line of BANSHEE SBRs, DefCan suppressors will give us a strong presence in the NFA market. Additionally, the DefCan suppressor line complements our current firearm product line-up very well and will be an integral part of our plans going forward,” said Chris Reinkemeyer, CEO at CMMG.

    Well it would be nice if these folks would make them with an ambi Mag release. Right now I can build my own if not I can get a scorpion or MPX. And since I have a butt load of Glock Mags I guess it is build my own!

    That stock system with the set screw is a fantastic idea. This also seems pretty snappy. I've only tried a couple PCC but they seemed quite slow to cycle and that was really annoying.
