CMMG has taken 5.7x28mm to a whole new level with the release of the 5.7 Banshee and AR Conversion Magazine.

CMMG reports that pistol-caliber AR pistols are its best performing product segment right now. The 10 mm Banshee 300 is an AR pistol with an abbreviated 8" barrel and CMMG’s ATF-compliant RipBrace.

CMMG Inc. announces the highly anticipated 10mm BANSHEE with its (patent pending) Radial Delayed Blowback operating system and Last-Round Bolt Hold Open.

The Mk57 Banshee pistol, featured here, operates different than the typical Stoner, gas-operated design.

CMMG recently unveiled a new line of super-compact AR15 style pistols and short-barreled rifles chambered in FN 5.7x28mm.

CMMG's MkG Guard pistol-caliber rifle is now safety certified to shoot the potent 450 SMC cartridge.
