Boonville, MO (November 16, 2021) – CMMG is proud to announce the release of the FourSix, the first-ever AR to hit the civilian market that’s chambered in 4.6x30mm. With an impressive 40-round magazine capacity, light recoil, and great penetration at close distances, CMMG’s FourSix is here to reimagine the Personal Defense Weapon.
CMMG’s FourSix is built on the company’s BANSHEE™, Mk4 platform while pioneering new technologies with its patent-pending Micro Gas Block and patent-pending CMMG 40RD 4.6x30mm Magazine. It comes standard with an 8-inch barrel and features AR15 controls and modularity. The BANSHEE’s lightweight and compact design pairs well with the soft-shooting 4.6x30mm cartridge to create a very controllable and portable firearm for almost any shooter. Best of all, the patent-pending CMMG 40RD 4.6x30mm Magazine will seat into any standard AR15-sized magwell, which means users can pair their existing AR15 lower receiver with a CMMG FourSix upper receiver and 4.6x30mm magazine.

“The firearms community has always been interested in the benefits of the 4.6x30mm round due to the popularity of the HK MP7 and its ability to be an effective tool in close-quarter combat situations, yet civilians are unable to get their hands on an MP7,” said Chris Reinkemeyer, CEO of CMMG. “The FourSix was created out of necessity to offer a solution for the civilian community to exploit the benefits of the 4.6x30mm cartridge while using familiar AR modularity.”
The 4.6x30mm round is best known for its superior penetration at close distances and for its extremely flat-shooting ballistics out to 150 yards. With its lightweight characteristics and relatively small dimensions, the 4.6x30mm cartridge allows the shooter to carry more ammo, which means more follow-up shots when needed most. The soft recoil, combined with a modified direct-impingement operating system, allows users to make rapid shots down range and on target.
First introduced in 1999, the 4.6x30mm cartridge is known for its pairing with the Heckler & Koch MP7. By design, the 4.6x30mm is a relatively small and lightweight cartridge with minimal felt recoil meant to compete with the 5.7x28mm. There has never been a 4.6x30mm chambered firearm released in the U.S. market – until now.
