CMMG® is proud to announce the release of the FourSix™, the first ever AR to hit the civilian market 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.

The 4.6x30mm round is best known for its superior penetration at close distances and also 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.

CMMG’s FourSix is built on the company’s BANSHEE™, Mk4 platform which features AR 15 controls and modularity. Best of all, the patent pending CMMG 40RD 4.6x30mm Magazine will seat into a standard AR 15-sized magwell, which means users can pair their existing AR15 lower receiver with a CMMG FourSix upper receiver and magazine.

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. The FourSix operates on a modified direct impingement system while offering Last Round Bolt Hold Open.

First introduced in 1999, the 4.6x30mm 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. civilian market until now.

Ballistically the 4.6x30mm round is very similar to the 5.7x28mm round in the sense that it is a high velocity, flat shooting projectile that has great penetration, but where the 4.6x30mm will hold an advantage is in your pocketbook. Due to the difficult barrier of entry for ammo manufacturers, the 5.7x28mm round currently and will always cost more than the more affordable and easier to manufacture 4.6x30mm round.
