CMMG MK4 Banshee Semi-Automatic Pistol 4.6x30mm 8" Barrel (1)-40Rd Magazine Burnt Bronze Polymer Finish

With an impressive 40-round magazine capacity, light recoil, and great penetration at close distances, the CMMG FourSix is here to reimagine the Personal Defense Weapon. Not only is the FourSix the first AR chambered in 4.6x30mm, but it is also the first 4.6x30mm firearm ever released to the U.S. civilian market!

What is 4.6x30mm?

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.

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.

Available in a variety of Cerakote finish options, the BANSHEE series represents the most innovative AR pistols and SBRs available today. Every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. With full-length M-LOK slots on both sides and the bottom of the handguard as well as M-LOK between the top Picatinny rail sections, you’ll always have enough space for those must-have accessories.
