With an impressive 40-round magazine capacity, light recoil, and great penetration at close distances, the CMMG Banshee 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!
Available in a variety of Cerakote finish options, the Banshee series represents the most innovative AR pistols and SBRs available today. From the stylized receivers and EML handguards, 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.
