Built with a 5” nitride-finished barrel this BANSHEE™ chambered in 9mm is among the shortest, most compact ARs CMMG® has to offer. Capitalizing on our reputation for innovation, the MkGs platform uses the always popular 9mm double stack Glock-pattern magazines.

Available in a range of cerakote finishes, the BANSHEE series represents the most innovative AR pistols and SBRs available today. From the quick deploying RIPBRACE®, to the stylized receivers and EML™ handguards, every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. New EML4 handguards feature M-LOK® slots at 3, 6, & 9 o’clock positions and a full length picatinny top rail for accessories as well as an integrated handstop.
 
Radial Delayed Blowback™ Operating System
Originally developed for the .45 ACP MkG platform, CMMG has adapted our Radial Delayed Blowback system across our pistol caliber lineup to create pistols and rifles with a softer recoil impulse and reduced bolt weight compared to traditional straight blowback systems.
