CMMG Banshee Mk4 9mm Pistol 8″, Black

The CMMG® BANSHEE™ series has a number of 9mm AR pistols built on a few different platforms. The Mk4 platform this BANSHEE is built on has a standard AR15-pattern lower receiver and utilizes our 9mm AR conversion magazines. While not only having the same manual of arms as any AR15, you can convert your existing stash of PMAGs to 9mm using our 9 AR conversion adapters.

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. Check out our CMMG Resources article & video to learn more about what sets Radial Delayed Blowback apart.
