Pistol, BANSHEE, Mk57, 5.7x28mm, 8", Pistol Tube

The hunt for your next personal defense weapon is over. Chambered in 5.7x28mm this Mk57™ BANSHEE™ utilizes an 8” barrel to maximize the full potential of the 5.7x28mm round as a close-range personal defense caliber. Built on the Mk57 platform, this BANSHEE accepts FN®* Five-seveN®* pattern magazines and features an intuitive oversized mag release. Rest assured that even with the use of pistol mags, conventional AR functionality like last round bolt hold open is here to stay in the Mk57.

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.

 

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.
