PISTOL, BANSHEE, Mk57, 5.7X28MM, 5"

5.7x28mm has quickly become the personal defense weapon caliber of choice for many. Offering near .22 LR levels of recoil and performance that rivals 5.56mm at close range it’s no surprise why. Even with a 5” barrel this BANSHEE™ sacrifices nothing when it comes to features. The Mk57™ platform is designed to use FN®* Five-seveN®* pattern magazines and still offers the full range of AR15 operational features like last round bolt hold open, and can utilize standard AR15 triggers.

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.
