CMMG PISTOL, BANSHEE, Mk4, 5.7X28MM, 5″

PISTOL, BANSHEE, Mk4, 5.7X28MM, 5″

What many might consider the all-star of personal defense weapon calibers, 5.7x28mm has cemented itself as a greatly effective round with less recoil than 5.56mm at closer ranges. With just a 5” barrel this ultra-compact BANSHEE™ will fit almost anywhere you need it. If you’re not fond of pistol magazine-fed ARs don’t worry, this BANSHEE is built on our Mk4 – AR15 platform which uses a standard AR15 lower receiver and our new and improved 5.7x28mm AR conversion mags.

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.
