SBR, BANSHEE, Mk57, 5.7x28mm, 5"

Interchangeability matters, that's why the Mk57(TM) is not only chambered in the same caliber, 5.7x28mm, as other popular PDWs and pistols, but the BANSHEE(TM) Mk57 SBR uses FN(R)* Five-seveN(R)* pattern magazines. Not only do shooters get more ways to use their mags, the Mk57 still brings the full set of AR15 features, making rifle operation second nature. With 5" barrel this is the smallest Mk57 SBR CMMGhas to offer.Available in a range of cerakote finishes, the BANSHEE series represents the most innovative AR pistols and SBRs available today. From the quick deploying B5 Systems Bravo Stock, to the stylized receivers and EML(TM) handguards, every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. New EML4 handguards feature M-LOKslots at 3, 6, & 9 o'clock positions and a full length picatinny top rail for accessories as well as an integrated handstop.With the wide range in ammunition available, and the option for suppressed operation, the available Action Tuning Kit will allow you to tune your system even more for added flexibility and smoother operation.Radial Delayed Blowback(TM) Operating SystemOriginally 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.
