Initially originated for the .45 ACP MKG platform, CMMG has seamlessly extended our radial delayed Blowback system throughout our lineup of pistol calibers

This incorporation has led to the development of pistols and rifles characterized by a milder recoil impulse and decreased bolt weight in contrast to conventional straight Blowback systems

Features

Rapidly emerging as the caliber of choice for personal defense weapons, the 5.7 x 28 mm has captured the preferences of many. Delivering recoil levels akin to 0.22LR and performance that rivals 5.56mm at close distances, its popularity is well-founded. Even with a compact 5 inches barrel, the BANSHEE in this caliber maintains an array of features. The Mk57 platform is purposefully designed to accommodate FN Five-seven pattern magazines, while retaining the complete spectrum of operational attributes inherent in the AR15 system, including last round bolt hold open and compatibility with standard AR15 triggers. Presented in a variety of Cerakote finishes, the BANSHEE series epitomizes innovation among contemporary AR pistols and SBRs. From the swift deploying RIPBRACE to the artfully designed receivers and EML handguards, each BANSHEE is meticulously crafted to serve as a reliable and steadfast personal defense companion. Augmented by EML4 handguards featuring M-LOK slots at 3, 6 and 9 O'clock positions, accompanied by a full length picatinny top rail for accessory placement and an integrated handstop, the BANSHEE ensures ample room for your essential attachments.
