Description
Product Overview
The CMMG Banshee Mk57 is an AR-pattern pistol chambered in 5.7x28mm and built around FN Five-seveN pattern magazines. Its five-inch barrel is suited to compact defensive and close-range applications, while the Radial Delayed Blowback operating system helps reduce felt recoil and allows a lighter bolt than traditional straight-blowback designs. The Armor Black finish, stylized receivers, EML handguard, RIPBRACE, full-length top Picatinny rail, and M-LOK accessory slots provide a compact platform with familiar AR controls and flexible accessory mounting.
