Product Overview
The CMMG Mk57 BANSHEE is an AR-style pistol chambered in 5.7x28mm FN and built around CMMG’s radial delayed blowback operating system. Its eight-inch 4140CM SBN barrel is threaded 1/2x28 and paired with a CMMG ZEROED linear compensator. The Mk57 platform accepts FN Five-seveN pattern magazines while retaining familiar AR-style controls, including last-round bolt hold open. A billet 6061-T6 aluminum upper receiver, forged 7075-T6 aluminum lower receiver, EML7 M-LOK handguard, ambidextrous charging handle, and 60/90-degree safety selector provide a versatile configuration for range use and close-range defensive applications. The top Picatinny rail supports the addition of a compatible optic.
