Description

CMMG’s Mk57 PSB AR pistol is chambered in 5.7X28mm. The Mk57 is fed from FN FiveSeven-style magazines and uses CMMG’s patent pending Radial Delayed Blowback operating system that easily handles the 5.7X28mm cartridge while simultaneously keeping weight and felt recoil to a minimum. It also features a patented, dual-pinned, fully machined bolt catch linkage, making operation both easy and intuitive. The Mk57 has a forged upper and billet lower 7075-T6 aluminum receiver with CMMG’s single-stage, mil-spec style trigger. The Mk57 PSB features a KAK Shockwave Stabilizer Blade and tube, Magpul MOE pistol grip, and RML7 handguard with a top rail and M-Lok configuration at the 3, 6, and 9 o’clock locations. It is 25 in length as configured with brace in mid-position. This model has a Black Anodized receiver and handguard finish, 8″ barrel with an A2 compensator. The Mk57 is threaded 1/2-28 to accept the most common 5.7 rated suppressors.
