Benelli MR1

Benelli MR1 guns self defense are chambered in 5.56 mm NATO (.223 Remington) and use the battle-proven Auto Regulating Gas Operated (ARGO) system, the same system developed by Benelli for the M1014 (M4) and used for over a decade. It features a stainless steel, self-cleaning piston that operates directly against the rotating bolt, a piston-driven system incorporates a gas port located just forward of the chamber, where the gases are hotter and cleaner, resulting in less fouling and more reliable cycling. The Benelli MR1 comes standard with a five-round magazine. The MR1 can also accept standard M16 magazines. Optional Picatinny front rail kit with two side rails and a lower rail is available for mounting a laser aiming device, front handle, illuminator and other accessories
