ACCOKEEK, Md. -- Benelli's latest consumer offering--the MR 1 rifle--uses the ARGO (Auto-Regulating-Gas-Operated) system developed for the M1014 rifle used by the United States Marine Corps.
The MR 1, chambered for 5.56mm NATO (.223 Rem.), has military-style aperture sights adjustable for windage and elevation in the field, using only a cartridge rim. A Picatinny rail allows mounting of both conventional and night-vision sights, while retaining metallic-sight capability.
All steel parts are black phosphated, and aluminum parts are hard-anodized in a matte finish for low visibility and corrosion resistance.
The Benelli MR 1 carbine comes standard with a five-round magazine, and can also accept standard M16 magazines. An optional Picatinny tri-rail forend kit is available for mounting a laser aiming device, front handle, illuminator and other accessories.
The MR 1 features a stainless steel, self-cleaning piston that operates directly against the rotating bolt. This piston-driven ARGO 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 company says.
