ACCOKEEK, MARYLAND-- A combat carbine has to perform the first time, every time. The ultra-reliable ARGO (Auto-Regulating-Gas-Operated) system incorporated into the new Benelli MR 1 does it for the U.S. military, and now can be the centerpiece of an effective home defense plan. The MR 1 rifle, Benelli's latest offering, is chambered in 5.56mm NATO (.223 Rem.) and uses the battle-proven ARGO system-the same system developed by Benelli for the M1014 and used for over a decade in multiple conflicts by the United States Marine Corps.
The sights are a military-style aperture, 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 proven rotating bolt, thereby eliminating the need for complex linkages found on other inferior gas systems. This piston-driven system (ARGO), perfected by Benelli, 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. In function testing the MR 1 exceeded the military requirements without malfunction. The result is a Benelli carbine with Marine-tough reliability able to function under the harshest environmental conditions.
"The MR 1 is another great development, and certainly a major milestone for Benelli," said Stephen McKelvain, Benelli's VP of Marketing & Communications. "Any shooter who appreciates accuracy and reliability will have to own a Benelli MR 1."
