 A combat carbine has to perform the first time, every time. The ultra-reliable ARGO (Auto-Regulating-Gas-Operated) system used by the U.S. Military has been incorporated into the new Benelli MR1 and now can be the centerpiece of an effective home defense plan. The MR1 rifle, Benelli’s latest offering, is chambered in .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 ghost ring 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 phosphate and aluminum parts are hard-anodized in a matte finish for low visibility and corrosion resistance. The Benelli MR1 carbine comes standard with a five-round magazine, and can also accept standard M16/AR15magazines. An optional Picatinny tri-rail fore-end kit is available for mounting a laser aiming device, front handle, illuminator and other accessories.

The MR1 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 ARGO system exceeded the military requirements without malfunction. The result is a Benelli carbine with Marine-tough reliability able to function under the harshest conditions.

“The MR1 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 MR1.”
