MR1 guns are chambered in .223 Remington and use the battle-proven Auto Regulating Gas Operated (A.R.G.O.) system—the same system developed by Benelli for the M1014 (M4) and used for over a decade in multiple conflicts by the United States Marine Corps. Built to the same tough military specifications and embodying the solid reliability that the U.S. Marines rely upon. It 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 gas systems. This piston-driven system, 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. The result —tough reliability and the ability to function in the harshest environmental conditions.
MR1 is the semi-automatic rifle that better symbolizes all that Benelli energy, versatility and reliability. It aims to provide a firearm combining the benefits of military models with those of civilian guns. The gas system, the safe hardwearing locking system, and the use of high-quality materials constructed in compliance with the strictest industrial parameters mean that MR1 can guarantee high performance in a .223-caliber Remington.
