Benelli's new autoloading R1 Rifle, while generations removed from the old U.S. Carbine, utilizes the gas-operated "short punch" system pioneered by Carbine Williams, known for designing a groundbreaking autoloading carbine while in prison. The reliability of the R1's Auto Regulating Gas Operated system has been proven in the M1014 military shotgun and has been adapted for centerfire rifle cartridges with a three-lugged rotary bolt. The rifle's gas cylinder is positioned just in front of the chamber allowing for short operating rods and reduced recoiling mass. The AirTouch checkering pattern takes advantage of the molding characteristics of the polymer used in Benelli stocks and forends to create a surface that gives a superior grip without being overly rough to the ungloved hand. The Benelli R1 Centerfire Rilfe has the ComforTech synthetic stock. The 20-inch barely is nicely blued and calibered for .30-06 Springfield ammunition.
