The M2-G1 is Benelli's gas-operated tactical shotgun built around the Rear Piston Operated (R.P.O.) system: dual pistons collecting gas nearer the chamber, with the recoil spring isolated in the stock. This listing is the fixed-stock, standard-grip configuration — Anodized Gray receiver, Matte Blued 18.5" barrel, Black Synthetic stock, 7+1 capacity, chambered for 2¾" and 3" 12-gauge shells. This listing is for Benelli item 11611 only. Benelli item number 11611, UPC 650350116113.

Rear Piston Operated (R.P.O.) Gas System

Unlike traditional gas guns that put the operating system forward on the magazine tube — where valves and the recoil spring sit in fouling, carbon, moisture, and debris — Benelli places the R.P.O. system closer to the receiver. Gas is collected nearer the chamber, where pressure is stronger and combustion gases are cleaner. Dual pistons drive the action, and the recoil spring is housed in the stock, kept clear of the operating gases. Benelli rates the M2-G1 platform for a 10-year warranty and positions it as a cleaner-running, duty-ready gas shotgun with lower maintenance than forward-mounted designs.
