The M2-G1 is built to run cleaner and stay reliable when it counts. By collecting gas closer to the chamber and mounting the recoil system in the stock, it delivers smoother control and longer sustained performance than forward-mounted designs. The result is when it’s time to call the M2-G1 into action..

RPO -REAR PISTON OPERTATED
The Benelli M2-G1 introduces the innovative Rear Piston Operated (R.P.O.) system, a next-generation gas operating system engineered specifically for today’s tactical shotgun market. While the Benelli M4 and its combat-proven A.R.G.O. (Auto-Regulating Gas-Operated) system remain the benchmark for military-grade performance, the M2-G1 was developed to deliver a distinct advantage through cleaner operation, simplified maintenance, and exceptional long-term reliability.

5-POSITION TELESCOPING STOCK
The adjustable telescoping stock features five length-of-pull positions, allowing shooters to optimize fit, comfort, and control for maximum performance.

BEVELED LOADING PORT
An enlarged, beveled loading port improves reload speed and loading efficiency for tactical shooting and competition.

GHOST RING SIGHTS AND PICATINNY RAIL
Factory-equipped ghost ring sights and a Picatinny rail provide fast target acquisition and easy optic mounting for tactical applications.
