Introduced in 2004, the original Benelli M2 quickly established itself as one of the most respected semi-auto shotguns in the world. Now, the Benelli M2-G1 Semi-Auto Shotgun with Standard Stock is here to set the new benchmark for reliability and performance in a tactical platform. The Benelli M2-G1 Shotgun is built around the all-new Rear Piston Operated (RPO) system to provide cleaner operation, better control, and unflinching durability. Unlike traditional forward-mounted gas systems that introduce fouling into the operating components, the M2-G1's dual short-stroke pistons are positioned closer to the chamber where energy can be managed more efficiently. By collecting the gas and isolating the recoil inside the stock, the M2-G1 reduces fouling and allows for extended operation without cleaning. Aside from its innovative operating system, the shotgun features a fixed synthetic stock that provides a stable platform along with oversized operating controls that are easy to manipulate in stressful scenarios. The M-LOK forend provides a solid platform for accessories, while ghost ring sights deliver reliable targeting right out of the box. Aided by its 7+1 round capacity, the Benelli M2-G1 is a cleaner, more refined tactical shotgun built to perform under pressure.
