Like benelli's M 1 and M3, benelli's M2 is characterized by its recoil system-inertial recoil, which was developed and patented by benelli in the early 1960s. The system relies on the backward movement of the shotgun below recoil. The system has the advantages of high reliability and easy maintenance. Due to the problem of inertial recoil system, benelli M2 needs a lot of high-pressure propellant gas to ensure its normal circulation. Similarly, a heavier charge will make the gun complete the firing cycle in a shorter time. The gun is also equipped with a recoil reduction system patented by benelli, which can reduce the recoil by 48% and the muzzle lift by 65,438+05% and increase the firing rate by 69%.

The buffer spring is accommodated in the stock like Browning Auto-5 or Remington 1 100; Comprehensive factors, shotguns can only be fired below the stock.

The standard benelli M2 features aluminum alloy, built-in tubular magazine and convertible standard shotgun stock or pistol grip stock. Benelli M2 is suitable for using traditional notched mechanical doors or ghost ring doors. In addition, tactical accessories such as laser sights or tactical lights can be installed.
