Essential design, simple construction, easy maintenance and mechanical precision for maximum strength and reliability.

The cleverness of the Benelli System lies in the rigor of its design, constructional simplicity and ease of maintenance. There are three main components: the bolt, that acts as an inertial mass and slides freely along guides made in the sides of the receiver, the locking head and the large free spring, mounted on the bolt.Its operations is ingenious and efficient. While the bolt assembly moves into the firing position, the locking head pin movesalong a shaped guide inside the bolt to engage the locking head.When the trigger is pulled, all the components of the shotgun,with the exception of the bolt, move backwards. At the same time,the inertial spring is compressed between the head of the bolt and the body of the bolt itself. The cartridge drop lever rises to allowthe cartridge to move from the magazine to the firing chamber.Towards the end of the recoil cycle, the pressure inside the chamberreaches a safe level and the backward movement of the shotgun slows down. Then, the heavy inertial spring pushes the bolt assembly backwards, releasing the revolving head of the bolt and extracting the cartridge fired from the chamber, pushing it against the ejector. When the empty cartridge leaves the receiver, the energy developed by the moving bolt assembly rearms the hammer and compresses the recoil spring inside the stock. Following this, the recoil spring pushes the bolt assembly forwards, in this way raising the shell forwards into the  correct position and putting a new cartridge into the chamber. The brevity and ease of these movements together with mechanical precision and constructional simplicity guarantee an operating cycle which will not alter or jam, offering maximum resistance and extreme reliability.
