The Benelli M2 American Series is a semi-automatic hunting shotgun chambered in 12 gauge. The American Series is the economically priced version of the M2 Field. It lacks a ComforTech recoil pad, but has a mid bead sight as well as a red bar front sight.

Like the standard it also uses Benelli’s Inertia Driven System uses recoil energy to cycle the action. The bolt is semi-fixed until the backwards force, vibrating through the gun, arrives to the bolt housing, the vibration rattles the bolt and it slides back. As it travels back it pushes against the inertia spring and once compressed all the way, the spring pushes back launching the bolt forward. This system is used instead of letting gas or the initial explosion drive the bolt back. And, since the gases can’t seep through into the chamber there won’t be any carbon-build up.
