The M2 Tactical is a no-nonsense 12-gauge shotgun that police and military the world over reach for when the going gets tough. The M2 Tactical, like all Benelli semiautomatic shotguns is Inertia Driven®, which uses recoil energy to cycle the action. This eliminates all the problems associated with gas-operated systems, such as the necessity of frequent cleaning and the tendency gas-operated systems have for malfunctioning during adverse weather conditions. The M2 Tactical fires all 1 oz. or heavier 2¾" and 3" loads. The M2 Tactical features a fully adjustable ghost-ring aperture rear sight and military-style fixed-blade front sight or adjustable rifle sights. In addition the M2 Tactical comes with either a matte black synthetic stock with tactical pistol grip, or with a ComforTech® stock that reduces felt recoil by as much as 48%. The M2 Tactical is a shotgun you can bet your life on.
