<p>The Benelli M4 Tactical Semi-Auto Shotgun has been battle-proven for reliability around the world by the U.S. Marine Corps since 1998. The Benelli M4 semi-auto shotgun operates by a unique, Auto-Regulating Gas-Operated (A.R.G.O.) system, featuring dual stainless steel, self-cleaning, pistons that bear directly on the bolt assembly. Benelli's ARGO mechanism eliminates the more complicated linkages and heavier parts of other semi-auto shotgun designs, to produce a relatively simple and robust action. The auto-regulating gas system is designed to handle everything from field loads to hard-hitting 3 buckshot without the need of adjustments. The Benelli M4 Tactical Shotgun comes with a pistol-grip synthetic buttstock, made to withstand any environment. The pistol-grip is made from a rubber/poly blend and the stock features a sturdy recoil pad, that together with the gas operation, cut recoil and muzzle lift considerably, allowing the shooter to stay on target and deliver rapid follow up shots. An under-barrel sling point at the front of the handguard and one on each side of the stock facilitate ambidextrous sling attachment. The M4 shotgun comes with an 18.5 barrel with 1 screw-in choke tube (modified), and a 5-round magazine tube. A crossbolt safety behind the triggerguard ensures safe operation. The Benelli M4 Tactical Shotgun comes with a fully adjustable LPA ghost ring rear sight and a white dot front blade inside protective ears for quick target acquisition. A 5.25 Picatinny rail allows user to mount additional scopes and optical sights. The Benelli M4 is an ideal home defense shotgun, law enforcement shotgun, or a rugged all-purpose shotgun to carry in bear country.<br> Manufacturer model #: 11707.</p> <ul> <li>Operates by unique A.R.G.O. system</li> <li>Handle everything from field loads to hard-hitting 3</li> <li>Pistol-grip synthetic buttstock</li> <li>5.25 Picatinny rail</li> <li>Includes 1 choke tube</li> </ul>
