<p>The Benelli M4 Tactical Semi-Auto Shotgun with Tactical Stock sets the standard that hard-use shotguns are measured by. The M4 features A.R.G.O., an auto-regulated, piston-driven, gas operating system. Benelli's ARGO mechanism simplifies the design by eliminating complicated linkages and heavy parts found in other semi-auto shotgun designs. The auto-regulating gas system is designed to handle field loads to hard-hitting buckshot with no needed adjustments. A drilled and tapped receiver is topped off with a Picatinny optics rail and LPA ghost ring sight set. The Benelli M4 Tactical Shotgun comes with a synthetic buttstock, which features a sturdy recoil pad to reduce felt recoil and muzzle rise considerably. 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 trigger guard ensures safe operation. The Benelli M4 is an ideal home defense shotgun and commonly selected for use in law enforcement.</p> <ul> <li>Operates by unique A.R.G.O. system</li> <li>Handle everything from field loads to 3</li> <li>Synthetic buttstock</li> <li>5.25 Picatinny rail</li> <li>Ghost ring sight set</li> <li>Includes 1 modified choke tube</li> </ul>
