Mossberg's 590 special purpose is the shotgun you can count on to provide high security without high maintenance. The 500 and 590 are the only pump-action shotguns ever to pass all stringent U. S. Military Mil-Spec 3443 standards. In addition, every Mossberg Special Purpose Shotgun features a host of proven Mossberg features like an anti-jam elevator, twin action bars, dual extractors for reliable feeding, and positive shot shell extraction and ejection. Rugged black synthetic stocks and drilled and tapped receivers for trouble-free scope base and optics installation make this an easy gun to rely on. With a 20" cylinder bore barrel and an 8-shot magazine tube, the Special Purpose has plenty of firepower. This variant has a heat shield on the barrel and a front bead sight.
