The Mossberg 590RM Mag-Fed Stand-Off Pump-Action Shotgun performs well beyond the average pump gun, offering enhanced capacity and unique capabilities along with signature Mossberg reliability. First off, it feeds from the first production double-stack magazines made just for pump-actions providing a robust capacity. The barrel comes outfitted with both a polymer heat shield and a stand-off muzzle with glass-breaker. A Picatinny rail makes adding a red dot easy, and an enlarged, beveled loading port makes loading individual shells quick and easy. The 5-position stock provides the ideal fit with and without body armor and features an interchangeable recoil pad and 2 QD ports. The 590RM also features an ambidextrous, AR-style rotary safety selector.
