The 590A1 is the ultimate in heavy duty, rugged, pump action shotguns. As a testament to its capabilities to withstand harsh and stressful environments, it is currently the pump action shotgun of choice for the U.S. Armed Forces. 

In addition to this, a multitude of proven Mossberg staples remain, including dual extractors, twin action bars, steel to steel lock-up and an anti-jam elevator, combining for one of the most impressively practical shotguns ever made. 

This model features XS ghost ring sights, a speedfeed stock and a railed forend.
