The Mossberg® FLEX™ 590® Tactical Pump-Action Shotgun features Mossberg's TLS, Tool-less Locking System, that enables shooters to rapidly switch stocks, forends, and recoil pads, using a single receiver as the core component for wide array of shotgun configurations. All FLEX?TLS components mount and remove from the gun in seconds—without tools. The FLEX 590 tactical shotgun features an 20" cylinder bore barrel with a bead sight and an 6-position, adjustable stock with a full pistol grip. A Tri-rail tactical forend allows further customization with the attachment of aftermarket tactical accessories. An anti-reflective finish on the barrel, receiver, and magazine tube resists corrosion, as well as aids in concealment. The U.S. Military's choice of Model 590 pump shotgun for combat attests to the design's reliable function and durability. The Model 590 pump-action shotgun uses dual action bars, dual extractors, an anti-jam shell elevator, and a large locking lug for a solid steel-to-steel connection between the bolt and barrel. Shooters can reach the top-mounted safety quickly with the thumb of either hand, making it naturally ambidextrous. The Model 590's simplistic design makes fieldstripping the action easy by tapping out a single pin, and the magazine cap-nut removes for cleaning the spring, shell follower, and any debris in the mag tube. The Model 590 cycles 2-3/4" and 3" shells interchangeably.
