Mossberg is introducing a twist on the reliable 590 pump-action shotguns, the new 590R and 590RM (Magazine Fed) 12-gauge shotguns with Rotary Safety Selector and AR-style ergonomics. New features on these shotguns include a redesigned, user-serviceable fore-end, integrated barrel/single heat shield and an ambidextrous, rotary safety selector. Four models are available, including two standard offerings and two magazine-fed versions using the first production double-stack magazines for pump-action shotguns.
Shared features of older models of the 590 and the new 590R include non-binding twin action bars, positive steel-to-steel lock-up, anti-jam elevator, dual extractors and aluminum receiver that is drilled and tapped to mount an optic.
Introduced in 2018, the Mossberg 590M shotgun shares key features with the new 590RM. At the core is the detachable magazine’s integral stabilizing ribs which engage the magazine directly with notches that are engineered into the receiver for a positive lock-up. The lever-style magazine release button and mounting guide are positioned in front of the trigger guard for ambidextrous access. Accessory magazines are available in 5-, 10-, 15- and 20-round capacities.
Mossberg 590R and 590RM Features:
- Ambidextrous, rotary safety selector with protective guard that can be reached without breaking grip.
- Mossberg-designed stock with five positions of adjustment (12 to 15.25 inches), interchangeable recoil pad, and two-sided QD cups. The front QD cup is located on the magazine cap.
- Stock/Base Adapter is compatible with other grip designs and accepts most mil-spec stocks.
- Magpul MOE+ pistol grip.
