Mossberg Introduces 590R and 590RM Shotguns w/Rotary Safety Selector

Written by Mossberg | Jan 10, 2025 9:57:10 PM

The ruggedly-built Mossberg 590® pump-action shotgun has been chosen for duty and home defense for decades for its reliability, performance, and wide range of configurations. This field-proven tactical platform continues to evolve and serves as an inspiration for Mossberg’s newest pump-action shotguns: introducing the 590R and 590RM (Mag Fed) 12-gauge shotguns with Rotary Safety Selector and AR-style ergonomics. New ground-breaking features include a redesigned user-serviceable forend; integrated barrel/single heat shield; and ambidextrous, rotary safety selector. Four models are available, including two standard offerings and two mag-fed versions, utilizing the first production double-stack magazines for pump-action shotguns.

Shared features of the 590 platform and the new 590R include non-binding twin action bars; positive steel-to-steel lock-up and anti-jam elevator; dual extractors; aluminum receiver; drilled and tapped receivers. And further enhancing the platform is a convenient clean-out magazine tube with cap for ease of maintenance.

Introduced in 2018, the Mossberg 590M Mag Fed shotgun shares key features with the new 590RM. At the core is the detachable magazine’s integral stabilizing ribs which engage the magazine directly to notches 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, 20-round capacities.

 

Key Features of the 590R and 590RM Pump-Action Shotguns:

  • Ambidextrous, rotary safety selector with protective guard that can be reached without breaking grip.
  • Mossberg-designed stock with five positions of adjustment (12 – 15.25 inches), interchangeable recoil pad, and 2-sided QD cups. The front QD cup is located on the mag cap.
  • Stock/Base Adapter is compatible with other grip designs. Accepts most Mil-Spec stocks.
  • Magpul® MOE+® pistol grip.
  • Compact, ergonomically shaped forend with new 4-piece attachment that is user serviceable.
  • 5-inch barrel with integrated heat shield that is removable (standard and stand-off versions).
  • Front M-LOK® adapter with dual sided accessory mounting slots at 3 and 9 o’clock positions.
  • Flat profile trigger with smooth, crisp break.
  • Top Picatinny rail for ease of adding optics. Optional Mapgul MBUS® 3 sights on select models.
  • Enlarged, beveled loading port with extended follower for ease of loading (590R only).
  • Elongated bolt release.
  • Electroplated internal and external receiver for durability and smoother finish.
