Mossberg Expands 590R Line With New Finishes and Features

Mossberg has expanded its 590R series with four new pump-action shotguns, each featuring Cerakote finishes in either Olive Drab Green or Flat Dark Earth. These finishes are applied to the receiver, barrel, heat shield, and magazine tube, giving the new models a rugged, weather-resistant appearance while maintaining the functionality the 590R platform is known for. In my World, O.D. Green guns are the best!
The updated 590R models continue to feature the rotary safety selector, a departure from the traditional tang safety found on many Mossberg shotguns. This design is aimed at improving ergonomics, especially for those using pistol grip configurations. To each their own, but I’m a fan of pistol grips on shotguns; I just feel that I’m more in control. Among the notable upgrades are a redesigned, user-serviceable forend, an integrated barrel and heat shield, and the ambidextrous rotary safety selector for more versatile handling.
Standard features across the lineup include non-binding twin action bars, steel-to-steel lock-up, dual extractors, and an anti-jam elevator. The aluminum receiver is drilled and tapped for optics, and the magazine tube holds 6+1 rounds. A clean-out cap is included for easier maintenance.
Key Features of the 590R 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.
- 18.5-inch barrel with integrated heat shield that is removable (standard and stand-off versions).
- 6+1 rounds magazine capacity.
- 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.
- Elongated bolt release.
- Electroplated internal and external receiver for durability and smoother finish.
