Press Release

New Haven, CT- 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.”
