Mossberg & Sons, Inc., America’s oldest family-owned firearms manufacturer in the United States, continues its legacy of industry firsts with the introduction of the 590S Series of 12-gauge pump-actions; capable of cycling 1.75, 2.75 and 3-inch shotshells interchangeably, in any combination, without the use of an adaptor. The 590S Series includes two full-length stock options and two versions of the bird’s head-gripped Shockwave.

Based upon Mossberg’s legendary 500 pump-action platform, 590 tactical guns include non-binding twin action bars; positive steel-to-steel lock-up and anti-jam elevator; dual extractors; drilled and tapped receivers; and universally-recognized, ambidextrous top-mounted safety. Enhancing the decades-proven 500 platform is a convenient clean-out magazine tube with cap for ease of maintenance. Additional features of the 590S series include black synthetic stock and forend; cylinder bore barrel AccuChoke barrel on the 20-inch version); matte blue metal finish; sling swivel studs; and logo-engraved receiver on all models.

Key design changes of the 590S include a redesigned elevator and bolt slide combined with the addition of an energy-absorbing bumper. This patent-pending innovative platform allows the user to load their choice of shotshell length (1.75, 2.75 and 3-inch) and shotshell type for their specific shooting needs, and in any combination. Use of shorter shell lengths will also increase the overall capacity of the 590S.
