Mossberg Announces 590S Pump-Action Line

October 26, 2021

Mossberg unveiled the 590S line to a group of firearms industry media at legendary Gunsite Academy, where we had ample time to run the platform, (as well as the new Mossberg MC2sc pistol). I have plenty of experience with the 500/590 and Shockwave, and enjoyed experiencing Mossberg's upgrades and the evolution of the line. A standout feature is clearly the ability to cycle 1.75, 2.75 and 3-inch shotshells INTERCHANGEABLY and in any combination - no adapter needed. The 590S (model 51602) with M-LOK Forend, was another clear winner with ghost ring sight sights and the versatility of M-LOK for accessories. ~ GK

PRESS RELEASE

NORTH HAVEN, CT – O.F. 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. 

590S Pump-Action Shotguns (51603/51602) – Available in two configurations, the 590S with 18.5-inch barrel features a front bead sight and corncob forend, while the 20-inch version has an adjustable Ghost Ring sight, AccuChoke-compatible barrel and versatile M-LOK® compatible forend. MSRP:  $605 - $708

590S Shockwave Pump-Actions (51601/51600) – The compact bird’s head-gripped Shockwave versions come with a choice of 14.375 or 18.5-inch barrel lengths; front bead sight; and strapped, corncob-style forend for ease of control. MSRP:  $605
