North Haven, CT – Following the unprecedented success of the 590 Shockwave 12-gauge pump-action firearm, Mossberg announces the release of a 20-gauge version of the 590 Shockwave. Featuring a 14-inch barrel, “birds head” pistol grip and an overall length of 26.4 inches, the 590 Shockwave does not fall under the purview of the National Firearms Act (NFA) and does not require additional paperwork or the payment of a tax stamp for transfers. Federal Law does require the purchaser of this firearm to be 21 years of age. And coinciding with the announcement of this new 590 Shockwave, Mossberg is pleased to announce that the 20-gauge versions are already in production and shipping to wholesalers.
Based on the 590 pump-action design, the 20-gauge version of the Shockwave required an engineering redesign as this is the first time that Mossberg has offered the 590 platform in a smaller gauge. In addition to a scaled-down receiver, the cob-styled, tactical forend was reduced in overall size. Weighing in at a mere 4.95 lbs, this compact 20-gauge firearm combines the field-proven design of Mossberg’s legendary pump-action platform with the innovative Raptor® pistol grip from Shockwave Technologies; strapped forend for safe, controlled handling; and 6-round capacity.
At the core of the 590 Shockwave is Mossberg’s field-proven design which includes non-binding twin action bars; positive steel-to-steel lock-up; an anti-jam elevator; dual extractors; and Mossberg’s universally-recognized, ambidextrous top-mounted safety. The lightweight receiver is constructed of anodized aluminum and is drilled and tapped for ease of adding an optic or accessories. The magazine tube features a convenient clean-out cap. This 20-gauge is 2 ¾ and 3-inch capable with 6-round total capacity and features a 14-inch, heavy-walled barrel with bead sight and matte blue finish. Rear and magazine cap sling swivel studs complete this compact package.
The “bird’s head”-shaped pistol grip from Shockwave Technologies provides this 590 with its distinctive name. The Shockwave Raptor grip features an enhanced textured finish, allowing for maximum control while minimizing felt recoil. The grip is constructed of durable, glass-filled polymer with non-reflective, black finish and overall length of 5.25 inches.
Only Mossberg, a leader in the firearms industry and the world’s largest pump-action shotgun manufacturer, can offer a MilSpec 3443-approved pump-action platform (the only shotgun manufacturer to pass these endurance, accuracy and quality tests) in a 14-inch barreled non-NFA firearm. Now available in 12 and 20-gauge versions! For more information on the 590 Shockwave and other compact 500®/590A1™ offerings, please visit www.mossberg.com.
