JUST RELEASED: Mossberg Shockwave 590M

by Pete

Mossberg has just signaled the commercial availability of their latest Shockwave firearm chambered in 12 gauge scattergun bliss. The Shockwave 590M was announced earlier this year leading up to the SHOT Show in Vegas, sporting magazines over the more traditional tube-fed Shockwave. In case you’ve been living in a cave, had a While You Were Sleeping event, drafted into the Space Force and immediately deployed to the outlying terraformed planets or otherwise refuse to live in the modern world, the Shockwave is not a Shotgun nor is it an NFA controlled weapon. Although chambered In a gauge and not a caliber and having a barrel shorter than 18”, the combination of overall length and having no shoulder stock leaves the 590M categorized strictly as a firearm. Cash and carry… in most places.

The press release and details can be found below.

MSRP: $729

Mossberg Introduces Shockwave 590M 12-Gauge Pump-Action


Mag-Fed Versatility in a Compact Pump-Action

North Haven, CT – Combining the convenience and adaptability of a mag-fed shotgun with a “Non-NFA” pump-action platform, Mossberg is proud to introduce the 590M Shockwave 12-gauge firearm with 15-inch barrel, pistol grip and the world’s first double-stack, 10-round shotgun magazine. And for greater versatility, optional 5, 10, 15 and 20-round capacity magazines are sold as accessories. This compact 12-gauge is classified by the BATFE (Bureau of Alcohol, Tobacco, Firearms and Explosives) as a “Non-NFA Firearm,” requiring no tax stamp for transfers.

Based upon Mossberg’s proven pump-action platform, standard features of the 590M Shockwave include non-binding twin action bars; positive steel-to-steel lock-up; dual extractors; anodized aluminum receiver drilled and tapped for convenience of adding optics; 15-inch heavy-walled barrel; convenient cleanout magazine tube; and universally-recognized, ambidextrous top-mounted safety. With the included 10-round magazine, these 12-gauge 2.75-inch pump-actions have a total round capacity of 10+1.

Unique to the Shockwave platform, and providing its novel moniker, is the Shockwave Technologies Raptor® pistol grip.

This well-designed pistol grip features an enhanced textured finish and has a “bird’s head” shaped-profile, allowing for maximum control while minimizing felt recoil. The grip is constructed of durable, glass-filled polymer with non-reflective, black finish and has an overall length of 5.25 inches. Completing the furniture package for the 590M Shockwave is the cob-styled, tactical forend which is strapped for greater control and smoother operation.

At the core of the 590M Shockwave are the magazine’s integral stabilizing ribs which engage the magazine directly to notches machined into the receiver, ensuring a positive lock-up. The all-steel, heated-treated magazine release button and housing are optimally-positioned in front of the trigger guard for convenient, ambidextrous access for unloading and reloading. The location of the mag release does not interfere with cycling of the action. The well-executed design allows for proper balance with a full-magazine located at the center of gravity point.

As a first for mag-fed shotguns, the 590M design features a patented double-stack magazine constructed with hardened-steel feed lips, over-molded steel shell ramps and an anti-cant, rounded follower to ensure reliable feeding. Additionalfeatures include an easy-grip, molded external shell; proprietary self-lubricating polymer magazine body; heavy-duty ASTM-A-228 music-wire magazine spring for prolonged service life; removable floor plate for ease of cleaning; and durable black oxide finish on the steel components. This proprietary double-stack magazine design provides greater capacity in less magazine length versus competitor’s single stack magazines.

The 590M Shockwave features an overall length of 27.5 inches, recoil-taming pistol grip (not designed to be shoulder-mounted), compact 15-inch barrel length and the convenience of magazine-feeding. By definition, the Shockwave platform is a “firearm” under the Gun Control Act of 1968 (GCA), and is not subject to the provisions of the National Firearms Act (NFA), although state and local laws may be more restrictive.

    Another Space Force joke. FFS, have you kids got it out of your system yet?

  • AD AD on Jun 28, 2018

    I would love something like this that could feed from either the box magazine OR the tube. I don't know enough about the technical details to know how feasible something like that would actually be.

      @AD Not feasible, but a smart thought. I wouldn't want but I'd be more intrigued fo sho.
