Product Description

What's in the Box

  • Mossberg 590M Shockwave 12 Gauge Pump Action
  • (1) 10-Round Magazine
  • Cable Lock
  • Owner's Manual

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.

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. Additional features 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.

Although the Mossberg 590 Shockwave is classified as a “firearm” under GCA, and is not subject to the provisions of the National Firearms Act (NFA), state and local laws may be more restrictive. Although it is legal federally, the 590 Shockwave may be considered a “short-barreled” shotgun or “assault weapon” by certain state and local laws; and therefore illegal to possess. Please check with your local authorities concerning the legality of purchasing or possessing a firearm of this configuration.

(5 out of 5) NON-NFA Riot Control/Combat firearm
by from Kansas City, MO on

The drawbacks of traditional riot control and combat shotguns have accidentally been addressed by Mossberg- Bulky rotary and single stack mags have been replaced with a compact for 12ga double stack magazine that's built like it could be used as a weapon by itself. These magazines can be reloaded in seconds, meaning you can carry over 100 rounds of ready to fire 12ga ammo of your choice quite easily. 590 action guarantees smooth, reliable operation, and I can confirm 300 rounds cycled from different shooters without incident.
 Despite some initial fear of losing teeth trying to aim this, the recoil is very manageable with correct stance and grip- look up Hickock45s review on youtube for the regular shockwave to learn the correct way to shoot this gun with the bird head grip. If it's legal to own this firearm in your state, it's also probably legal to install a pistol brace in order to facilitate one handed shooting, and the installation of matching magpul furniture. This shotgun gets a lot of attention on the range, as anyone who has an interest in combat shotguns will naturally take note of this firearm. Also, blasting 20+ rounds of hot 12ga down range triggers a primal response in human beings causing them to involuntarily hoot and hollar like hillbillies.
