Mossberg 590M Shockwave 12-gauge Firearm
Mossberg introduces the 590M Shockwave 12-gauge firearm with 15-inch barrel, pistol grip and the world’s first double-stack, 10-round shotgun magazine. The Mossberg 590M combines the convenience and adaptability of a mag-fed shotgun with a “Non-NFA” pump-action platform. 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.
This Shockwave Technologies Raptor 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.
