Mossberg 590 Shockwave 12 Gauge 3" 18.5" 6+1 Pump-Action Shotgun - Raptor Birdshead Grip

The Mossberg 590 Shockwave is a compact tactical pump-action built on Mossberg's legendary 590 platform, chambered in 12 Gauge with a 3" chamber that handles everything from light target loads to heavy buckshot and slugs. This 50639 configuration pairs an 18.5" heavy-walled barrel with a drilled and tapped matte blued stainless steel receiver, giving shooters a lightweight, maneuverable package that delivers the same time-tested 590 reliability in a uniquely compact format.

At the rear, the Shockwave wears Mossberg's signature black Raptor birdshead grip, which - combined with the heavy-walled barrel - keeps the gun balanced and naturally points from non-traditional shooting positions. Internally, it carries over the features that have made the 590 the choice of military and law enforcement worldwide, including the proven pump-action feeding system, an ambidextrous tang safety, dual extractors, and positive steel-to-steel lockup. The streamlined package strips away the conventional shoulder stock, leaving a fast-handling 12-gauge purpose-built for close-range defensive use, truck-gun duty, or recreational plinking.

This model feeds from an under-barrel tube for a total 6+1 capacity, wears a simple bead front sight for fast target acquisition, and ships with a fixed Cylinder choke for wide-pattern work at close quarters. The receiver is drilled and tapped to accept optics, red dots, or accessories, and the entire package tips the scales at just 5.50 lbs with an overall length of 30.75". Whether you're looking for a home-defense tool, a bedside companion, or a handy 12-gauge utility piece, the 590 Shockwave packs Mossberg dependability into one of the most distinctive 12-gauges on the market.
