Mossberg 590 Shockwave

The Mossberg 590 Shockwave is a uniquely classified 12-gauge pump-action firearm with a 14-inch barrel and a distinctive birds-head pistol grip that allows it to be legally sold as a non-NFA firearm under United States federal law. Because it is manufactured without a shoulder stock and has an overall length of 26.37 inches, the Shockwave falls into a regulatory category of 'firearm' rather than 'short-barreled shotgun,' making it accessible without the tax stamp and registration required for conventional short shotguns. The Raptor birds-head grip and forward strap provide positive control during one-handed and two-handed operation, and the Shockwave has become one of the best-selling firearms in its category for home defense and vehicle carry.
