Mossberg's 590 Shockwave Series are pint-sized but pack a serious punch. These pump-action firearms feature a 14.375" barrel and a unique "bird's head" grip that gives the weapon an overall length of 26.37" – making them perfectly legal to own without the need to fill out a Form 4 Application. The 590 Shockwave features a clean-out magazine tube for easy cleaning and maintenance. Like the other shotguns in the 500 family, the 590 Shockwave comes standard with a set of dual extractors, twin action bars, and an anti-jam elevator. Select models of the 590 Shockwave are available with additional features such as attractive wood furniture, perforated heat shields, detachable box magazines, laser sights, and unique foregrip options.
