Mossberg made waves in the firearms industry when they announced the release of the 590 Shockwave; a 14-inch barrel 12-gauge that is not classified as an NFA firearm according to the BATFE (Bureau of Alcohol, Tobacco, Firearms & Explosives). They simply classify this compact 12-gauge a “firearm” so it can be acquired by any law-abiding citizen without the need for any tax stamps. This firearm features an extremely short barrel with a pistol grip, aptly named Raptors bird’s head because it looks like it has a beak. But it is not designed for looks, the handle is shaped that way to help mitigate the hand shock from the recoil of a 12-gauge shotgun shell. Even though it is extremely small, it still has all the features of the standard 590 series like twin action bars, dual extractors, anti-jam elevator, and positive steel-to-steel lockup which make this firearm extremely reliable. Whether you are looking for a home defense option or simply just a fun range gun, the Shockwave will fit the bill.

  • Extremely short 14” barrel
  • Classified as a firearm, no tax stamp required
  • Raptor bird’s head pistol grip made of polymer
  • Corn-cob style fore-end texture with hand strap for recoil mitigation
  • 6 round magazine tube capacity
  • Compatible with Mossberg 590 parts and accessories
  • Ambidextrous safety designed for low and no-light situations
  • Simple bead front sight
  • Dual extractors
  • Twin action bars
  • Anti-jam elevator
  • Positive steel-to-steel lockup
  • Removeable magazine cap for convenient cleaning
  • Heavy walled barrel

Because of its small size, the magazine tube can only hold six rounds but side saddle shell holders are available to make reloading faster. The synthetic corn-cob style fore-end is easy to pull back especially with the included hand strap that also helps to keep the muzzle down during recoil. Aiming isn’t the strong suit of this design but the bead front sight will definitely help for quick aiming in small hallways, which is where the Shockwave excels. Perfect for hiding under your bed, you will be able to quickly access this gun in the middle of the night and the ambidextrous safety is easy to locate and activate when in the dark. The magazine tube also features a removeable cap to make cleaning quick and easy.

Since 1919, Mossberg has been the leader in introducing important design advances to the firearms industry. Through design and an innovative edge, Mossberg is truly changing the way shooters use shotguns and rifles. Mossberg brings reliable, well-built shooting systems to you at an affordable price.
