One of the most talked-about firearms to come out of the 2017 SHOT Show was the Mossberg 590 Shockwave—a 12-gauge 14" barrel pump-action gun that does not require NFA paperwork. We've covered it extensively, and you can learn more about it here. One of the main questions folks have been asking since its introduction is, "Will it be offered in a 20-gauge model?" We now the answer: Yes, and they are already in production and shipping to wholesalers.

The 20-gauge version of the Shockwave required an engineering redesign, as this is Mossberg's first offering of the 590 in a smaller gauge. In addition to a scaled-down receiver, the cob-styled, tactical fore-end was reduced in overall size. The gun weighs in at a mere 4.95 lbs., has a 6-round capacity, and has an overall length of 26.4".

At the core of the 590 Shockwave is Mossberg's non-binding twin action bars, positive steel-to-steel lock-up, an anti-jam elevator, dual extractors and Mossberg's universally recognized, ambidextrous top-mounted safety. The lightweight receiver is constructed of anodized aluminum and is drilled and tapped for an optic or accessories. The magazine tube features a convenient clean-out cap. The gun is 2¾" and 3" capable and features a heavy-walled barrel with bead sight and matte blue finish. Rear and magazine cap sling swivel studs complete this compact package.

The "bird's head"-shaped pistol grip from Shockwave Technologies provides this 590 with its distinctive name. The Shockwave Raptor grip features an enhanced textured finish, allowing for maximum control while minimizing felt recoil. The grip is constructed of durable, glass-filled polymer with non-reflective, black finish and overall length of 5.25".

Specifications:
  • Type: 590 Non-NFA Pump-Action
  • Gauge/Chamber: 20-ga. 3"
  • Capacity: 6 shells
  • Barrel/Finish: 14.37" in Heavy-Walled Matte Blue
