Mossberg 590 Shockwave 20GA 14.5″ – 6 Round

Mossberg 590 Shockwave 20ga 14″ Compact Pump

When the diminutive size and potent 20 gauge power are required, turn to the Mossberg 590 Shockwave. This ultra-compact pump action packs the proven performance of the legendary 590 into a space-saving 26.37″ overall platform.

The 14.375″ heavy-walled cylinder bore barrel delivers optimum power and pattering for home defense applications. Despite the reduced dimensions, the Shockwave’s efficient design still allows for a 6-round capacity from the compact magazine tube.

The unique “bird’s head” grip and strap fore-end enable an extremely secure grip during operation in tight spaces. This model retains all the critical controls of the full-size 590, including Mossberg’s dual extractors, positive steel-to-steel lockup, self-adjusting twin action bars, and anti-jam elevator for absolute reliability.

The top tang safety is ambidextrous for intuitive manipulation by any shooter. The drilled and tapped receiver provides for easy optic mounting if desired. A cylinder bore choke comes installed from the factory.
