What’s Included
- Mossberg 590 Shockwave 12 Gauge pump-action firearm
The Shockwave was the first commercially successful 14" barrel pump-action firearm to skirt NFA short-barreled shotgun classification, thanks to its 26.37" overall length and bird’s-head grip. Buyers get a compact platform without the added paperwork.
Its heavy-walled cylinder-bore barrel is built for longevity and copes well with both 2 3/4" and 3" shells. A brass bead front sight offers simple, snag-free aiming.
The aluminum receiver is drilled and tapped, allowing easy optics or accessory mounting. Mossberg’s proven tang-mounted safety remains ambidextrous and instinctive to reach.
A ribbed synthetic corn-cob forend with integral strap keeps the support hand secured and prevents over-travel during rapid cycling. The action is MIL-SPEC 3443 endurance qualified and accepts many Mossberg 500/590 components, giving owners ample customization options.
