Mossberg 590 Shockwave Tactical Defense 12 Gauge Woodland 14.375" 50634

The 590 Shockwave Nightstick is a compact pump-action shotgun built on Mossberg’s proven 590 platform. Shockwave models feature a 14.375 in heavy-walled barrel, an anodized aluminum receiver that is drilled and tapped, a single bead sight and a cylinder-bore barrel. The platform uses non-binding twin action bars, positive steel-to-steel lock-up, an anti-jam elevator and dual extractors for reliable operation. The Nightstick variant gives the Shockwave a retro look with a bird’s-head style grip and a strapped corn-cob forend; the leather forend strap is stamped with the Mossberg logo. The Shockwave line is described by the manufacturer as compact personal-defense firearms with an overall length designed to meet non-NFA requirements while remaining suitable for close-quarters use and field/boating environments.
