Mossberg 590 Tactical 12 Gauge Pump Shotgun with Knoxx SpecOps Stock, Side-Saddle, Rails & Light
This customized Mossberg 590 Tactical pairs the proven reliability of the 12 gauge 590 action with practical upgrades focused on recoil control, ammo management, and accessory mounting. The Knoxx SpecOps recoil-reducing stock, Archangel top rail with seven-shell side-saddle, and forend Picatinny rail with clamp-mounted weapon light make this short, 18.5 inch cylinder-bore shotgun ready for duty or home-defense roles right out of the box.

What's Included
- Clamp-mounted tactical flashlight (installed on forend Picatinny rail)
- Archangel AA113 receiver-mounted Picatinny optics rail
- Archangel AA113 seven-shell side-saddle shell carrier
The Knoxx SpecOps adjustable stock features a collapsible buttstock, integral recoil-reducing mechanism, and textured pistol grip. Together, these elements moderate felt recoil while allowing shooters to set an optimal length of pull.
An Archangel AA113 aluminum Picatinny rail is secured to the top of the receiver. The rail provides a solid mounting platform for optics and incorporates a seven-shell side-saddle on the left side, keeping extra 12 gauge rounds immediately accessible.
The ribbed polymer forend carries an underside Picatinny rail. A clamp-mounted flashlight is already installed, giving the user a dedicated white-light source for low-light target identification without adding bulk.
The 18.5 inch steel barrel wears a fixed cylinder bore, accommodating both 2 3/4 inch and 3 inch shells. Mossberg’s twin-action-bar design, matte black anodized aluminum receiver, and top-tang safety maintain the rugged character that has made the 590 line a mil-spec standard.
From its recoil-reducing furniture to its integrated ammo and accessory management, this 590 Tactical offers a turnkey defensive package built around a battle-proven platform.
