Citadel Mariner 12 Gauge 18.50" 4+1 3" Pump-Action Shotgun - Black Synthetic Stock

The Citadel Mariner is a tactical pump-action shotgun chambered in 12 Gauge with a 3-inch chamber, built for hard use in wet, dirty, and rough environments. It pairs an 18.50-inch barrel with a full-length barrel heat shield and a 4+1 capacity, giving you the reach of a defensive shotgun in a compact, maneuverable package.

At the heart of the Mariner is a steel receiver topped with a Picatinny rail for mounting red dots or tactical sights, paired with a fixed black synthetic stock for weather resistance and durability. The pump-action cycles smoothly via the traditional forearm slide, and a side shell holder keeps spare 12 Gauge rounds staged on the receiver for fast reloads.

Target acquisition is handled by a blade front sight and an adjustable rear sight right out of the box, with the Picatinny rail ready to host an optic. The shotgun measures 39 inches overall and weighs 6.90 lbs, striking a balance between shootability and all-day handling. Three choke tubes are included so you can tailor the pattern to buckshot, slug, or bird loads.

Whether you need a capable tactical shotgun for home defense, a truck gun, or a rough-condition field gun, the Citadel Mariner delivers 12 Gauge performance in a no-nonsense package.
