The Citadel Mariner 12 gauge shotgun is a pump-action workhorse built for serious shooters who need reliable performance in a compact, manageable package. With an 18.5-inch barrel and 39-inch overall length, the Mariner handles like a rifle in tight spaces—perfect for home defense, tactical training, or hunting in brushy terrain where a shorter gun is an asset. Its synthetic furniture stands up to hard use and harsh conditions, while the nickel finish resists corrosion, making it a dependable choice whether you're running drills at the range or working in challenging environments.

Built on pump-action reliability that's proven across thousands of shotguns, the Mariner feeds 2¾- and 3-inch shells in its 4+1 capacity magazine tube—enough firepower for most jobs without excessive weight. Weighing 6.9 pounds, it balances quickly and points naturally. The gun ships with three interchangeable choke tubes, so you can tune your shot pattern for the distance and game you're hunting, or zero in on defensive performance at typical engagement ranges.

The Mariner comes configured for shooters who want to add optics and accessories: an adjustable rear sight mounted on a Picatinny rail lets you mount red dots, scopes, or backup irons, and a blade front sight keeps you running fast out of the box. A full-length barrel heat shield protects your support hand from burns during sustained fire or in the heat of the moment, and a side shell holder mounted on the receiver gives you quick access to spare rounds. All told, this is a no-nonsense platform that invites customization without forcing it.
