Marine-finish shotguns have been a staple for boat owners, campers, and anyone who stores a gun somewhere damp, and the Citadel Mariner brings that concept to the 20 gauge crowd. The nickel finish covers the 18.5-inch barrel and the aluminum receiver, standing up to humidity and salt air far better than a standard blued gun. Legacy Sports paired that weatherproof metalwork with a fixed walnut stock, so the whole package has a classic look that stands out in a sea of black polymer.
A 20 gauge in a defensive pump gun is a smart move for a lot of people. You get noticeably less recoil than a 12 gauge, which means faster follow-up shots and a gun the whole household can run comfortably, and modern 20 gauge buckshot loads still carry plenty of payload for the job. The 3-inch chamber digests both 2.75 and 3-inch shells, and the 4+1 capacity keeps you topped off with a side shell holder right there on the receiver when you need more.
If you have ever run an 870, you will feel right at home here. The action release sits in front of the trigger guard, the crossbolt safety lives behind the trigger, and twin action bars keep the pump stroke smooth and bind-free. Up top, an adjustable rear sight rides on a Picatinny rail, so you can dial in your point of impact with slugs or swap on a red dot without any gunsmithing. A fiber optic front sight picks up light nicely in dim conditions.
The included choke tubes are the sleeper feature on this gun. Most 18.5-inch defensive shotguns come with a fixed cylinder bore, but the Mariner lets you tighten up patterns for small game, pests around the property, or just experimenting at the range. At 6.9 pounds and 39 inches overall, it is compact enough for tight hallways and light enough to carry all day. This is a versatile, weather-resistant pump gun that pulls double duty without complaint.
Yes. The Mariner has a 3-inch chamber, so it runs both 2.75-inch and 3-inch 20 gauge shells. That gives you the full range of options from light target loads up to magnum buckshot and slugs.
It does, which is unusual for an 18.5-inch defensive shotgun. Three choke tubes are included, letting you tighten or open up your patterns depending on the load and the task. That flexibility makes it far more versatile than a fixed cylinder bore gun.
Very much so. The Mariner uses an 870-style layout with the action release lever in front of the trigger guard and a crossbolt safety behind the trigger. It also runs on twin action bars for a smooth, reliable pump stroke, so anyone familiar with an 870 will adapt in seconds.
Yes. The receiver comes with a Picatinny rail on top, so mounting a red dot or other compact optic is straightforward. If you prefer irons, the adjustable rear sight and fiber optic front work well right out of the box.
