Description

The Citadel Mariner in matte black is one of those shotguns that just gets out of its own way and works. Chambered in 12 gauge with a 3" chamber, it runs a 4+1 capacity through a smooth-cycling pump action, and the whole package tips the scales right around 6.9 pounds with a 39-inch overall length. The 18.5" barrel, receiver, and furniture all wear a matte black finish, so there's a cohesive, business-like look to it instead of the nickel-and-walnut dress-up version.

What Sets This Mariner Apart

The full-length barrel heat shield is the detail everyone notices first. It gives the gun that classic tactical silhouette, but it also does a real job keeping your support hand off a hot barrel after a string of shells. Up top you'll find a Picatinny rail that opens the door for a red dot or other sighting setup, while the factory sights are a blade front paired with an adjustable rear so you can fine-tune your point of aim with buckshot or slugs. A side-mounted shell carrier keeps spare rounds right where you can reach them, and the swivel studs mean a sling is a quick add-on.

Choke Options on the Black Mariner

One thing worth calling out: this black model ships with five choke tubes, giving you more flexibility to tune your pattern for everything from tight slug and buckshot work to wider-spreading loads. Swapping tubes is simple, and it makes the Mariner surprisingly versatile for a gun built around home defense and truck-gun duty.

Who Reaches for a Mariner

Folks pick up the Mariner because it covers a lot of ground without a big outlay. It's light enough to handle quickly in tight quarters, the fixed synthetic stock shrugs off weather and hard use, and the 3" chamber lets you run heavier magnum loads when you want them. Whether it's riding in a closet for home protection or tagging along on the property, this is a straightforward workhorse that earns its keep.

Frequently Asked Questions

Is the Citadel Mariner optic ready?

The Mariner comes with a Picatinny rail mounted on top of the receiver, so you can add a red dot or other rail-mounted sight without any gunsmithing. It is not milled with a direct optic cut, but the rail gives you plenty of real estate for mounting. It ships with usable iron sights too, including a blade front and adjustable rear.

How many choke tubes come with the black Mariner?

This matte black FRMN1220BLK version includes five choke tubes, which is more than the nickel-finished Mariner models that ship with three. That gives you room to tune your pattern for buckshot, slugs, or spread-friendly loads. The tubes thread in and out easily for quick swaps.

What loads can the Citadel Mariner shoot?

The Mariner has a 3-inch chamber, so it handles both 2.75" and 3" 12 gauge shells. That lets you run everything from lighter target and defensive loads up to heavier 3-inch magnums. Its 4+1 capacity is based on 3-inch shells.

Does the Mariner have sling swivel studs?

Yes, this black Mariner comes with swivel studs installed, so adding a sling is a simple job with standard swivels. Combined with its roughly 6.9-pound weight and 18.5-inch barrel, it makes for an easy gun to carry and maneuver.
