There's a reason marine-finish shotguns have a loyal following. Humid closets, boat lockers, salty air, and long stretches between cleanings are hard on blued steel, and the Citadel Mariner's nickel-finished barrel and aluminum receiver shrug all of that off. Legacy Sports International took the proven formula from its popular 12 gauge Mariner and scaled it down to 20 gauge, giving you noticeably lighter recoil in a gun that still hits plenty hard with modern buckshot and slug loads. At around 6.9 pounds with a 39 inch overall length, it swings quick and stores easy.
The 18.5 inch barrel wears a full-length heat shield and a 3 inch chamber that runs both 2.75 and 3 inch shells, feeding from a 4+1 tube. Sights are a step up from the usual bead: a blade front paired with an adjustable rear, plus a Picatinny rail on the receiver if you'd rather run a red dot. The controls follow the familiar 870 pattern, with the action release ahead of the trigger guard and a crossbolt safety, so anyone who's spent time behind an American pump gun will feel right at home. Twin action bars keep the pump stroke smooth and bind-free.
Three included choke tubes let this gun pull double duty. Screw in a tighter constriction and you've got a compact truck or camp gun that can handle small game and pests, or open it up for defensive patterns at household distances. The side shell holder keeps spare rounds on the gun where they belong, and the black synthetic stock with recoil pad handles bumps and weather without complaint.
For smaller-framed folks, new shotgunners, or anyone tired of getting beat up by 12 gauge loads, the 20 gauge Mariner is an easy gun to shoot well. Less recoil means faster follow-up shots and more enjoyable practice, and the weather-resistant finish means it's ready whenever you are.
Yes. Rifled (Foster-style) slugs run fine through this barrel, and the adjustable rear sight and blade front make it easier to zero for slug work than a plain bead gun. Just use one of the more open choke tubes, like improved cylinder, and avoid firing slugs through a full choke.
That's the whole point of the marine-style finish. The nickel-coated barrel and receiver are built to stand up to humidity, salt air, and sweat far better than traditional bluing. It's a smart pick for boats, coastal areas, or anywhere a gun might sit for a while between wipe-downs.
Yes, the receiver comes with an integrated Picatinny rail, so most micro red dots and compact optics will bolt right on with a standard mount. If you'd rather keep it simple, the factory adjustable rear and blade front sights work well on their own.
The 20 gauge delivers noticeably less recoil while still throwing an effective buckshot payload at household distances, and quality 20 gauge defensive loads keep getting better. It's easier for smaller-framed or recoil-sensitive users to control, which usually means faster and more accurate follow-up shots. Capacity, barrel length, and features are the same as its 12 gauge sibling.
