Citadel Mariner 20G 18.5" Marine Finish Shotgun

The Citadel Mariner 20G 18.5" Marine Finish Shotgun is purpose-built for anglers, boaters, and coastal sportsmen who demand a reliable platform in saltwater environments. Designed specifically for the unique demands of marine use, this 20-gauge shotgun delivers the stopping power needed for waterfowl hunting, pest control, and personal protection without the excessive recoil of larger gauges. Whether you're working a marsh at dawn or securing your vessel, this firearm combines accessibility with serious capability—ideal for hunters and boaters who prioritize durability and ease of handling in demanding waterside conditions.

Built on the proven Howa platform, the Citadel Mariner features a corrosion-resistant marine finish engineered to withstand salt spray, humidity, and constant moisture exposure without degradation. The compact 18.5-inch barrel reduces weight and improves maneuverability in tight boat spaces and brushy cover, while the 20-gauge chambering provides sufficient shot energy for most waterfowl and game applications with lower recoil impulse—a critical advantage during long days on the water when fatigue impacts accuracy. The synthetic construction resists warping and moisture absorption, ensuring consistent cycling and reliability in conditions where wood stocks would fail within a season.

This shotgun is ideal for boaters, commercial fishermen, and serious waterfowl hunters who operate in saltwater or high-moisture environments where corrosion is an ongoing threat to equipment longevity. The 20-gauge platform appeals to shooters of smaller stature or those sensitive to recoil, making it accessible for family boating expeditions without sacrificing performance. Its compact dimensions allow secure mounting in boat lockers, cuddy cabins, or vehicle storage where full-length firearms create handling challenges. Pair the Citadel Mariner with marine-grade ammunition and a quality gun safe designed for moisture control to maximize service life in your offshore or coastal operation.
