The Citadel Mariner 12/18.5" Nickel/Walnut pump-action shotgun is purpose-built for home defense, sport shooting, and tactical applications where reliable close-quarters firepower is essential. This compact 12-gauge shotgun delivers the stopping power that law enforcement and military personnel have relied on for decades, packaged in a manageable 18.5-inch barrel profile ideal for confined spaces.
Built on a proven pump-action operating system, the Mariner cycles reliably across a wide range of ammunition types—from light target loads to heavy buckshot and slugs—without modification. The nickel-finished receiver resists corrosion and fingerprints, critical for weapons stored in vehicles or high-humidity environments, while the walnut furniture provides traditional aesthetics and proven durability in hard use.
The 12-gauge chamber accepts both 2.75-inch and 3-inch shells, offering versatility for various shooting scenarios. This shotgun excels for those prioritizing simplicity and raw effectiveness over modern ergonomic features—seasoned shooters who understand pump-action operation appreciate the straightforward controls and short learning curve. The compact 18.5-inch barrel makes it practical for vehicle storage, home defense corridors, and field use without sacrificing performance.
