The Mossberg 590 Mariner delivers uncompromising reliability in marine environments where corrosion destroys standard shotguns. This 12-gauge pump-action features Marinecote finish protection and versatile configuration options for tactical applications.
What Makes This Different
The proprietary Marinecote finish provides superior corrosion resistance compared to standard blued or parkerized shotguns. This electroless nickel coating withstands saltwater exposure, humidity, and harsh weather conditions that would pit and rust conventional finishes. The cylinder bore barrel accepts rifled slugs and buckshot equally well, while the included pistol grip conversion kit allows rapid field reconfiguration from standard stock to compact tactical setup.Key Features
