REMINGTON MODEL 870 SPECIAL PURPOSE MARINE MAGNUM – 12 GA Pump-Action Shotgun

The Remington Model 870 Marine Magnum is a rugged, corrosion-resistant pump-action shotgun built for maritime operations, home defense, and tactical use in extreme environments. Based on the battle-proven 870 platform—one of the most widely used and trusted shotguns in the world—the Marine Magnum is designed to perform when reliability is non-negotiable.

What sets the Marine Magnum apart is its electroless nickel-plated finish on all metal components, including the barrel, receiver, and magazine tube. This coating provides excellent resistance to rust and corrosion, making it an ideal tool for humid, coastal, or saltwater conditions. Whether on a boat, in a patrol vehicle, or at home, it’s a shotgun that’s built to last.

Equipped with a synthetic stock and forend, a 6+1 capacity, and an 18½-inch cylinder bore barrel, the Marine Magnum is optimized for close-quarters engagements and defensive applications. The design includes a single bead front sight, twin action bars for smooth cycling, and sling swivel studs for ease of carry in the field.
