Rem 870 Marine Magnum 12/18/3" Nkl

The Remington 870 Marine Magnum 12-gauge pump-action shotgun with 18-inch cylinder barrel and nickel finish delivers proven reliability in demanding saltwater and corrosive-environment applications. The nickel plating provides superior corrosion resistance compared to standard blued finishes, making this platform the choice for maritime law enforcement, coastal security operations, and offshore industrial roles where steel-on-steel exposure demands maximum durability.

Built on the legendary 870 platform, this Marine Magnum variant chambers the full 3-inch magnum round, enabling extended range and payload flexibility for tactical operations. The 18-inch barrel length balances maneuverability in confined spaces—critical for shipboard operations and vehicle interdiction—with sufficient sight radius for precision shot placement. The cylinder choke delivers predictable shot patterns across common duty distances. A 6-round magazine capacity paired with the synthetic stock ensures reliability without weight penalty in high-humidity environments where wood can warp or delaminate. The bead front sight provides rapid target acquisition under operational stress.

This configuration serves federal and state law enforcement agencies, military security personnel, private maritime security operators, and tactical training facilities requiring a shotgun rated for sustained saltwater exposure. The 870 platform's modular design supports professional-grade accessory mounting when mission requirements demand optics, lights, or breaching stands. Field-proven in thousands of deployments across decades, the 870 remains the standard pump-action reference in professional security and tactical environments.

The Remington 870 Marine Magnum 12/18/3" nickel-finish shotgun is a purpose-built tool for operators working in harsh marine and corrosive conditions where standard finishes fail. Its compact footprint, magnum capability, and proven reliability make it the go-to choice for professional maritime security and tactical operations.
