Description
The Remington 870 Marine 12 Gaa 18″ Barrel Nickel Coating 6rd is a corrosion-resistant, 12-gauge pump-action shotgun built on the legendary 870 platform. It features a nickel-plated metal finish and synthetic stock for harsh environments, an 18-inch cylinder bore barrel, and a 6-round capacity. This model is designed for durability and reliability where moisture and salt are concerns, offering a proven design with enhanced protective finishes. It’s a practical, no-frills workhorse for specific defensive and marine applications.
Key Features
- Nickel-Plated Defense: The entire metal surface—receiver, barrel, and trigger assembly—gets a protective nickel electroplating. This fights rust from humidity, salt spray, and fingerprints far better than standard bluing.
- Marine-Tough Furniture: The synthetic stock and forend won’t swell, warp, or rot when wet. It’s also impervious to most solvents used for cleaning.
- 18″ Cylinder Bore Barrel: The short barrel keeps the shotgun maneuverable in tight quarters. The cylinder bore (no choke) is optimized for defensive loads and buckshot patterns at close range.
- 6-Round Capacity: Holds 5 in the tubular magazine plus 1 in the chamber. That’s one more than many standard 870 Express models, giving you a slight edge before reloading.
- Proven 870 Action: You’re buying one of the most dependable pump-action mechanisms ever made. It’s simple, rugged, and has a massive aftermarket for parts and accessories.

Here’s the thing—while the nickel finish adds cost, it eliminates the need for aftermarket coatings like Cerakote on a standard 870, which can run $200-$300. At $723.79, you’re getting a factory-finished package that’s ready for harsh conditions right out of the gate. The weight, a solid 7.5 pounds, helps manage 12-gauge recoil, making follow-up shots more controllable. This model is drop-in ready for a wide range of standard 870 accessories, including stocks from Magpul or forends from SureFire, giving you customization paths without gunsmithing.
Who This Shotgun Is For
This isn’t a general-purpose hunting gun. It’s a specialist. The primary buyer is someone who needs a reliable firearm for a damp environment—think boat owners, coastal residents, or anyone living in the humid Midwest. It’s also a solid choice for a home defense shotgun that can be stored long-term in a basement safe or closet without constant worry about surface rust. If your priority is a low-maintenance, grab-and-go pump action that you might not baby, this 870 Marine makes a compelling case.
Practical Pros & Cons
Pros: The corrosion resistance is the main event, offering real peace of mind. The 870’s reputation for reliability is unmatched. The 6-round capacity is a practical upgrade. The synthetic furniture is durable and low-maintenance. And the design is compatible with a huge array of aftermarket parts for the Remington 870 platform.
Cons: The nickel finish can show scratches more than matte finishes, and it has a distinctive bright look that isn’t for everyone seeking a tactical aesthetic. The price point is higher than a basic 870 Express. That said, you’re paying for the specialized finish—it’s a tradeoff between initial cost and long-term protection.
Frequently Asked Questions
Q: Is the nickel plating just on the outside?
A: No, the electroplating process covers all metal parts, internal and external. This includes the bolt, shell lifter, and inside the receiver, providing corrosion protection throughout the action.
Q: Can I shoot slugs accurately through the cylinder bore barrel?
A: Yes, but with limitations. Cylinder bore barrels are acceptable for rifled slugs at shorter defensive ranges (inside 50 yards). For dedicated, precise slug shooting at longer distances, a rifle-sighted barrel with a choke would be a better choice. The 18-inch barrel is really meant for close-quarters.
Q: How does this compare to a Mossberg 590 Mariner?
A: They’re direct competitors. The Mossberg uses a different action (tang safety, dual extractors) and has an aluminum receiver, making it slightly lighter. The 870 Marine has a steel receiver and a arguably smoother, more traditional pump stroke. Both have excellent anti-corrosion treatments. It often comes down to personal preference for the control layout—try handling both if you can.
This Remington 870 Marine represents a specific value proposition: pay more upfront for a finish that saves you maintenance hassle and worry down the line. It’s a tool built for a job, not a range toy. If your environment demands it, the investment makes sense.
