What is the Remington 870 Marine Magnum?
A Distinctive Design for Marine Environments
The Remington 870. The name alone resonates with gun enthusiasts and those seeking a reliable, versatile shotgun. For decades, it has been a cornerstone in the world of firearms, earning a reputation for durability, simplicity, and a wide range of applications. Whether for home defense, hunting, or recreational shooting, the Remington 870 continues to be a favorite. But within the 870 family lies a specific variant designed for resilience against the elements: the Remington 870 Marine Magnum. And at the heart of this rugged shotgun is its barrel. This guide dives deep into the Remington 870 Marine Magnum barrel, exploring its features, performance, and what makes it a standout choice.
The Marine Magnum isn’t just another version of the iconic 870; it’s a purpose-built shotgun designed to withstand the harsh conditions of marine environments. This means it’s built to combat the corrosive effects of saltwater, humidity, and general wear and tear often encountered near or on the water. The distinctive feature is the comprehensive use of materials and finishes that provide superior resistance to rust and corrosion.
The “Marine Magnum” designation hints at its intended purpose. This firearm was conceived for those who work or spend time near bodies of water. It is an ideal choice for situations where exposure to moisture is a given. The primary goal is to maintain functionality and reliability even when exposed to potentially damaging conditions. This makes it a top option for boaters, law enforcement agencies, and anyone who appreciates a durable and reliable firearm.
A crucial aspect of the Marine Magnum’s corrosion resistance is its finish. Instead of the standard blued steel finish common on other 870 models, the Marine Magnum boasts a nickel-plated exterior. This treatment provides a robust barrier against moisture, preventing rust and extending the shotgun’s lifespan. This finish contributes not only to its durability but also gives it a distinct aesthetic. The lustrous nickel-plating is a visual indicator of the Marine Magnum’s special protection.
Key Characteristics of the Barrel: Materials and Construction
The Foundation of Durability
The barrel of the Remington 870 Marine Magnum is where its ruggedness truly shines. Let’s explore the specifics of what makes this barrel special.
A vital element is the material itself. The barrel is typically constructed from a high-quality steel alloy. This alloy provides the strength needed to withstand the pressures of firing various shotgun shells, including high-powered loads. It’s the foundation of a reliable, long-lasting barrel.
The magic, however, lies in the protective coating. The nickel-plating is not just a cosmetic touch; it’s a functional shield. It provides a barrier against corrosion that far surpasses that of blued steel, the standard finish on most 870 models. The nickel plating adheres tightly to the barrel’s surface, preventing moisture from reaching the underlying steel and initiating rust. This is essential for preserving the barrel’s integrity and ensuring that the shotgun remains functional, even in challenging conditions.
The nickel-plating also extends to the other metal components. This consistent application of corrosion-resistant treatment makes the Marine Magnum a comprehensive solution to the challenges of operating in demanding environments.
Exploring Different Barrel Lengths
Choosing the Right Fit
The Remington 870 Marine Magnum barrel comes in a range of lengths. The choice of barrel length impacts the shotgun’s handling characteristics and intended use.
Shorter barrels, often around 18 inches or less, are prized for their maneuverability. They are well-suited for close-quarters situations, such as home defense or tactical applications. The reduced length makes it easier to move the shotgun through tight spaces and quickly acquire a target.
Longer barrels, in the range of 26 to 28 inches, are better suited for hunting or sports shooting. Longer barrels tend to offer better accuracy and a higher muzzle velocity, which is particularly beneficial for reaching targets at greater distances. The downside of the longer barrel is the added weight and reduced maneuverability.
It’s essential to select a barrel length that matches your primary intended use. For home defense, the shorter barrel might be preferable. For hunting, the longer barrel may offer better performance.
Understanding Chokes
Controlling the Shot Pattern
Chokes play a crucial role in the performance of a shotgun. They regulate the spread of the shot pattern as it leaves the barrel, affecting the range and effectiveness of your shots.
Chokes are essentially tapered constrictions at the muzzle end of the barrel. They are designed to constrict or expand the shot pattern to meet the needs of the user. The Marine Magnum barrels often come with fixed chokes.
Fixed chokes are permanently attached to the barrel, meaning you can’t easily switch them out for different shooting scenarios. Common fixed choke configurations include improved cylinder, modified, and full. Improved cylinder chokes are typically open, spreading the shot pattern quickly for close-range targets. Modified chokes offer a tighter pattern, making them suitable for intermediate ranges. Full chokes deliver the tightest patterns, maximizing range.
The choice of choke impacts the effective range of your shots. A tighter choke increases the range, while a more open choke is better for close-range targets.
Sights and Rails on the Marine Magnum Barrel
Aiming with Precision
Sights are an essential component of any firearm, providing the user with the tools necessary to accurately aim. The Remington 870 Marine Magnum typically comes equipped with a bead sight.
A bead sight is a simple, effective aiming system consisting of a small bead located at the muzzle end of the barrel. It’s easy to use and quick to acquire, making it ideal for the close-range scenarios for which the Marine Magnum is often employed.
Aftermarket options exist. Users can often add aftermarket sights, and rails can be added as well, allowing the attachment of optics and other accessories. This kind of modularity makes the Marine Magnum a versatile tool.
Performance and Applications in the Real World
Putting the Marine Magnum to Work
The Remington 870 Marine Magnum barrel excels in a variety of applications. Its unique features make it particularly well-suited for certain situations.
One of the most common uses for the Marine Magnum is self-defense and home protection. The shotgun’s reliability, ease of use, and stopping power make it an excellent choice for defending yourself and your family. The corrosion-resistant construction ensures that the shotgun will function reliably, even if it is stored in a humid environment.
The Marine Magnum is also a popular choice for recreational shooting. Whether it’s trap shooting, skeet shooting, or just plinking at the range, the shotgun delivers a consistent and enjoyable shooting experience. Its reliability and the availability of different ammunition options make it versatile enough for various shooting sports.
If you plan to use the Marine Magnum in a marine environment, its corrosion resistance is particularly important. It is the ideal choice for boat owners or anyone who lives or works near the water. The added protection against saltwater and humidity ensures that the shotgun will remain in excellent working condition, no matter the conditions.
Ammunition Compatibility
Choosing the Right Loads
The Remington 870 Marine Magnum barrel is designed to handle a wide range of ammunition. The ability to use different shell types is a major part of what makes the shotgun so versatile.
The Marine Magnum, like the standard 870, accepts both 2 ¾-inch and 3-inch shells. The 3-inch shells are a popular option for hunting larger game, as they provide more power and range.
When selecting ammunition for the Marine Magnum, consider the intended use. For home defense, you might choose a shell loaded with buckshot, which offers a high degree of stopping power at close range. For hunting, you would likely choose a shell loaded with birdshot or slugs, depending on the game.
Accuracy and Range of the Shotgun
Hitting the Mark
Accuracy and effective range are vital considerations for any firearm. The Marine Magnum has its own performance profile.
Several factors affect accuracy, including the barrel length, the choke, and the shooter’s skill. The fixed chokes on the Marine Magnum can help to tighten the shot pattern, increasing accuracy.
The effective range of a shotgun depends on the load and the choke. With buckshot, the effective range is typically within 25-50 yards. With slugs, the range can extend to 100 yards or more.
Practicing regularly is essential for improving your accuracy. Familiarize yourself with the shotgun, and learn how to properly aim and handle it. Consistent practice builds muscle memory and helps you to achieve consistent results.
Upgrading and Replacing the Barrel
Customizing Your 870
Sometimes you might want to change the barrel on your Remington 870 Marine Magnum. Perhaps you want a different barrel length or choke configuration.
Make sure any replacement barrel is compatible. The Marine Magnum receiver is designed to accept specific barrels. Carefully check the specifications before purchasing a replacement.
The installation process involves removing the forend, unscrewing the magazine cap, and removing the barrel from the receiver. The new barrel is then installed, following the reverse steps. Always ensure the firearm is unloaded before performing any work.
