Introduction
The Remington 870 shotgun. The name itself conjures images of rugged reliability, versatility, and a legacy etched in the annals of American firearm history. For generations, the Model 870 has been a trusted companion for law enforcement, hunters, and home defenders alike. Its straightforward design, robust construction, and ease of use have cemented its status as one of the most popular shotguns ever produced. Among the many variants of the 870, the Super Mag stands out. Offering something more than its standard counterparts, the Super Mag is designed for the demands of higher performance.
At the heart of this shotgun lies the receiver – the foundational component that binds everything together. It’s the central nervous system, the structural backbone, and the critical element that allows the 870 to function flawlessly. This article delves deep into the Remington 870 Super Mag receiver, exploring its construction, its features, its role in the shotgun’s operation, and important considerations for maintenance and modification. We will unpack the intricacies of this core component, providing a comprehensive understanding for both seasoned enthusiasts and those new to the world of shotguns.
Understanding the Remington 870 Super Mag
The term “Super Mag” denotes a specific capability within the 870 family. It’s not just a marketing term; it signifies a significant design adaptation. The defining feature of the Remington 870 Super Mag is its ability to chamber and fire 3.5-inch 12-gauge shotgun shells. This extended shell length allows for a larger payload of shot, resulting in increased range and greater terminal effectiveness compared to standard 2.75-inch or 3-inch shells.
Distinguishing a Super Mag from a standard 870 is crucial. While the overall aesthetic might appear similar, subtle differences exist. These often manifest in the size of the ejection port, the chamber length, and the bolt. The Super Mag is built to accommodate the longer shell, and thus, requires specific components designed to manage the increased pressure and shell dimensions.
Several variants of the Super Mag have been produced, ranging from the rugged Express models, ideal for hard use, to the elegant Wingmaster iterations known for their polished finishes. Regardless of the specific model, the fundamental function remains consistent: to reliably cycle and fire 3.5-inch shells.
The benefits of choosing a Remington 870 Super Mag are manifold. The primary advantage is the increased power and reach provided by the larger shells. This is particularly advantageous for hunting waterfowl, turkey, or other game where longer shots are common. Furthermore, the versatility of the Super Mag allows the shooter to choose from a wide range of ammunition options, including high-powered magnum loads, offering a significant tactical advantage in certain situations. The Super Mag’s ability to accommodate a variety of shells makes it a flexible tool for diverse applications.
The Receiver: The Heart of the 870
The receiver is more than just a metal housing; it’s the very soul of the shotgun. It provides the structural integrity, houses the internal mechanisms, and facilitates the safe and efficient operation of the firearm. In essence, the receiver is the central processing unit.
Typically, the Remington 870 receiver is crafted from high-strength steel. Steel is chosen for its durability, its resistance to the extreme pressures generated during firing, and its ability to withstand the rigors of repeated use. The steel receiver also helps with longevity and resistance to damage. The receiver is often blued or coated to provide corrosion resistance and enhance its aesthetic appeal. The manufacturing process involves precision machining and rigorous quality control to ensure that each receiver meets stringent specifications.
Key features of the Super Mag receiver are unique and vital to its function. The chamber, designed to accommodate the 3.5-inch shell, is a defining characteristic. The bolt assembly interface, including the locking lugs, is meticulously engineered to withstand the increased forces generated by the larger shells. The barrel attachment is another critical aspect, ensuring a secure and accurate connection between the barrel and the receiver. Magazine tube attachment, which feeds the shells into the system, is another important design element specific to the Super Mag. The receiver also houses the safety mechanism and provides the interface for the trigger group. Each of these elements works harmoniously to enable the reliable function of the Super Mag.
Compatibility and Modifications
One of the great advantages of the Remington 870 is its adaptability, and this extends to the Super Mag variant. Understanding the compatibility of parts is essential for customization and maintenance.
Barrel selection is an important consideration. While the Super Mag receiver can accept barrels of varying lengths, it is critical to ensure that the barrel is specifically designed for the Super Mag chambering. Using a barrel meant for shorter shells can lead to malfunctions and potentially dangerous situations. Barrels are made specifically for the Super Mag, so it’s important to use the right ones.
Stock and fore-end compatibility is another area of interest for those looking to modify their shotgun. While many aftermarket stocks are designed to fit the standard 870 receiver, some may not be compatible with the Super Mag due to slight dimensional differences. Similarly, fore-ends might require specific modifications or be designed specifically for the Super Mag’s pump action. Always check product specifications.
The aftermarket offers a wide range of parts and accessories for the Remington 870 Super Mag, which can improve a shotgun’s performance. These include enhanced triggers, which provide a crisp and consistent pull; improved sights, for enhanced target acquisition; and tactical accessories such as shell carriers.
It’s crucial to remember that all modifications must adhere to local and federal firearm regulations. Safety should always be the top priority.
Maintenance and Care for the Receiver
Proper maintenance is critical to ensure the longevity and reliable function of the Remington 870 Super Mag. The receiver, like any other precision instrument, requires regular care.
Cleaning the receiver is a straightforward process that, if done regularly, will enhance longevity. It is advisable to use gun-cleaning solvents that are specifically designed for firearms. It’s essential to disassemble the shotgun partially, allowing access to all parts of the receiver. Brushes and cleaning rods can be used to remove carbon buildup and debris.
Lubrication is also a key element of maintenance. High-quality gun oils or lubricants should be applied sparingly to moving parts to minimize friction and prevent corrosion. The lubricant should be applied to the bolt, the action bars, and other key areas, ensuring a smooth cycling action.
Regular inspection is paramount. Before and after each shooting session, the receiver should be examined carefully for any signs of wear, damage, or excessive carbon buildup. Look for cracks in the steel, any unusual wear patterns on the bolt, or any looseness in the barrel attachment. Any observed issues should be addressed promptly.
Finally, proper storage is important. Store the shotgun in a dry, secure location, away from extreme temperatures and humidity. Consider using a gun safe or a gun case to protect it from damage and unauthorized access.
Common Issues and Troubleshooting
Even with diligent care, problems can occur. Recognizing and troubleshooting these issues is an essential skill for any 870 Super Mag owner.
Failure to feed is one such problem. It can be caused by a variety of factors, including a dirty chamber, a damaged magazine tube, or a worn extractor. Examine the chamber, clean it thoroughly, and inspect the magazine tube for any obstructions. Also, consider looking into the condition of the extractor.
Failure to eject is another common issue. This often results from a dirty extractor, a worn ejector, or a broken extractor spring. Inspect the extractor, clean it or replace any worn components.
Difficulties with shell length can also occur if the shotgun is not properly configured for the shell type. Make sure you are using the correct ammunition for the Super Mag.
When faced with these problems, follow a systematic troubleshooting approach. Start with a thorough cleaning and lubrication. Then, examine the components for any signs of wear or damage. If the issue persists, don’t hesitate to seek professional help from a qualified gunsmith.
