The Foundation of Reliability: Function and Anatomy of the Magazine Tube
The Tube Itself
The foundation of the system is the tube, typically constructed from high-quality steel, though sometimes aluminum is used. Its robust construction ensures it can withstand the rigors of repeated use and potential impacts. The length of the tube dictates the number of shells it can hold, directly influencing the shotgun’s capacity. The material choice, whether steel or aluminum, plays a role in durability and weight, with steel tubes known for their exceptional strength.
The Internal Mechanism: The Magazine Spring
Tucked inside the tube is the magazine spring, a coiled marvel of spring steel. This spring exerts constant pressure on the shells, pushing them towards the bolt and ensuring reliable feeding. The spring’s strength and quality are paramount; a weak or worn spring can lead to feeding failures, hindering the shotgun’s performance.
The Guiding Light: The Magazine Follower
Located at the forward end of the spring, the magazine follower is a small, but vital piece. This brightly colored component, often made from polymer or metal, sits on top of the spring and slides against the inner wall of the magazine tube. Its role is twofold: to provide a smooth surface for the shells to slide against, and to alert the user when the magazine is empty, as it engages the bolt catch. The follower’s smooth surface and proper function are critical for reliable operation.
Securing the Load: The Magazine Cap
The magazine cap is the front-most component of the system. It screws onto the end of the magazine tube, securing the spring, follower, and shells within. The cap must be securely fastened to prevent accidental disassembly and to maintain proper spring pressure.
The interaction between these elements is a beautiful example of mechanical simplicity. When the action is cycled, the bolt extracts a spent shell and ejects it. Simultaneously, the lifter rises, presenting a fresh shell from the magazine tube. The bolt pushes the shell into the chamber, and the cycle continues until the magazine is empty or the action is locked open. The Remington 870 magazine tube and its components work in perfect harmony with the other parts of the shotgun, making for a reliable system.
Expanding Options: Types and Variations of the Remington 870 Magazine Tubes
Standard Choices: Factory Lengths and Capacities
The standard Remington 870 magazine tube comes in a few factory lengths, designed to accommodate different shell capacities. The most common configurations include a tube that holds four, five, or seven rounds (plus one in the chamber). These factory lengths are a balance of capacity, balance, and compliance with any applicable laws. When selecting a shotgun, consider your intended use, and whether capacity is important for your needs.
Boosting Capacity: Extended Magazine Tubes
For those seeking increased firepower, extended magazine tubes are a popular modification. These tubes are longer than standard and increase the number of rounds the shotgun can hold. They are typically available in a range of sizes, offering a significant boost in capacity. However, installing an extended tube may require additional components, such as a barrel clamp, to secure the tube to the barrel.
Material Matters: Choices in Construction
While the primary function remains the same, the materials used in the construction of magazine tubes can differ. Steel tubes offer maximum durability and are resistant to wear and tear. They can handle a great amount of abuse. Aluminum magazine tubes are another option, offering weight savings. Both types have benefits.
Maintaining Performance: The Importance of Care and Troubleshooting
A Clean Machine: Maintaining the Magazine Tube
Cleaning the magazine tube should be part of the regular maintenance routine. The frequency of cleaning will depend on the use of the shotgun. However, it’s a good practice to clean it every few hundred rounds fired or after any exposure to harsh conditions. Disassembly involves removing the magazine cap and spring. Use a suitable solvent and a cleaning rod to wipe away any dirt, debris, or residue from the interior of the tube. Then, ensure that the spring, follower, and interior are lubricated with a light coat of gun oil.
Addressing Issues: Common Problems and Solutions
Even with proper maintenance, issues may arise. Familiarity with common problems and their solutions can save valuable time and frustration. One of the most frequent problems is a failure to feed. Often, this is related to a worn or damaged magazine spring. Replacing the spring is a straightforward fix. Similarly, a damaged or poorly maintained magazine follower can cause feeding problems. Inspect the follower for wear and tear, and replace it as needed. Corrosion and rust can also occur, especially if the firearm is stored improperly. If corrosion is present, it must be removed to prevent further damage. Cleaning is essential, and can often prevent problems.
Matching the Right Tools: The Importance of Shell Compatibility
Always use ammunition that is designed for your Remington 870 magazine tube. This means ensuring the shell length is compatible with the magazine’s capacity. Using improper ammunition can lead to feeding issues and even damage to the firearm. Check the manufacturer’s recommendations to make sure the rounds work well with your shotgun.
Elevating Performance: Upgrades and Modifications
Boosting Reliability: Enhancing the Magazine Spring
Upgrading the magazine spring is one of the simplest and most effective improvements. A stronger spring ensures reliable feeding, especially when using heavier loads or when the firearm has seen a lot of use. There are many brands of springs to consider.
Improving Visibility and Feeding: Enhancing the Magazine Follower
Replacing the original magazine follower with a high-visibility, enhanced follower can improve both reliability and ease of loading. The polymer or metal followers are often brightly colored, making it easy to see when the magazine is empty. The follower’s material is also designed to be impact-resistant.
Adding Security: Additional Accessories for the Magazine Tube
A barrel clamp can be added to the barrel and magazine tube to add stability and prevent damage to the magazine tube during recoil. Clamps are available in a variety of styles and mounting options.
Setting It Up Right: Installation and Safety Measures
Preparedness: Safe Disassembly and Assembly
Begin by ensuring the shotgun is completely unloaded and that the chamber is clear. Properly disassemble the magazine tube by removing the magazine cap, then carefully extracting the spring and follower. When assembling, ensure that all components are correctly aligned and that the magazine cap is securely tightened. Always follow the manufacturer’s instructions for disassembly and reassembly.
Proper Tools: Required Tools and Equipment
Ensure you have the necessary tools, including a suitable wrench or screwdriver for removing the magazine cap and cleaning tools.
Safety First: Safety Considerations
Always wear eye protection. Avoid pointing the muzzle of the shotgun in any direction you are not willing to destroy. Familiarize yourself with all safety regulations, and keep your firearm secure.
Following the Law: Legal Considerations
Understand local, state, and federal laws regarding magazine capacity and modifications. Some jurisdictions may restrict the number of rounds a shotgun can hold or the types of modifications that are permissible. Always comply with the law.
The Long Game: Conclusion
The Remington 870 magazine tube is more than just a container for ammunition. It is a vital component that significantly affects the performance and reliability of the shotgun. By understanding the mechanics, the types, maintenance, and potential upgrades, owners can ensure their Remington 870 functions flawlessly for years to come. Taking care of the Remington 870 magazine tube is an investment in the long-term reliability and performance of the shotgun.
When you take care of your Remington 870 magazine tube, it will take care of you.
