Understanding Magazine Tube Extensions
What is a Magazine Tube Extension?
The Mossberg 500, a name synonymous with reliability and versatility, has earned its place as a cornerstone in the world of shotguns. From law enforcement to home defense, and the hunting fields, this pump-action firearm has proven its worth time and again. But even a classic can benefit from upgrades, and one of the most practical and impactful enhancements you can make is the installation of a magazine tube extension. This article dives deep into the world of these extensions, equipping you with the knowledge to transform your Mossberg 500 into an even more formidable and capable tool.
What exactly is a magazine tube extension? In simple terms, it’s an aftermarket accessory that increases the ammunition capacity of your Mossberg 500. This is achieved by replacing or adding to the existing magazine tube, allowing for more shells to be stored and readily available. These extensions are generally made of durable materials like steel or aluminum, and are designed to seamlessly integrate with the shotgun’s existing design.
Benefits of a Magazine Tube Extension
The benefits of adding a magazine tube extension are significant. First and foremost, it increases your shotgun’s firepower. More rounds on tap mean fewer reloads, giving you a tactical advantage in critical situations. This enhanced capacity is particularly valuable for home defense scenarios, where you want to have as much ammunition as possible readily available. It also benefits competitive shooting, where a few extra shells can make the difference between first place and a lower ranking.
Beyond sheer ammunition capacity, a magazine tube extension can also change the overall balance and handling characteristics of your Mossberg 500. Depending on the length and weight of the extension, you might find that the shotgun handles differently, perhaps feeling more front-heavy or providing a more natural pointing ability. This can lead to faster target acquisition and improved accuracy, especially in dynamic shooting environments.
Types of Magazine Tube Extensions
Various types of magazine tube extensions exist. They differ in terms of material, with steel and aluminum being the most common. Steel extensions are known for their ruggedness, while aluminum extensions often provide a balance of durability and weight savings. The increase in capacity also varies; extensions can add anywhere from a few extra rounds to a considerable number, often dependent on the overall length and the specific model of your Mossberg 500. Furthermore, some extensions come with additional features, such as a magazine tube clamp or a high-visibility follower, further enhancing the upgrade.
Choosing the Right Extension
Compatibility
Selecting the right magazine tube extension is crucial for optimizing your Mossberg 500. Compatibility is the first, and perhaps most important, consideration. The Mossberg 500 has been produced in various configurations over the years, and the extension must match your specific model. Ensure that the threading on the extension is compatible with the receiver of your shotgun. Check the barrel length of your shotgun to ensure the extension doesn’t exceed it. Some extensions are designed to be flush with the barrel, while others extend beyond.
Material and Finish
The material and finish of the extension contribute to both its longevity and its aesthetic appeal. Steel extensions generally offer superior durability, which is important if you plan on putting your shotgun through heavy use. Aluminum extensions are more lightweight, which can be beneficial for managing the overall weight of the shotgun, especially if you have other accessories mounted. The finish should match the color of your existing firearm. This will provide the best aesthetic result and avoid any unwanted variations.
Capacity
The capacity of the extension dictates how many additional rounds you can carry. Consider your intended use when making this decision. For home defense, a larger capacity can be advantageous. However, more capacity also means a heavier shotgun. So, you’ll want to balance the desire for more ammunition with the impact on handling and maneuverability. Always adhere to local laws and regulations regarding magazine capacity restrictions.
Brand Considerations
Choosing a reputable brand is paramount for ensuring you get a quality product that will perform reliably. Research different manufacturers and read reviews from other Mossberg 500 owners. Well-known brands often invest in quality materials, precision manufacturing, and rigorous testing, which translates to greater reliability and longevity.
Installation Guide
Tools and Materials Needed
Installing a magazine tube extension on your Mossberg 500 is a relatively straightforward process, but it’s essential to follow the steps carefully and prioritize safety.
Before you begin, gather the necessary tools and materials. You’ll need a wrench that fits the magazine tube cap, a vise (preferably with padded jaws to prevent scratching your shotgun), a thread locker (like Loctite), and safety glasses. Ensure that the firearm is completely unloaded. Double-check the chamber and magazine to verify the absence of any live ammunition.
Step-by-Step Installation Process
Begin by removing the original magazine tube cap. This typically involves unscrewing it from the receiver. You might need to apply some force, especially if it’s been on the gun for a long time. If the cap is difficult to remove, carefully secure the shotgun in a vise, taking care not to damage the finish.
Next, remove the magazine spring and follower from the original magazine tube. The spring is usually held under tension, so be careful when withdrawing it. Once removed, it’s wise to inspect the internal parts for excessive wear and tear.
Now, thread the new magazine tube extension onto the receiver. Make sure you align the threads carefully to avoid cross-threading, which could damage the receiver. If you’re using a clamp, install it at this stage to stabilize the connection.
With the extension properly threaded, it’s time to apply a small amount of thread locker to the threads. This helps to prevent the extension from loosening due to recoil or vibration. Then, tighten the extension firmly, using the wrench. Do not overtighten as this could damage your gun.
Finally, insert the new spring and follower. Ensure they move freely within the magazine tube. Once everything is in place, test the action of your Mossberg 500 by cycling a few dummy rounds. Verify that the gun feeds and ejects the rounds properly.
Troubleshooting Common Issues
If you experience any issues during the installation or after, consult online resources or a gunsmith.
Maintenance and Care
Cleaning
Proper maintenance ensures that your magazine tube extension functions reliably and extends the life of your Mossberg 500.
Cleaning should be performed periodically, especially after shooting. The frequency of cleaning will depend on how often you use your shotgun and the conditions in which it’s used. Remove the extension and clean the inside of the tube and the extension with a solvent designed for firearms. Remove any debris or carbon buildup.
Inspection
Regularly inspect the extension for any signs of wear and tear. Check the threads for damage, and inspect the magazine spring and follower for any signs of deformation or wear. The spring is critical for reliable feeding, and any weakening could lead to malfunctions. Replace any worn parts promptly.
Lubrication
Lubrication is also important. Use a quality gun oil or lubricant designed for firearms. Apply a thin film of oil to the inside of the magazine tube and to the follower. This reduces friction and helps the rounds feed smoothly. Avoid over-lubricating, as excessive oil can attract dirt and debris, potentially leading to malfunctions.
Legal Considerations
It is vital to be aware of all local, state, and federal laws and regulations regarding firearm ownership and modifications. Some jurisdictions have restrictions on the capacity of magazines. It’s your responsibility to know and abide by these laws. Contact local law enforcement or consult with a qualified legal expert if you have any questions or concerns about the legality of owning and modifying your shotgun in your area.
Conclusion
Adding a magazine tube extension to your Mossberg 500 is a significant upgrade that can greatly enhance its performance and versatility. By increasing your ammunition capacity, you gain a tactical advantage, improve your home defense capabilities, and potentially enhance your shooting experience. Remember to carefully choose the right extension, paying attention to compatibility, materials, and your personal needs. Follow the installation instructions meticulously, prioritize safety, and maintain your upgraded shotgun regularly.
By following this guide, you can confidently and safely upgrade your Mossberg 500 with a magazine tube extension, transforming it into a more formidable and reliable firearm. Now go out and enjoy the added capacity and performance.
