The Mossberg 590 is a legendary pump-action shotgun, prized for its reliability, versatility, and affordability. But one common modification among 590 owners is extending the magazine tube. This seemingly simple upgrade significantly impacts the shotgun's functionality, making it a more effective tool for various applications. This guide explores everything you need to know about Mossberg 590 tube extensions, helping you choose the right one for your needs.
Why Extend Your Mossberg 590's Magazine Tube?
Extending your Mossberg 590's magazine tube offers several key advantages:
-
Increased Capacity: The most obvious benefit is the increased ammunition capacity. This is crucial in home defense, hunting situations where multiple shots might be needed, or competitive shooting disciplines like 3-gun. More rounds mean less time spent reloading, giving you a tactical edge.
-
Enhanced Reliability: While the standard tube is reliable, a longer tube with better-quality components can further enhance reliability, especially in harsh conditions or with heavier loads.
-
Improved Ergonomics (Sometimes): Depending on the extension and your build, a longer tube can subtly improve the balance and feel of the shotgun. However, this is subjective and depends on individual preferences and the specific extension used.
Choosing the Right Mossberg 590 Tube Extension: Key Considerations
Selecting the right tube extension involves careful consideration of several factors:
1. Capacity:
The most crucial factor is the desired capacity increase. Extensions are available in various lengths, adding anywhere from a few to a dozen rounds, depending on your state's laws and your intended use. Always check local and federal regulations regarding magazine capacity before purchasing any extension.
2. Material and Construction:
Most extensions are made from steel or aluminum. Steel is generally more durable but heavier. Aluminum is lighter but may be less durable under extreme stress. Look for extensions with robust construction and a smooth, consistent finish. Poorly made extensions can lead to feeding problems or even damage to the shotgun.
3. Finish:
The finish of the extension is important for both aesthetics and corrosion resistance. Parkerized, Cerakote, or other durable finishes protect against rust and wear.
4. Compatibility:
Ensure the extension is specifically designed for your Mossberg 590 model (e.g., 590A1, 590 Shockwave). Some extensions might not fit all variants. Always check the manufacturer's specifications to ensure compatibility.
5. Installation:
Some extensions require professional installation, while others are designed for easy DIY installation with basic tools. Choose an option that aligns with your mechanical skills and comfort level.
Installation Tips (For DIY Installations):
While many extensions are easy to install, careful attention to detail is crucial. Always consult the manufacturer's instructions and:
- Clean your shotgun thoroughly before starting.
- Use the correct tools and proceed slowly and carefully.
- Ensure all components are correctly aligned before tightening.
- After installation, test fire your shotgun to verify proper function.
Potential Drawbacks of Tube Extensions:
-
Increased Weight: Longer tubes add weight to the front of the shotgun, which can affect handling, especially for extended periods.
-
Potential for Increased Recoil: While often minimal, a slightly increased recoil can be experienced with a heavier, extended magazine tube.
Conclusion:
A Mossberg 590 tube extension can be a valuable upgrade, enhancing the shotgun's capacity and functionality. However, careful selection and proper installation are crucial for ensuring optimal performance and safety. By considering the factors discussed above, you can choose the right extension to meet your specific needs and make your Mossberg 590 an even more effective tool. Remember always to check local and state laws before making any modifications to your firearm.
