Understanding the Magazine Extension
What is a Magazine Extension?
The Mossberg 590 shotgun is a workhorse in the world of firearms, renowned for its reliability and versatility. From the battlefield to the backwoods, and increasingly in homes across the country, the 590 series has earned a reputation for being a dependable and powerful tool. For those seeking to further enhance their 590’s capabilities, a crucial upgrade to consider is the *Mossberg 590 Magazine Extension*. This guide will delve into everything you need to know about selecting, installing, and maintaining a magazine extension for your Mossberg 590, including the many benefits they offer.
A magazine extension is, in its simplest form, a device designed to increase the ammunition capacity of a shotgun’s magazine tube. It essentially extends the length of the magazine tube, providing more space for additional rounds. The core functionality of the extension involves holding more shells, which can significantly impact the overall effectiveness of your shotgun in various scenarios.
Why Use a Magazine Extension?
Why would you choose to utilize a *Mossberg 590 Magazine Extension*? The answer lies in the enhanced capabilities it unlocks. Primarily, it gives the user a significantly larger ammunition supply, which is an advantage in both defensive and competitive shooting situations. Having more rounds readily available can reduce the need for frequent reloads, providing you with more time to focus on your target. Consider a home-defense scenario; the extra rounds can offer peace of mind and increase your ability to manage multiple threats or extend the duration of a defensive encounter. In competition, the ability to load fewer times makes you faster and more competitive. While perhaps less crucial, some shooters appreciate the aesthetic appeal that a magazine extension adds to the overall look of their firearm.
Different Types of Magazine Extensions
Several types of magazine extensions are available. The most common style is the tube-style extension, which threads directly onto the existing magazine tube. Other options, though less common, might involve clamp-on designs. The choice of which type is best for your needs depends on factors such as the model of your 590, your budget, and your personal preference.
Compatibility and Key Considerations
Understanding Your 590 Model
Before rushing to purchase a *Mossberg 590 Magazine Extension*, it’s vital to understand your specific shotgun model and its compatibility requirements. The Mossberg 590 family consists of several models, each with its own characteristics. The standard Mossberg 590 is generally compatible with a wide range of extensions, while variants like the 590A1 often feature a heavier barrel and potentially different magazine tube lengths, which affect what extensions are suitable. The 590S, designed to handle shorter shells, may require a specific extension for optimal functionality. Thorough research and confirmation of compatibility for your exact shotgun model are paramount.
Measuring Your Magazine Tube
A critical step is measuring your existing magazine tube’s length. This measurement is absolutely essential when choosing an extension. The extension must be the correct length to ensure proper fit and function. An extension that is too short won’t add any capacity, and one that’s too long can interfere with other components or create an unbalanced feel.
Legal Considerations
Legal considerations also play a crucial role. Magazine capacity laws vary significantly by state and locality. Before purchasing or installing a *Mossberg 590 Magazine Extension*, be fully aware of your local laws and regulations concerning shotgun capacity. Some areas may impose restrictions on the maximum number of rounds a shotgun can hold. Ignoring these laws can lead to serious legal consequences. Ensure your chosen magazine extension complies with all applicable legal requirements.
Materials and Construction
The materials and construction of the extension impact both durability and the overall weight of your firearm. Steel extensions are known for their robust build and high durability, often making them a good choice for demanding applications. However, they can be heavier than extensions made from aluminum. Aluminum magazine extensions offer a good balance of strength and reduced weight, making them a popular choice for many shooters. The choice of material depends on your priorities; if weight is a primary concern, aluminum is likely better. If maximum durability is paramount, steel might be preferred.
Beyond the material, consider the overall build quality of the extension. Make sure the threads are cleanly cut and that the extension itself is free from defects. Finally, be aware that incorrect installation or the use of low-quality components can potentially impact the reliability of your shotgun. That’s why you should use a quality extension and follow all installation instructions precisely.
Choosing the Right Extension for Your Needs
Determining Capacity
Determining the desired capacity is the first step. How many extra rounds do you want to carry? Consider the initial magazine tube capacity of your 590. Most standard 590s come with a five- or six-round capacity. The goal is to add the desired number of rounds. For home defense, the added capacity provides more time to engage an attacker. In competitive shooting, the extra rounds can reduce the number of reloads required, leading to faster times.
Manufacturers and Brands
Several reputable manufacturers produce *Mossberg 590 Magazine Extensions*. Nordic Components, Choate, and Mesa Tactical are well-respected names in the industry. These companies typically offer extensions made from high-quality materials with robust construction. Researching the specific features and benefits of each manufacturer’s products will enable you to make an informed choice based on your needs and budget.
Extension Kit Components
A complete *Mossberg 590 Magazine Extension* kit typically includes several essential components. These include the magazine tube extension itself, a new spring designed to accommodate the increased capacity, and a follower. Some kits may also include a barrel clamp, which helps to secure the extension and prevent it from moving under recoil. It’s extremely important to ensure the new spring is the correct length and that the follower is smooth and properly functions. This will guarantee that rounds feed reliably.
Aesthetic Considerations
Aesthetics are also an area for consideration. Extensions come in a variety of finishes, from matte black to stainless steel or even cerakoted colors. Match the finish to your existing shotgun or choose a contrasting look for a custom appearance. Beyond the finish, you can often choose between different styles, such as fluted or smooth designs.
Installing Your Magazine Extension: A Step-by-Step Guide
Safety First
Before you begin the installation of your *Mossberg 590 Magazine Extension*, safety must be your paramount concern. Always ensure the shotgun is unloaded and that the chamber is clear. Verify that the magazine tube is empty, and follow all safety protocols. Work in a well-lit area, and keep ammunition away from your work area. Double-check your shotgun’s condition repeatedly throughout the process.
Tools Needed
You’ll need several basic tools for the installation. These generally include a wrench (often a dedicated magazine tube wrench or a suitable adjustable wrench), a screwdriver, a vise (optional, but helpful for holding the magazine tube during disassembly), and possibly a punch for removing any retaining pins. Gather all the necessary tools before you start, to avoid unnecessary interruptions.
Step-by-Step Instructions
Let’s break down the process of installing a *Mossberg 590 Magazine Extension* step-by-step:
- Disassembly: Remove the magazine cap (the threaded end cap on the magazine tube). This typically requires unscrewing the cap. Be prepared for the spring and follower to come out when you remove the cap, so control their release carefully. Carefully remove the spring and follower, and set them aside.
- Clean the Magazine Tube: With the cap, spring, and follower removed, inspect and clean the inside of the magazine tube. Remove any debris, oil, or grime that might interfere with the smooth operation of the extension.
- Attach the Extension: Carefully thread the *Mossberg 590 Magazine Extension* onto the original magazine tube. Use the proper wrench to tighten the extension securely. Don’t overtighten, as this can damage the threads, but make sure it’s snug. Torque the extension to the manufacturer’s recommended specifications, if any.
- Install the New Spring: Place the new spring (typically included with the extension kit) into the magazine tube. Ensure it is the correct length.
- Install the New Follower: Insert the new follower. It should slide smoothly inside the tube. If it binds at any point, recheck your work and the alignment.
- Install the Barrel Clamp (If Applicable): If your kit includes a barrel clamp, install it now, following the manufacturer’s instructions. The clamp helps to secure the extension and prevent any movement, especially under recoil.
- Function Check: Once the extension is fully assembled, perform a thorough function check. Load a few rounds into the magazine tube and cycle them through the action. Ensure the rounds feed smoothly, load correctly, and eject properly. If you experience any malfunctions, recheck the installation, make sure all components are properly aligned, and consult the manufacturer’s instructions.
By following these steps carefully, you can successfully install your *Mossberg 590 Magazine Extension* and reap the benefits of increased capacity and enhanced performance.
Maintenance and Troubleshooting
Cleaning Your Extension
Proper maintenance is crucial for ensuring the long-term reliability of your *Mossberg 590 Magazine Extension* and your shotgun. Regularly clean the magazine tube and extension to prevent the buildup of dirt, debris, and powder residue. Lubricate the magazine tube and spring lightly with a quality gun oil. This helps to ensure smooth operation and prevents corrosion. Inspect the magazine extension, spring, and follower for any signs of wear or damage.
Common Problems and Solutions
Even with proper maintenance, you might encounter some common problems. A failure to feed, where the shotgun fails to load the next round from the magazine, can often be caused by a weak or worn spring. The spring might not be providing enough force to push the rounds into the chamber. The follower itself can be damaged, preventing smooth operation. Examine the follower for wear and tear, and replace it if necessary.
Failure to eject is another common issue that might be related to your magazine extension. Make sure the shells are being fully pushed from the magazine into the chamber. Again, a damaged or malfunctioning spring could also lead to this problem. Inspect the extension for proper fit. Ensure there are no obstructions. Also, if you have the barrel clamp, make sure it is snug and hasn’t worked loose.
Jamming can also occur if the rounds are not loading properly. Again, review your work and make sure everything is properly aligned and fitted. If problems persist, consult the manufacturer’s instructions or seek professional help.
Real-World Applications and Important Considerations
Home Defense
The *Mossberg 590 Magazine Extension* enhances your shotgun in several real-world applications. In a home defense scenario, having extra rounds in your magazine allows you more time to react and manage a threat. More rounds can give you the advantage needed in a high-stress encounter.
Hunting Applications
For hunting applications, the increased capacity might be beneficial, depending on the specific regulations where you hunt. Some areas might have restrictions on the maximum magazine capacity for hunting.
Competition Shooting
Competitive shooting also offers the opportunity to use a *Mossberg 590 Magazine Extension*. Faster reloads and increased capacity often result in improved scores. This can give you a competitive edge.
Handling and Balance
When adding a magazine extension to your Mossberg 590, consider the changes in overall handling. The added weight, particularly when loaded, will shift the balance of the shotgun. Practice should address these changes. Consider the grip and how the shotgun feels when it’s fully loaded, so you are comfortable handling it under stress.
