Introduction
The Benelli M4. The name alone conjures images of a robust, reliable, and undeniably effective shotgun. Revered by military, law enforcement, and civilian enthusiasts alike, the Benelli M4 is renowned for its gas-operated, semi-automatic action, its unwavering performance, and its ability to handle the harshest conditions. However, even perfection can be improved. One common modification sought by Benelli M4 owners is the addition of an extension tube for Benelli M4, seeking to enhance an already formidable platform. This article delves into the world of extension tubes, exploring their benefits, the legal landscape, different options available, and the critical considerations for proper installation and maintenance.
Adding an extension tube for Benelli M4 is more than just an aesthetic upgrade; it’s a practical enhancement that can significantly alter the capabilities of your firearm. The standard Benelli M4 typically boasts a magazine capacity that allows for a set number of rounds. An extension tube effectively increases the number of rounds your shotgun can hold, directly impacting several key aspects of its performance.
Benefits of Adding an Extension Tube
The most immediate benefit of an extension tube for Benelli M4 is, without a doubt, the increase in magazine capacity. With the standard capacity being a key feature, the ability to add more rounds translates into more rounds available for immediate use. This extended capacity is invaluable in various scenarios, from home defense to competitive shooting. Having more rounds on tap means fewer reloads, which can be a significant advantage in a high-pressure situation.
Beyond raw capacity, an extension tube for Benelli M4 can provide a tactical advantage. The speed at which you can engage multiple targets, or suppress a threat, is enhanced. The reduction in the need to reload in the midst of action is a distinct asset. This capability provides a clear edge in dynamic shooting situations, ensuring that you have the necessary firepower to meet a wide range of threats.
Another area often considered, though subjective, is the potential for improved balance and handling. While not a universal effect, the addition of an extension tube for Benelli M4 can, in some instances, slightly alter the weight distribution of the shotgun. If the added weight is well-placed, it may contribute to a more balanced feel, potentially improving the shooter’s swing and overall control. This is, of course, dependent on the length of the extension tube and the overall configuration of the firearm. It’s always important to assess how any modification feels in hand.
Legal and Regulatory Considerations
Before you rush to purchase an extension tube for Benelli M4, it is crucial to thoroughly understand the legal landscape. Federal, state, and local laws regarding magazine capacity are in place to regulate firearm ownership, and they vary widely depending on the jurisdiction. Some areas have strict limits on how many rounds a shotgun magazine can hold, while others are more permissive.
It is your responsibility, as a responsible gun owner, to research and understand the specific laws that apply to your location. Ignoring these regulations can lead to serious legal consequences, including fines, confiscation of your firearm, and even criminal charges. The rules regarding magazine capacity limits change frequently, so staying informed is key. Websites like the National Rifle Association (NRA) and local government resources can provide valuable information.
Types of Benelli M4 Extension Tubes
Choosing the right extension tube for Benelli M4 involves understanding the different types available. Several factors will guide your decision. The materials, length, and brand are all important considerations.
Materials
Extension tubes are primarily constructed from steel, titanium, or aluminum. Each material offers its own set of advantages. Steel, known for its durability and robust nature, is a reliable choice, providing good resistance to wear and tear. Titanium, in contrast, offers a significant advantage in terms of weight reduction while maintaining excellent strength. Aluminum is another popular choice, often favored for its lighter weight and resistance to corrosion. It is important to consider the material’s durability, weight, and resistance to environmental factors.
Length/Capacity Options
The length of the extension tube directly determines the increase in magazine capacity. Extension tubes are available in different lengths, each corresponding to a different number of additional rounds. This allows for customization, allowing you to tailor the capacity to your specific needs and legal requirements. The added length will, of course, affect the overall length and balance of the Benelli M4. Be mindful of the impact on the shotgun’s handling.
Brands and Manufacturers
A wide variety of companies manufacture extension tubes for Benelli M4. Well-regarded brands like Nordic Components and Briley are known for producing high-quality, reliable products. Doing your research is important. Look for a manufacturer with a strong reputation for quality and a track record of providing reliable products. Read reviews and compare features to find a brand that suits your needs.
Thread Pitch and Compatibility
Compatibility is critical. You absolutely must ensure that the extension tube for Benelli M4 you select is compatible with your specific model. The Benelli M4 uses a specific thread pitch, which is the measurement of the threads used to attach the extension tube to the magazine tube. If the thread pitch does not match, the extension tube will not properly attach, making the system unusable and potentially dangerous. Always verify compatibility before making a purchase. Check the manufacturer’s specifications and, if in doubt, consult with a gunsmith.
Installation Guide
Once you’ve chosen the right extension tube, the next step is installation. This process requires care and attention to detail. Remember to always handle firearms safely.
Before you begin, ensure the firearm is completely unloaded. Remove all ammunition from the shotgun and the surrounding area. Triple-check that the chamber is empty. Consider using a bore light to visually inspect the chamber.
Tools Required
Gather your tools: you will need a bench vise to securely hold the shotgun, a magazine tube wrench (or appropriate tools for removing the magazine tube), thread locker (like Loctite), a cleaning solvent, and appropriate wrenches. Safety glasses and gloves are also essential for protecting your eyes and hands.
Step-by-Step Instructions
The first step is to secure the Benelli M4 in a bench vise. Clamp the receiver securely but be careful not to overtighten, as this could damage the finish. The magazine tube will need to be removed. Often, the magazine cap needs to be unscrewed first. From there, the magazine tube can be removed. Often there is a specific tool required to remove the tube.
The next crucial step is installing the new magazine tube. Apply thread locker to the threads of the extension tube. This will help prevent it from coming loose during firing. Carefully thread the new extension tube onto the receiver. Tighten the tube to the manufacturer’s recommended torque specifications using the appropriate wrench. Do not overtighten.
Maintenance and Care
After installing the extension tube for Benelli M4, it is essential to perform a function check. This involves loading a few rounds into the magazine and cycling the action to ensure the ammunition feeds and ejects properly. Verify that there are no malfunctions. If any issues are encountered, carefully review the installation process and troubleshoot the problem.
Maintenance is crucial for ensuring the longevity and reliability of your extension tube for Benelli M4. Regular cleaning, inspection, and lubrication are essential for optimal performance.
Cleaning
Clean the extension tube regularly, particularly the threads. Use a cleaning solvent designed for firearms and a brush to remove any dirt, debris, or carbon buildup. After cleaning, wipe the tube down and allow it to dry completely.
Inspection
Regular inspection is a vital step. Carefully examine the extension tube for any signs of wear and tear. Look for any dents, scratches, or damage to the threads. Make sure that the extension tube is secure and there is no wobble. Should any issues be found, consider seeking help from a qualified gunsmith.
Lubrication
Proper lubrication is also important. After cleaning, lubricate the threads of the extension tube with a high-quality firearm lubricant. This helps prevent the threads from seizing and ensures smooth operation. Always follow the manufacturer’s recommendations for the type and amount of lubricant.
Safety Considerations
The addition of an extension tube for Benelli M4, while offering considerable benefits, requires awareness of safety practices. The modified firearm is a tool and should be handled with respect.
Always remember the four basic rules of gun safety: Treat every firearm as if it is loaded; never point the muzzle at anything you are not willing to destroy; keep your finger off the trigger until your sights are on the target; be sure of your target and what is beyond it.
After installing an extension tube for Benelli M4, and indeed after any modification, a function check is mandatory. This will verify that your shotgun cycles and ejects ammunition properly. Should any issues arise, consult a qualified gunsmith.
The addition of an extension tube for Benelli M4 offers more capacity, but it also changes the shotgun’s handling characteristics. Practice with the modified firearm is essential. Always practice safe gun handling.
Potential issues, though rare, can arise with an extension tube. Feeding problems may occur if the extension tube is not properly installed or if the magazine spring is not strong enough. If you experience feeding issues, check the installation, inspect the spring, and consider replacing it with a stronger one.
Conclusion
In conclusion, adding an extension tube for Benelli M4 is a worthwhile modification that can significantly enhance your shotgun’s capability. Increased capacity, improved tactical advantage, and potentially better balance are the main benefits. However, the addition of an extension tube for Benelli M4 demands careful consideration of legal requirements, the selection of the correct components, and precise installation. Remember to prioritize safety in every step. Thorough research and diligent attention to detail will ensure that your modification is safe and effective.
Adding an extension tube for Benelli M4 is a personal choice. Carefully evaluate your needs, familiarize yourself with local laws, and choose an extension tube that meets your requirements. Remember always to prioritize safety and responsible gun ownership. The Benelli M4, with or without an extension tube, is a powerful tool. Use it responsibly and always adhere to safety guidelines.
