Can I Change the Barrel on a Mossberg 590? A Comprehensive Guide
The Mossberg 590 shotgun is a highly popular and versatile platform, prized for its reliability and adaptability. One common question among owners is the feasibility of changing the barrel. The short answer is: yes, you can change the barrel on a Mossberg 590, but it's crucial to understand the nuances involved to ensure a safe and successful process.
Understanding Mossberg 590 Barrel Interchangeability
The beauty of the Mossberg 590 lies in its modular design. The barrel is easily detachable, allowing for customization based on your shooting needs. However, not all barrels are created equal. While various aftermarket and factory barrels are available, compatibility is paramount.
Key Considerations for Barrel Swapping:
- Gauge: Ensure the new barrel matches the gauge of your receiver. A 12-gauge barrel will not fit a 20-gauge receiver, and attempting to force it could result in serious damage.
- Length: Barrel lengths vary significantly, impacting the overall length of the firearm and its handling characteristics. Check your local and state regulations regarding minimum barrel lengths.
- Thread Pattern: While Mossberg generally maintains consistency, it's essential to verify that the new barrel's threads precisely match your receiver's threads. An improper fit can lead to dangerous consequences.
- Manufacturer: Stick to reputable manufacturers of Mossberg 590 barrels. Using low-quality or incompatible barrels can compromise the firearm's safety and reliability.
The Process of Changing a Mossberg 590 Barrel (General Steps)
Disclaimer: Always prioritize safety. If you are uncomfortable with any part of this process, seek assistance from a qualified gunsmith. Improper handling of firearms can lead to serious injury or death.
These steps are general guidelines; consult your firearm's manual for specific instructions and safety precautions.
- Unloading the Shotgun: This is the most crucial step. Completely unload the shotgun, ensuring the chamber and magazine tube are empty. Visually inspect to confirm.
- Removing the Existing Barrel: Depending on your 590 model, you might need to remove the forend. Then, locate the barrel nut and use the appropriate wrench (often a wrench specifically designed for Mossberg shotguns) to unscrew the nut. Once the nut is loosened, the barrel should slide off.
- Installing the New Barrel: Carefully align the new barrel with the receiver, ensuring proper engagement. Screw the barrel nut back on by hand, then tighten it securely using the wrench. Do not overtighten.
- Reattaching the Forend (if removed): Reinstall the forend, ensuring it’s properly secured.
- Final Inspection and Function Check: Before using the shotgun, thoroughly inspect the new barrel installation. Make sure the barrel is securely attached and functioning correctly. A dry fire (without live ammunition) can help check the action.
Choosing the Right Barrel for Your Mossberg 590
The choice of barrel depends on intended use. Popular options include:
- Shorter Barrels (e.g., 18.5 inches): Ideal for home defense, offering maneuverability in close quarters.
- Longer Barrels (e.g., 20-28 inches): Better suited for hunting or longer-range shooting, providing improved accuracy and reduced recoil.
- Specialized Barrels: Consider barrels designed for specific purposes, such as bird hunting or slug shooting. These often feature specialized chokes.
