Changing the barrel on a Mossberg 590 shotgun is a relatively straightforward process, but it requires careful attention to detail and safety. This guide provides a comprehensive walkthrough, ensuring you can complete the task safely and effectively. Always prioritize safety when handling firearms. Before beginning, ensure the shotgun is unloaded, and visually inspect the chamber and magazine tube to confirm.
Tools You'll Need:
- A gunsmith's wrench: This specialized tool is crucial for properly tightening and loosening the barrel nut. Using the wrong tool can damage your firearm.
- Punch (optional): A brass punch can be helpful for tapping out the barrel nut if it's particularly stubborn.
- Protective eyewear: Always wear safety glasses to protect your eyes from flying debris.
- Gloves (optional): Gloves can help protect your hands and provide a better grip.
- New barrel: Obviously, you'll need a replacement barrel compatible with your Mossberg 590 model.
Step-by-Step Instructions:
1. Safety First: This cannot be stressed enough. Verify the firearm is unloaded. Point the muzzle in a safe direction.
2. Remove the Forend: Typically, this involves unscrewing or unclipping the forend, depending on your specific Mossberg 590 model. Consult your owner's manual if you are unsure.
3. Locate the Barrel Nut: The barrel nut is located at the receiver's end where the barrel meets the receiver. It's typically a large nut that secures the barrel to the receiver.
4. Loosen the Barrel Nut: Using the correct gunsmith's wrench, carefully loosen the barrel nut by turning it counter-clockwise. It may be quite tight, so apply firm but controlled pressure. A brass punch can assist if the nut is stuck.
5. Remove the Barrel: Once the barrel nut is loose, carefully pull the barrel forward and off the receiver. There may be some resistance, but it should come off relatively easily once the nut is removed.
6. Install the New Barrel: Align the new barrel with the receiver, ensuring it's properly seated.
7. Tighten the Barrel Nut: Using the gunsmith's wrench, carefully tighten the barrel nut by turning it clockwise. Do not overtighten. Too much force can damage the threads or the receiver.
8. Reattach the Forend: Securely reattach the forend, ensuring it's properly fastened.
9. Function Check: Before firing, perform a thorough function check to confirm the new barrel is properly installed and the shotgun functions correctly. Dry fire the weapon (with an empty chamber and magazine) several times to check for smooth operation.
Important Considerations:
- Barrel Compatibility: Ensure the new barrel is compatible with your specific Mossberg 590 model. Different models may have different barrel configurations. Check the manufacturer's specifications.
- Torque Specifications: While overtightening should be avoided, insufficient tightening can lead to barrel loosening and potential safety hazards. If you're unsure about the correct torque, consult a qualified gunsmith.
- Professional Assistance: If you are uncomfortable performing this task yourself, it's always best to seek the assistance of a qualified gunsmith. Improper installation can result in serious injury or damage to your firearm.
This detailed guide should enable you to successfully change your Mossberg 590 barrel. Remember that safety is paramount throughout this process. Always consult your owner's manual for specific instructions pertaining to your model.
