## Understanding the Mossberg 590 Barrel Swap
### What is a Mossberg 590 Barrel Swap?
A Mossberg 590 barrel swap involves replacing the factory-installed barrel on your Mossberg 590 shotgun with a different barrel, often to change its length, choke system, or overall configuration. This modification can significantly impact the shotgun’s handling, accuracy, and suitability for various applications, such as home defense, hunting, or tactical shooting. The barrel swap process is generally straightforward, but it requires careful attention to detail and adherence to safety protocols.
### Why Consider a Barrel Swap?
There are several compelling reasons to consider a Mossberg 590 barrel swap:
* **Versatility:** Different barrel lengths and choke systems cater to specific shooting scenarios. A shorter barrel is ideal for close-quarters combat and home defense, while a longer barrel enhances accuracy at longer ranges for hunting.
* **Improved Accuracy:** Upgrading to a higher-quality barrel with a superior choke system can significantly improve your shotgun’s accuracy and pattern density.
* **Customization:** A barrel swap allows you to tailor your Mossberg 590 to your specific needs and preferences, creating a truly personalized firearm.
* **Repair or Replacement:** If your original barrel is damaged or worn, a barrel swap provides a cost-effective way to restore your shotgun’s functionality.
### Legal Considerations
Before performing a Mossberg 590 barrel swap, it’s essential to understand and comply with all applicable federal, state, and local laws. Pay close attention to minimum barrel length requirements for shotguns, as altering the barrel length may render your firearm illegal. Always consult with a qualified legal professional to ensure compliance with all relevant regulations.
## Choosing the Right Barrel for Your Mossberg 590
### Barrel Length
The barrel length is a critical factor to consider when selecting a replacement barrel for your Mossberg 590. Common barrel lengths range from 18.5 inches to 20 inches for home defense and tactical applications, and 24 inches to 28 inches for hunting and sporting purposes. Shorter barrels offer improved maneuverability in tight spaces, while longer barrels provide increased accuracy and range.
### Choke System
The choke system controls the spread of the shot as it exits the barrel. Different choke constrictions are suitable for various shooting scenarios. Common choke types include:
* **Cylinder Bore:** Provides no constriction, resulting in the widest shot pattern, ideal for close-range engagements.
* **Improved Cylinder:** Offers a slight constriction, providing a slightly tighter pattern than cylinder bore.
* **Modified:** Provides a moderate constriction, suitable for a wide range of applications.
* **Full:** Provides the tightest constriction, ideal for long-range shooting.
Some barrels feature fixed chokes, while others accept interchangeable choke tubes, allowing you to easily adjust the choke constriction to suit your needs.
### Barrel Material and Construction
The barrel material and construction significantly impact the barrel’s durability, accuracy, and overall performance. High-quality barrels are typically made from chrome-moly steel or stainless steel. Chrome-lined barrels offer enhanced corrosion resistance and ease of cleaning. Heavier barrel profiles can improve accuracy by reducing barrel flex.
### Compatibility
Ensure that the replacement barrel is specifically designed for the Mossberg 590. While some barrels may fit other Mossberg shotgun models, it’s crucial to verify compatibility to avoid potential safety hazards or malfunctions. Check the barrel’s thread pattern and receiver dimensions to ensure a proper fit.
## Step-by-Step Guide to Performing a Mossberg 590 Barrel Swap
### Safety First
Before beginning the barrel swap process, ensure that your Mossberg 590 is unloaded and the action is open. Double-check the chamber and magazine tube to confirm that no ammunition is present. Wear safety glasses to protect your eyes from debris.
### Tools and Materials
You will need the following tools and materials:
* Mossberg 590 shotgun
* Replacement barrel
* Wrench or socket set (if required for removing barrel nut)
* Soft-faced hammer (optional)
* Gun cleaning supplies
* Gun oil
### Disassembly
1. **Remove the Magazine Cap:** Unscrew the magazine cap at the end of the magazine tube.
2. **Remove the Barrel:** Depending on your model, you may need to loosen a barrel nut or retaining screw. Refer to your owner’s manual for specific instructions. Carefully slide the barrel forward and off the receiver.
### Installation
1. **Install the New Barrel:** Align the new barrel with the receiver and slide it into place. Ensure that the barrel is fully seated and properly aligned.
2. **Secure the Barrel:** Tighten the barrel nut or retaining screw to the manufacturer’s specified torque. Do not overtighten, as this could damage the receiver or barrel.
3. **Reinstall the Magazine Cap:** Screw the magazine cap back onto the magazine tube.
### Function Check
After completing the barrel swap, perform a function check to ensure that the shotgun operates correctly. Cycle the action several times to verify that the bolt locks properly and that the shells eject smoothly. **Important:** Never load live ammunition during a function check. Use dummy rounds or snap caps instead.
## Optimizing Performance After a Barrel Swap
### Headspace Adjustment
Headspace refers to the distance between the breech face and the cartridge when the action is closed. Improper headspace can lead to malfunctions or even dangerous conditions. It’s generally recommended to have a qualified gunsmith check the headspace after a barrel swap, especially if you are using a barrel from a different manufacturer.
### Pattern Testing
After installing a new barrel, it’s essential to pattern test your shotgun to determine the optimal choke constriction for your intended use. Shoot at a target at a known distance (e.g., 25 yards) and count the number of pellets that hit within a 30-inch circle. Adjust the choke constriction as needed to achieve the desired pattern density.
### Sight Adjustment
If your new barrel has different sights than your original barrel, you may need to adjust the sights to ensure accurate aiming. Use a bore sight or live fire to zero the sights at your desired range.
## Maintaining Your Mossberg 590 Barrel
### Cleaning
Regular cleaning is essential to maintain the performance and longevity of your Mossberg 590 barrel. After each shooting session, clean the barrel with a bore brush and solvent to remove fouling and residue. Dry the barrel thoroughly and apply a light coat of gun oil to prevent corrosion.
### Inspection
Periodically inspect your barrel for signs of damage, such as cracks, dents, or bulges. If you notice any damage, discontinue use immediately and consult with a qualified gunsmith.
### Storage
Store your Mossberg 590 in a dry, secure location to prevent corrosion and damage. Consider using a gun sock or case to protect the barrel from scratches and dings.
