Why Disassemble Your Mossberg 500?

Routine maintenance is crucial for keeping your Mossberg 500 in excellent working condition. Disassembling your shotgun allows you to clean all the critical components, check for wear, and ensure that everything is functioning smoothly. Regular disassembly also helps prevent malfunctions, improves performance, and prolongs the lifespan of your firearm.

In addition to regular cleaning, disassembling your Mossberg 500 might be required if you’re troubleshooting a malfunction, upgrading parts, or preparing the shotgun for storage. With that said, let’s dive into the process of disassembling the Mossberg 500 shotgun.

Step-by-Step Guide to Disassembling Your Mossberg 500

Before you begin, ensure that your Mossberg 500 is unloaded. Always double-check that the chamber is clear and that there are no rounds in the magazine tube. Safety first!

Step 1: Remove the Barrel

Start by ensuring that the shotgun is unloaded and the safety is engaged. Next, follow these instructions:

• Locate the magazine cap at the front of the shotgun.
• Unscrew the magazine cap by turning it counterclockwise. This will release the barrel from the receiver.
• Once the cap is removed, gently slide the barrel off the magazine tube and away from the receiver. Set the barrel aside in a safe location.

Step 2: Remove the Forend

With the barrel removed, the next step is to take off the forend (the handguard that covers the magazine tube and action). Here’s how to do it:

• Place your Mossberg 500 shotgun on a stable surface with the receiver facing up.
• Locate the forend retention screw at the front of the receiver.
• Using a flathead screwdriver, unscrew the retention screw until it is completely detached.
• Once the screw is removed, gently pull the forend off the action tube. Set it aside carefully.

Step 3: Remove the Trigger Group

The trigger group is an essential part of the Mossberg 500 and needs to be removed for further disassembly. Follow these steps:

• Look for the trigger group pin on the bottom of the receiver.
• Using a punch or small tool, tap the pin out gently.
• Once the pin is removed, the trigger group should come loose. Carefully lift it out of the receiver.

Step 4: Remove the Action Bar Assembly

Next, it’s time to remove the action bar assembly. Here’s how to do it:

• Pull the action bar back slightly so you can access the action bar lock.
• Press the action bar lock inward and continue to pull the action bars forward, removing them from the receiver.
• Set the action bar assembly aside.

Step 5: Remove the Bolt and Bolt Carrier

The bolt is a critical component of your Mossberg 500 and must be removed for a thorough cleaning. To remove the bolt and bolt carrier:

• Pull the action bars all the way back, exposing the bolt carrier group.
• Lift the bolt carrier group upward and out of the receiver.
• Once removed, inspect the bolt, firing pin, and extractor for any signs of wear or damage.

Step 6: Final Check

At this point, you’ve disassembled most of the major components of your Mossberg 500. It’s now time to check each part for signs of wear, corrosion, or damage. If necessary, replace any worn-out components to ensure optimal performance. You can also use this opportunity to clean and lubricate the parts you’ve removed.

Make sure to inspect the inside of the receiver and the barrel for any dirt or debris. You can use a soft brush or cleaning patches to remove any buildup that might affect performance.

Reassembling Your Mossberg 500

Now that you’ve successfully disassembled your Mossberg 500, the reassembly process is just as important as disassembly. Here’s how to put everything back together:

Step 1: Reinstall the Bolt and Bolt Carrier

• Insert the bolt carrier group back into the receiver.
• Make sure the bolt is properly aligned within the carrier and moves freely.
• Push the action bars forward and check that everything is seated correctly.

Step 2: Reinstall the Trigger Group

• Place the trigger group back into the receiver.
• Align it properly and reinsert the trigger group pin.
• Tap the pin back into place using a punch tool if necessary.

Step 3: Reattach the Forend

• Slide the forend back onto the magazine tube.
• Reinstall the retention screw and tighten it securely with a screwdriver.

Step 4: Reattach the Barrel

• Align the barrel with the receiver and the magazine tube.
• Thread the magazine cap onto the tube and tighten it by hand.

Step 5: Final Check

Before heading to the range or storing your shotgun, double-check that all parts are properly reassembled. Test the action by pulling the trigger and cycling the action a few times. Ensure that the shotgun is functioning smoothly without any odd sounds or misalignments.

Troubleshooting Tips for Your Mossberg 500

If you experience any issues during the disassembly or reassembly process, or if your Mossberg 500 isn’t functioning correctly after reassembly, here are a few troubleshooting tips:

• Problem: The action is stiff or doesn’t cycle smoothly.
• Solution: Check for any dirt or debris in the action bars or bolt carrier group. Clean and lubricate all moving parts.
• Problem: The shotgun won’t load properly or misfires.
• Solution: Inspect the firing pin and extractor for any signs of damage. Replace worn parts if necessary.
• Problem: The trigger feels loose or inconsistent.
• Solution: Check the trigger group assembly and ensure that the trigger pin is fully inserted.
