How to disassemble a Mossberg 500?

Learning how to disassemble a Mossberg 500 will take you only 2-3 minutes. By the time you’re through with this step-by-step guide, you’ll be able to do it confidently and conveniently on your own.

To begin with the process, you need two things. These include:

  • Mossberg 500
  • A screwdriver

You can use a punch tool, an Allen wrench, or even a pen in place of a screwdriver. If you have these, you’re good to begin.

Before you proceed any further, we need you to be familiar with two processes, i.e., loading and unloading. If you’re not aware of how to load and unload Mossberg 500, watch this two-minute tutorial. It’s for your safety.

Step 1: Clear Out Shells

First, superficially wipe off your shotgun with a piece of cloth. Be very gentle and polite with this movement.

Ensure that there’s no red dot showing, and the safety is on. Point the shotgun’s head away from yourself and check the magazine tube and chamber area to ensure there are no shells. You may place the butt of the gun on your lap when doing so.

Step 2: Remove the Barrel

Now, open the action of the shotgun halfway. The action of the gun basically refers to the part of the shotgun that’s located between the forend and the ejection port. Check out the image below:

It’s not the Mossberg 500. But the part detected action happens to be the same.

Now, unscrew the barrel from the top. It will be a swift counterclockwise movement. You can do it with your hands. There’s no need for tools at this stage. Just pull the barrel forward, and it will detach.

Step 3: Remove the Trigger Group

Here comes the only step that demands the use of a tool. Use a screwdriver, an Allen wrench, or a punch to push the housing pin outwards of the shotgun. And then pull the trigger guard of the gun downwards. It is a delicate process, and we advise you to be super gentle. Any rough treatment may result in damages.

Once you’ve removed it, the cartridge stop, and the cartridge interrupter will come off too. Just be careful with handling the housing pin, cartridge stop, and cartridge interrupter once they’re out of their position. That’s because they’re small and may easily slip out of sight. So, it’s best to use a container to store it.

Step 4: Remove Bolt Slide

Identify the receiver part of your Mossberg 500. The anatomy of a shotgun looks like this:

Now, remove the bolt slide from the underside of the receiver. Again, you wouldn’t need any tools for this step. It will be a manual process.

Step 5: Remove the Forearm

The forearm of the gun is the same as the forend. Push it in the forward direction (with the head of the gun pointing away from you). It will come off smoothly.

Step 6: Remove the Bolt

Your gun will look pretty much raw and bare by this point. Use your finger to push out the bolt from the hole where the barrel was positioned earlier.

Step 7: Pull Out the Elevator

The elevator is the part of your Mossberg 500 that lifts off the shell from the magazine level to the barrel level. When your shotgun’s bolt is removed, the elevator will be visible from underneath the receiver. It will be silver and will appear as a rectangular frame. Grab one edge of the elevator and pull it down to remove it.

Step 8: Recheck the Parts

The butt of your gun, i.e., the stock, the magazine, and the frame or cover of your receiver will remain in their position. The only parts that will be disassembled are:

  • Barrel
  • Trigger Guard (with housing pin)
  • Cartridge Stop
  • Cartridge Interrupter
  • Forearm
  • Bolt slide
  • Bolt
  • Elevator

You can remove the magazine tube too. Unscrew it from the receiver. However, it’s usually useful to do so. If you want to learn how to reassemble your Mossberg 500, browse this step-by-step guide.
