Step 1: Remove the Barrel Nut

The first step is to remove the barrel nut, which holds the barrel in place. You can do this by hand, but it may require a bit of force.

  1. Locate the Barrel Nut: The barrel nut is located at the breach end of the barrel. It’s a large nut with a flat top.
  2. Apply Gentle Force: Use your hands to apply gentle force and unscrew the barrel nut in a clockwise direction. It may take a bit of effort, but don’t apply too much pressure.
  3. Set the Barrel Nut Aside: Once the barrel nut is removed, set it aside safely.

Step 2: Remove the Foreend

The fore-end, also known as the pump handle, is removable.

  1. Locate the Fore-end Pins: Locate the two pins that hold the fore-end in place. They’re typically on the sides of the shotgun.
  2. Pry the Fore-end Away: Use a wrench or pliers to gently pry the fore-end away from the shotgun. Work carefully to avoid damaging any surrounding components.
  3. Remove the Fore-end Pins: Once the fore-end is removed, remove the pins from their retaining slots.

Step 3: Remove the Trigger Group

The trigger group consists of the trigger, safety, and hammer. These components are removable and relatively easy to take out.

  1. Locate the Trigger Group Screws: Locate the two screws that hold the trigger group in place. They’re typically located on the underside of the receiver.
  2. Remove the Trigger Group Screws: Remove the screws using a Torx T-15 screwdriver (for some models) or a standard screwdriver.
  3. Pull Out the Trigger Group: Gently pull out the trigger group from the receiver.

Step 4: Remove the Magazine Tube

The magazine tube holds the shotgun shells and can be removed for cleaning.

  1. Locate the Magazine Tube Lugs: Locate the two lugs that hold the magazine tube in place. They’re typically located at the breach end of the shotgun.
  2. Slide the Magazine Tube Off: Slide the magazine tube off the shotgun, working slowly and carefully to avoid dislodging any shotgun shells.

Step 5: Remove the Receiver Housing

The receiver housing can be removed for more in-depth cleaning and maintenance.

  1. Locate the Receiver Housing Screws: Locate the two screws that hold the receiver housing in place. They’re typically located on the sides of the receiver.
  2. Remove the Receiver Housing Screws: Remove the screws using a screwdriver.
  3. Pull Out the Receiver Housing: Gently pull out the receiver housing from the receiver.

Step 6: Reassembly

Reassembling the Mossberg 500 is essentially the reverse of disassembly. Make sure to apply the following steps carefully to avoid damaging any components.

  1. Replace the Receiver Housing: Start by replacing the receiver housing.
  2. Replace the Magazine Tube: Next, replace the magazine tube. Make sure it’s seated properly and the lugs are secure.
  3. Replace the Trigger Group: Replace the trigger group, ensuring it’s seated properly and the screws are tightened securely.
  4. Replace the Fore-end: Replace the fore-end, ensuring it’s properly seated and the pins are secure.
  5. Replace the Barrel Nut: Replace the barrel nut, applying gentle force in a counterclockwise direction until it’s securely tightened.

Important Safety Considerations

When taking apart and reassembling the Mossberg 500, it’s crucial to follow proper safety precautions:

Always use appropriate safety gear: Use eye protection, hearing protection, and a non-triggering trigger guard.
Handle components carefully: Avoid touching any electronic or mechanical components with your fingers, as oils from your skin can damage the material.
Cleanliness is key: Ensure the shotgun is clean and free of debris before reassembly.
Inspect for damage: Inspect each component for damage or wear during reassembly.

By following these steps and guidelines, you’ll be able to take apart and reassemble your Mossberg 500 shotgun safely and efficiently. Remember to always follow proper safety precautions and handling practices when working with firearms.
