Step 1: ENSURE THE WEAPON IS UNLOADED

Always ensure your weapon is unloaded prior to attempting to disassemble your weapon!

With the bolt moved to the rear you can look inside the chamber to ensure that the chamber is clear

Step 2: Unscrew the Magazine Cap

Unscrew this by hand, if you can not do it by hand for some reason place your rag over the cap and gently use a pair of pliers to loosen it. After doing so you will be left with what is shown in image 2

Step 4: Remove the Forend, Bolt and Bolt Carrier

Flip the shotgun upside down and use your fingers to push on the spring loaded metal strips located inside the shotgun to flatten them out. This will release the forend, bolt and bolt carrier and you can pull it out just as the barrel was pulled out. You will likely need to press on the strips while pulling the forend. This step is tricky to describe however is easy to complete.

When you have completed this step you will be left with what is shown in image 4
