1. You will need to remove the shroud cap.

2. You will need to remove the baffle retainer with a spanner wrench or some really pointy needle nose pliers. here is a link on the pliers i use in the link below.

3. Now you can let the baffles slide out of the shroud. 

4. There will also be a air stripper on the barrel in the shroud. If it does not come out you will need to unthread the shroud to remove it.

5. If you removed the shroud you need to put it back on the airgun.

6. Now you can add our adapter on the shroud and add a suppressor as well.
