Assuming there's a gas hose connecting your bottom line to the gun body, you may need to get a front bottle mount for the gun.
Once the hose is removed from the gun, you screw the ex chamber into the bottle mount then connect the hose from the bottomline end to the expansion chamber. You may need to buy a shorter hose and some elbows (new connectors).
If you take your gun into a paintball shop you should find they'll either tell you exactly how to do it, or if they're nice and you buy the parts off them, they'll do it for you!
