To replace a rubber seal in a 788 BB Scout, first ensure the firearm is unloaded and safe to work on. Disassemble the relevant parts to access the seal, typically involving removing screws or pins. Carefully remove the old seal using a small tool if necessary, clean the area, and then insert the new rubber seal, ensuring it fits snugly. Reassemble the firearm and test for proper function to ensure the seal is correctly installed.
