So any diagram will work. I think there is one stored on this forum but someone will have one. You can unscrew the receiver end cap and the ring behind it along with the trigger with no worry. Then you need a spring compressor to put pressure on the retaining block/spring guide. Then loosen the bolt on top....actually the bottom as the receiver will be bottom up...The the spring and guide will slide out. Often on older guns the piston will have to be taped out. Early KG pistons have a threaded stud sticking out the face. The seal slides on it, then a dished washer or collet then a special cone shaped nut. They are often damaged if the gun was shot with a bad seal. If that is the case report back and several here can go through the fixes.
They are simple but nicely made guns, easy to work on and parts can still be had...
