RAW HM1000x try to figure out and fix leak

This video is me disassembling and replacing some O-rings in my rapid air weapons HM 1000 X. In the end I am unsuccessful at stopping the leak but at least now that I’ve been into the airgun I have a better understanding of how it works. I later found out That there are O-rings inside the brass valve and I suspect that they are what need to be replaced. Comment below if you have had the same problem and what you did to fix it, I will post that inner valve O-ring replacement when I receive the new O-rings from RAW.
