I just recently ordered a Hatsan Jet 1 in 25 caliber. I like to keep some spare parts on hand for potential issues that my arise and that is the reason for my most.Is anyone aware of aftermarket valves (poppets, to replace the ones that typically break) for this airgun. Also looking for reduced power hammer springs...Finally, can someone point me to a video on tearing the Jet 1 down. I am sue I can figure it out but sometime its easier to watch how it is done the first time in case there are any tips or tricks to make it a bit easier...Thanks in advance.....Wbldon
