Ok so i just checked exactly where the air is coming from. It is coming from where the probe goes into the barrel. I also placed a piece of blue tape where the other post says to check and there is no air coming from there. It could be that the O-ring is damaged but cannot be seen with the naked eye. I'm pretty good with taking things apart and working on them. I play around with remote controlled cars electric and nitro powered and have a good set of tools for such things. I do however agree that I should not have to take apart a $2200 item after only having it for 5 days. Forgot to mention that when the bolt is closed there is about a 1mm gap between the bolt face and the frame/receiver. I don't know if that is normal or not.
