I didn’t even notice it at first. When I raised the reg to see if I could shoot heavier slugs, there was nothing out of the ordinary. I used the bleed screw before lowering it back down. Then I looked at it and noticed that both the regulator and the pressure gauges were at 1000psi. I filled it up and didn’t check it for a few hours. It went back down to 1000 or so. I loosened then tightened the bleed screw, but it didn’t seem like it was leaking there. I filled it and shot a couple of pellets, just in case the valve was stuck. I refilled it several times and watched it and looked for obvious leaks. The one time I could hear the leak. It was gushing air inside the forearm near the reg and bottle connection. It emptied fast enough to cool the bottle. You had to have your ear next to the stock to hear it, but it was flowing. My initial thought was that maybe the regulator didn’t like the higher pressure. I increased the regulator a tiny bit, just to have some movement on the internals to see if anything changed. I don’t hear it, but it still leaks. I gave the bottle a quick twist, but I need to degas it and check it. I don’t think it’s the foster valve. But it’s in the general area. I don’t know much about the regulator, I would’ve thought if it degassed that fast, the regulator wouldn’t hold the set pressure and it does. But, again I don’t have a grasp on the mechanics of the regulator (yet). It seems to stop degassing once it hits around 1100-1400. I guess I need to pull it from the stock. Here is what the gauges are sitting at now after sitting overnight. I also did the balloon check. The reg setting is approximately 2000psi.
