I have a KP2-DF that has started to leak down the barrel. This KP is a constant air setup and it seems the leak is quieter when the pump handle is all the way back, when it is all the way forward it is quite loud. I put some oil in the line and it stopped the leak for a couple dozen shots, but then it came back.
Does anyone know what might cause this?
Extra credit question. I have another KP that, with c02 attached would do nothing when pumped and fired, no noise, no leak, nothing. Now, I removed the bolt and noticed that it had no o-rings on it, would this cause the gun to do nothing? Or is it a bad valve?
