I have a KSC USP mag where the flow valve leaks from both the exterior button and from the actual valve/gas port on top of the mag. I have tried several silicone oil applications and working it into the valve from the side and the top but it still leaks. What is the cause of this? Is the valve spring weakened or a dead o-ring perhaps? I can order a new valve but I'd like to try to fix it myself.
