I have an Xvalve with a confounding leak.
It leaks from the middle of the gun. I can hear it from the barrel, feedneck and near the trigger.
It leaks when the trigger isn't pulled. When I pull the trigger, it continues to leak but dies out and stops leaking after 4 or 5 seconds.
I've tried several carriers and carrier Orings.
I've tried new on/off top orings
I installed a ULT.
Swapped out the Reg Valve Pin assy
I tried a different rail/body/sear combo.
I tried a different bolt.
The leak persists despite any of these.
Any ideas?
