My farther and i recently purchased the x valve from agd his arrived before mine, we both put them in 68 automag classics his works like a dream mine on the other hand doesn't I need help. The problem is when I engage air to the bolt no leaks no problems once I fire the gun it starts leaking out of the barrel, if I put slight pressure on the trigger it stops. I have swapped body's with dad's auto mag and same problem so it's in the bolt anyone have any ideas thanks
