I bought all the part to create a UL xvalve mag . right now with an HP tank the trigger pressurizes and i can hear it click and feel pressure behind the trigger. the prob it wont shoot. need some advice before i go crazy. i did up the velocity/pressure withe the back adjuster all in and all out. so, do you guys think i need to bring out the trigger rod? is my on/off poopie?

thanks
