I live in howell nj. looking for a good tech that could help with my x valve setup. Gun works fine with the classic minimag valve. Just got an xvalve and am having problems after problems. mostly air leaking down barrel when trigger is held in. I know its the on/off valve. or thought that. i have changed every o-ring and cant get it to stop. i have tried two diffrent on/offs still same problem. Have never had so many problems with a valve. I just got the thing new from agd. It hasnt worked right since i got it and am pulling my hair out trying to figure the thing out.
