Need help: X-valve stops firing after 20 shots

[boatz]

Alright guys I have a tac-one with a x-valve. Valve is stock. After I air it up and can get about 20 shots thru it, then it looses pressure to the trigger. I have trippled Checked to make sure air is still going to it. Any suggestions. Thanks

Sounds like a bolt stick issue due to a carrier that is too tight. Tune your level 10 bolt setup. Remove your powertube shims, and install the largest carrier that does not produce a leak. Always use the same white oring in each carrier that you try. It is the oring that you are adjusting.
