Have you shot a few times (with or without paint)?
Sometimes it can be as simple as the fact that the bolt has stuck forward a little (check around it for shell/damage etc).
What I did to mine was to simple turn the reg all the way down (so no input to gun - hence no leak), then turn up gun a little at a time while chrono'ing it.
Try putting on some PTFE tape, or plumbers tape on the threads, it should seal them, but as said before check the orginal banjo, youll need to re-apply the PTFE every time its taken apart though.
