The last 3 or 4 times I've played, my regulator has leaked out of the hole while I'm shooting. it only does it during the first game or rope I shoot of the day, it doesn't do it at all when I'm shooting single shots over the chrono.
I already replaced the piston o-ring but that didn't fix it.
I have had the same problem, have cleaned and re lubed the entire gun multiple times, and still have not got this problem fixed. It seems to work for one or two weeks, but never fails to start bleeding constantly through the bleed hole on the reg mid-point. Its getting pretty frustrating and hope that i can find a solution soon.
