OK i am having leaking problems. i didnt have these problems untill i got the ule body. let me give you a discription of my gun. i have the retro valve with the level 10, and ult. ule body, and hyper frame. at first it seemed that that the bolt was sticking in the body, so i put lube on it and that cancelled the problem. now i am leaking naturally i assumed it was the on/off so i changed shims from 1, 2, 3, 4 i cant fit 5. 3, and 4 seem to work, but as i shoot a string, it starts leaking again. so do i have a bad ult on/off? i have changed o rings. is there any other problem that could cause leaking? it leaks down the barrel or body(if no barrel is on). also as i string paint the gun jams, i have to use my battle swab and push the bolt back to get it to unjam. what could cause this problem? last if i turn my velocity up higher than 280 the gun leaks out the back hole. what could cause this problem?
thanks for the help.
