Xvlalve - level 10 - ULE trigger

So I've been through about 3 entire o-ring rebuild kits over short while. Seems like replacing the o-ring in the cradle fixes it temporarily (for the dayor so) but then next time I go to play: air it up, wait a few minutes, BAM! first shot waaayy hot, then the rest of the shots seem to stay consistent until I wait another minute or so to test it again (unsafe for play ).

When I take it apart the o-ring in the cradle seems to always move a little out of place, could it be that?
