i can't take my valve out by just unscrewing the quick release screw because the on off pin sticks into the body and won't come out until i take the whole marker apart and push the on/off with my finger. i've tried degasing it and the pulling the trigger some more but the sear won't push it up far enough. it wasn't really a problem until now because i'm trying to get level 10 working and i don't like having to take my marker all the apart just to get to the bolt. any ideas/solutions to my problem would help.
