leak

[TheBigRaguPB4L]

i should know this, but i'm a bit rusty since i've been out of paintball for like 4 months. i have a zgrip mag with a retro valve. i put some air on and it starts leaking heavily out the front. i hold the trigger down, and slam on the back and it stops. pull the trigger and it starts leaking again. i'm guessing the spacer on it is to short cause it's going to far into the power tube. but as i said before, i'm a bit rusty. if anytone could get back to me, it would be much appreciated. thank you.

Well you may want to whip out the manual but off of the top of my head. It may be the PT o-ring, the pt-spacer length, a damaged powertube(base), and ummmmmmmmmm?????? Maybe a worn out bolt?

It's either too short of a PT spacer or a broken PT o-ring. With leaks down the barrel, you want to put in a spacer one size shorter. Just unscrew the PT tip and find out what size spacer you have in there now and check the o-ring to make sure it's in good condition.
