Air blowing out the back of my retro mag, please help

[warrior18]

Hey guys I have a z-grip, lvl 10 retro mag with a mini-mag body. Air started to blow out the back of my marker so I changed the regulator piston, when that didn't work I tried changing spacers in the level 10, then I lubed all my o-rings again, still didn't stop it. I really don't know what else to do so any advise would help. Thanks.

did you just put level ten in, my rtpro did the same thing right after i put in level ten. i foret exaclty what i did but i messed around with it and it stopped leaking. I think venting out the back means you have to high a pressure(your velocity is ajusted to high) which would happen when you put in level ten.

what is your input pressure? have you tried changing that or the mags regulator? does it continue to leak if you shoot?

No I have had my lvl 10 in for awhile now, it was ripping one day then the next week it just blew out the back. My input pressure in 850 and I have tried screwing my regulator all the way in and then all the way out. Yeah I thought about the pressure being too high but that makes on sense since it was working fine at that pressure. Thanks though guys I really appreciate the help. Please don't stop though.

what is your level ten setup? maybe changing springs would let it operate lower. do you have level 7 parts... you could try them to see if it is lx related.
