minimag leaking out back

[foodboy]

Hi
I finnally got out to play with my newly upgraded old minimag.
Just recently added hpa and lvl
10. I found it worked great but had a small leak out the regulator
at the back.
I changed the regulator seal but still had some leaking. I think I read something about older guns needing a new regulator when moving to hpa. my serial # is in the 6000's.

Thanks for any help

Is your velocity too high? Make sure your spring pack is liberaly oiled too.

Gun was crono'ed about 280
with just a light hiss out the velocity adjuster

Alot of times after installing a lvl10 you will need to relplace the BlowOff valve in front of the spring pack. By replacing it should stop the problem. First try taking out the blow off valve and put some oil on the holes and gas it up try that and see if it works. If not, then i suggest you to get a new blowoff valve.

I just finished taking apart my mag and oiling everything really well. Then I dry fired a few dozen times. I listened closely and I still have a back leak but it is quiter now. Guess I'll order a new blow off .

Thanks
