ULE trigger kit help

[Babylon 5]

I just bought a used mag that had the ULE trigger kit installed on it and was wondering how I would tell if it's tuned correctly? Cause when I air it up and pull the trigger just right it will go almost fullauto, then when I stop it I can hear air leaking in the valve area until I pull the trigger back for a second then release it it stops.
Is this normal or do I need to read up on how to tune the ULE trigger kit?

it seems you need to remove a shim or two

the ULT uses shims to properly tune the trigger for the body its installed in



Adding more shims allows the on off valve to open earlier with the trigger release
removing shims does the opposite

you need to set the shims perfectly or if added too much youll get the problem your experiencing now, Or youll get shootdown or a gun that doesnt fire


also you might get leaking from the orings on the top of the on off...for the on off body and/or the pin.....i have that problem with my friends Xvalve.....and i dont know how to solve it, strangely enough the ULT in my AIR valved mag doesnt get any of those problems

Since his question was answered, I'd like to ride on his thread and ask. Where would I find a ULT rebuild kit? The ULT I got on my mag is pretty much in need of a full rebuild. Any help?

no idea......i need some shims as well.....but im starting to wonder what would happen is if i found a washer that fit....might be worth 4 shims hahaha

you can use level 10 shims if you have any laying around .... 1 level 10 shim = 2 ult shims
