What is this ULT Full Auto mod

[PnueMagger]

I heard about this full auto ULT mod. Is it just over shimming the ULT and pulling the trigger all the way? Or is there very carefull trigger bouncing happening here? Could someone point me in the right direction?

If it is just overshimming the ULT...Consider my Pnuemag fully auto.
1 lvl10 shim = 2 ULT shim right?

Extra shimms makes a full auto trigger pulled all the way. Thats about it.

Your conversion is about right 1 LX= 2 ULT

sounds right. Also, you can shorten your ULT pin of too many shims makes the ULT itself not fit into the body of the gun. In effect, shims make the pin shorter.

how fast full auto are we talkin' here....

Zak Vetter 31bps fast or like 18bps fast. Please be 18 cause I only have an apache hopper.
Also, is it fully cycling? Is it controllable, like when I let go of the trigger it stops?

Thansk so far for all the great responses!

Not 31, I've seen about 19bps using this version. Yes it is fully cycling.

www.zakvetter.com has a lot of information on the subject.

my personal xvalved mag has had a consistant 19 BPS with a ULT that had 1 lvlX shim and i ithnk 3 ULT shims

mine is set to bounce as of right now, 9 shims in there and to make it bounce all you have to do is touch the hump of the trigger, nothing to it. (works much better on 850 output tank than my P.O.S 800) and its pretty fast, probably in the 15+ range, and walking it is SUPER easy

Take off the top part of the on/off pin. Just to give you a fair warning, it will seriously mess it up pretty good.

[PnueMagger]

what?

The ult pin will bend for sure, and the orings wont stay in the top of the on off chamber and leak.

No s*** shirlock, of course it will mess it up.

I'm not getting this whole, "full auto mod" of the the ULT. You set the ULT up with as many shims as possible till 1 it leaks or 2 it doesn't fire (depends on the valve) then back off one shim so it works without leaks. Pretty simple. There is no "full auto" in the sence of the term "full auto". The lvl10 shim is .010" thick and the Ult is .005". Using 1x lvl10 shim is equal to 2x ult shims. That is the difference between the two of thoughs. In reality it is all about trigger control and imput pressure to make the mech mag sing.

4 shims in the ULT and 1000psi input here; certainly not "full auto" but fast enough
