ULE Trigger Tuning

[openboater]

I picked up a ULT at the IAO from a Tech that attended the Tech conference. I wish I could have made it Tuesday.

The nice guys at the AGD booth installed it in my new X valve. I came home and started playing. First I installed the level X from my other mag so I'd know the LX was all OK.

I installed the new X valve w/ULT in a new ULE body and new Y grip and it would not shoot. installed the original on-off and the gun shot. So after getting some advise in the Tech forum, I called AGD and they told me to install more shims. ULT shims are .005 thickness and LX shims are .010.

I installed .020 total in shims and the gun shot well.

This afternoon I installed another shim up to .030 total. Trigger feels great.

I lengthened the sear rod so my firing point had very little pre-travel. I can slip a piece of paper between the rod and the back side of the trigger, but not much more.

Then I removed the trigger and drilled and tap'd for a 6-32 and installed a post travel stop.

After playing with the 6-32 screw I have total travel down to .110 inches (110 thousands) Just under 1/8th inch. You need a little excess space so the gun will shoot every time.

and boy is it sweet. I've run a bunch of balls thru it and no problems so far.
After I get used to it I will try a little more shim.

You can see in the poor quality pic how little traved the trigger stop allows.

more later.

When the ULE Trigger is in the store, I will buy one... I am afraid though that I will be on vacation when they come out and be sold out when I get back..

hows the reactivity?

[Kevmaster]

about 1/3 of the orignal reactivity

[openboater]

Yes, my reactivity is less. I would descrbe it as softer, not that snap you used to feel.

I have not broken a ball(double loaded) due to short stroking yet. but I only shoot 6-7 BPS max and I don't fan or walk my trigger.

why is it that no matter what we say ppl feel the need to adjust the trigger rod, lol?

[openboater]

I used to agree that adjusting the trigger rod length was a no-no, but I now believe that ULT changes that. Before with a set length pin, the geometry was correct with a set length rod, but now that the pin is a modifiable length due to the sims, the rod length can also be modifiable.

Just like LX made ULT possible, ULT makes adjustable rod possible.

Try it, you may like it !! if not, just set it back to the original length.

[GatoLoco]

so the reactivity ratio is the same, so you still notice the kick back of the trigger, because you are used to a lessend pull? (if you can understand wtp* i mean)

[edweird]

yeah its still noticable... infact you need to keep the reactivity low to get shortest distance between the fire and recharge points of the swing without having your trigger runaway

[Jerhew]

wow i didn't realize you'd be able to get the trigger shorter as well as lighter...
i'd still like to see what Tom thinks of this before i'd mess with the rod length...especially because everyone always made such a big deal about NOT messing with the rod

There have been different length on/off pins for years. They varied in length by .005"...the same thickness as a ULT shim. So nothing has changed there.

Don't mess with your trigger rod. Or at least don't complain about your gun not working right after the length is changed.

boater: use the shims toadjust what you did with the trigger rod...it works much better

Muummmmm (rubs hands together) we are going to sell a bunch more replacement bolts!! YEAAAA!!!
