BlackVCG's ULT Thread

ULT w/ X-Valve question

Hey I know this is kinda dumb, but I'm thinking about getting the ULT on/off setup, but from what people tell me, it kinda defeats the purpose (in my opinion) of the X-Valve. From what i hear, it makes the trigger very light, but less reactive and easier to short stroke. (i know this doesnt matter with the Lvl. 10 and all, but i dont want to kill the reactiveness of the X-Valve)

Anyone have any experiences they can share with me? If i put the ULT in, will it mess up my trigger's bounce-back? Is there a way i can make it lighter without killing that kick-back? thanks.

It's been a while since I played with the ULT and didn't get to go to the IAO class on it.

I set one up for my brother in law yesterday and it works awesome -but has one issue - it seems to always chuff on the first pull after more then a 5-10 second break in firing. Does anyone know off hand what is up? It's an Emag valve drilled out with a ULT on a MM rail and Intelli frame. The body is a stainless no-rise.

Thanks,

Calvin,

Sounds like the infamous LX issue of having too tight of a carrier o-ring.

Check the carrier o-ring fit and make sure it's as loose as possible w/o leaking.

That should fix the problem.

I am having a little trouble getting my ULT to work properly. I've read all through here and seen a few similar issues, but I wanted to spell this out and see if I can get a definite answer.

I have a ULE with X-valve and intelliframe. It works perfectly with the original on/off, but when I put the ULT in, I get what seems to be shoot down in even slow streams of 5 to 7 BPS (don't get it with the regular X-valve on/off), and then a chuff, and occaisionally my bolt will not reset and I have to push it back. My tank is an 88/4500 that is putting out 950psi. I can rip off pretty high BPS with the original x-valve on/off but with the ULT it seems like I run out of air or something.

I suspect that the pin is sticking, so I took the ULT apart and oil the crap out of it. That didn't seem to help.

Oh, I've get 5 ULT shims in.

I hope ya'll have some advice for me, here.

ULT and Hyperframe

Would this a good combination or not neccessary?

[Plazmic]

Isn't the hyperframe electro? If so, then the ULT is not necessary.

so like I said, I'm looking to design a version that would help the STANDARD valve. a lighter trigger pull without sacrificing too much on the recharge rate. I don't care about reactivity.
this is why I'm looking for the measurements of the ULT pin. somebody, anybody with a ULT and some calipers.
I want to know what to start with.

Here ya go Electrician. I couldn't get the last two measurements because I'm afraid of bending the pin while taking it apart. Don't know how accurate ym caliper is either, it's digital. Hope this helps.

hey guys, i've read all the pages of this thread looking for an answer, but i havent gotten a straight one yet....

Am i correct in saying that the on/off assy for the ULT IS(?) the same as the stock on/off assy for the x-valve? i ask this because i want to remove the ULT from my gun, and try the stock on/off, as i bought the gun with the ULT already installed...

thanks for any help

They are not the same, but they are interchangable. There is an o-ring that goes with the stock that you will need to put back if you are taking out the ULT. Make sure you have that.

[spadge67]

thanks a bunch, i appreciate it...

*edit* also, is there going to be another o-ring in the gun i can use as a model when i get another one?

I'm afraid I don't have an answer to that one. It is very possible since AGD tends to use identical parts throughout the gun when they can. Try calling AGD tech support. They can tell you right off. You could also try PMing BlackVCG or Tunaman. They might have an answer on that one.

ok, heres the pic from agd's website, is the oring you mentioned the one on the bottom of the on/off? (left side in the pic) casue thats exactly what my stock on/off looks like

No, there's one more o-ring that sits down in the on/off hole in the X-valve with the standard on/off. This o-ring must be removed to install the ULT on/off. It's a little bigger than that one on the end.

I have mine at home with my original on/off. I'll take it out tonight and see if I can find a match for it in any of the other AGD o-rings that I have.

BlackVCG, Tunaman, can either of you be more specific for him? I'm afraid I don't have the exact info that he needs to get the right part. Thanks, guys!

ULT Still sticking

Ok, I'm up to all 5 ult shims, and a lvl10 shim, that's 7 total (LX=2) No chuffing, or short stroking problems, but not the friggin thing won't reset sometimes......

Valve won't fire with anything less that 4, huffs-chuffs @4...5 shims, and it starts to get better a few chuffs, and some sticking....from there it seems ok, but sticking..the LVL10 is fine it fires forward, and completely retracts. My AA 68/4500 was just filled today.

I also noticed the 5 on up the gun fires upon gas-up....

Your thoughts?

Thanks,

Rob
