I thought I could find some guidelines somewhere on that internet thing but have been unable. Any assistance would be much appreciated.

I know the info can be found if googled hard enough, but i don't know where. I can tell you that the AX triggers can not be adjusted down as far as the AE triggers, since i don't think that info is readily available.
Good luck!

I would suggest to read all the posts on this thread including the best advice from "Lowlight". Hope it works for you.
Just to explicitly add Frank's comments on user-level AI trigger adjustment in general:
TL;DR - Put the wrenches away. Just shoot it.

I too would like to know for sure if you can adjust the trigger or not. I am very competent with triggers of all kinds and have rebuilt and stoned several different brands to get a better cleaner break. If it is not end user adjustable then no big deal as they are pretty damn good, but with the 2 AW's I have owned I notice a small amount of creep in the second stage. It is not bad and is fairly predictable, but I like as clean of a break as I can get.
I think in the quote of LL above he is generalizing about people who don't know about a two stage trigger, but in the thread where he said that I think the guy he was quoting was taking about the creep I am describing. A two stage trigger does not need any creep in the second stage to operate properly. However this may be intentionally put there by AI for a safety factor given these rifles intended use. After all they are a field grade battle rifle not pure target rifles. I understand that and appreciate it, so if I have to live with a small amount of creep no big deal considering what all else the AI rifles bring to the table.

You can adjust the AW triggers down to feel very nice. I'm not a fan of how they feel from the factory and have shot thousands of rounds through mine that has been adjusted down. And Blackbrush is correct in that the AX can not be adjusted down nearly as far as the AW.

There's no danger in adjusting the trigger, provided you do it safely and buttstroke the rifle to make sure that the sear purchase is sufficient and the striker won't fire unexpectedly.
If you are nervous about trying it, keep track of the adjustments you make so that you can return it to where you started from.

bward & Grahm thanks for the input that is kinda what I figured. I have never taken any time to look at the AI triggers as they are pretty good but I think that will make a good weekend project. It just had me wandering after a few of the post in this thread and the one linked which I had read when it was new. I guess its like anything communication is not always the best even at the factory level or maybe things are not relayed exactly 100%.
Take it for what it is, but your comment on creep reminded me of this post (just quoting another person who knows much more than me):
"AIAW's trigger over-travel - Deliberate design?
When you fire the AIAW you'll notice it has some over-travel after the sear breaks. Some people may mistakenly assume this is flawed trigger creep, but I believe it is a deliberate design decision.
Upon inspection of the AI trigger, you can see that after the sear breaks the trigger has a few millimeters more over-travel where it provides extra clearance for the entire mechanism. The further you pull, the wider the gap between the trigger and sear becomes until you could fit a coat hanger rod through it.
I believe this is being done specifically to ensure absolute reliability. If dirt was caked into the mechanism the AI trigger has a better chance of still clearing the sear. The TRG trigger has much tighter tolerances in terms of clearance (and no over travel). Although my TRG trigger has been absolutely reliable, in very dirty situations my feeling is the AI is less likely to have problems due to its design. "
Taken from XOR in this thread.
I can tell my AIAW has been mucked with and, while its perfectly functional as is (given Graham's butt-strike test and fast bolt throws to ensure safe function), I so wish it was just left as stock.

ericthebeard, I am talking about actual creep in the second stage before the trigger brakes. It kinda makes the trigger feel mushy...

Overtravel is not creep. Some AIs have less overtravel than others.
I don't mess with the first stage adjustment screw (the third one in the middle). I adjust the trigger weight screw (closest to the muzzle), then adjust the sear engagement screw (the one on an angle above the trigger) until the rifle won't fire on a hard buttstroke.

I specifically contacted AINA about this and they said basically send it in (to VA) and they'll re-set it. Sounded like they really want to make sure its properly done, which goes hand-in-hand with the lack of adjustment information from the factory.
Well, more specifically, I never found anything definitive on re-setting the trigger other than that convo form AINA. All other internet searching (and I work for the internet) was vague and incomplete, though there are bits and pieces on SH about the function of the two adjustment screws there's nothing about factory settings.
