It LOOKS pretty straightforward.....but how do you ( can you ? ) pull the trigger from the stock body on an AUG?

Do you mean from the trigger pack?

Pull pin, pull buttplate, trigger pack slides out, voila!

The triggggerrrr.

Ta da.

I believe the OP is talking about the trigger and not the hammer pack.

Just curious as to why you want to remove the trigger?

HK's "trigger pack" causes the misnomer relating to the AUG "hammer pack".

Not sure why you want to remove the trigger, but knock yourself out:

Ensure the gun is empty and safe then break it down to just the stock.
Remove the trigger screw (and washer) with a 3mm hex key.
Use flat pliers to pull out the sear (dual linkage rod) from the back of the stock.
Remove the trigger.

-----

Insert the trigger into the stock.
From the back of the stock, reinsert the sear, pushing forward with the flat pliers until the sear stops at its forward most position.
Put the safety into "fire".
Insert hammerpack (cocked) into stock and secure it with the sling pin.
Slide the sear rearward until it lightly rests against the slide (sear) of the hammer pack, but does not release the slide (thus causing the hammer to drop) i.e. DO NOT PRE LOAD THE HAMMER PACK SEAR.
Retighten the trigger screw (with washer).
Do not over tighten.

No such thing as a "trigger pack" on an AUG.  There is a trigger and related sear parts, and a separate "hammer pack".

I don't.  I am curious if it is easy as it looks or not.

THANK YOU, MY GOOD SIR!!!  I KNEW there had to be a bit of meat to the subject!!!!!

My bad, wrong verbage. Got hammered on a vette forum for the same thing.
Life is starting to kick my ass.

I hate it when that happens...
