no different between this 2 guns... only a little bit the color & the muzzle break, and austria have many different versions in use
one with laser sight, laser pointer, night vision, transparent magazine, normal magazine, short barrel, long barrel, bigger magazine (12 shots more).
and of course the color is variable... my AUG was a little bit darker then the one of my colleague...
the gun on my pic, is an STG77 from the Austrian Army.
The one on your pic also!!!
or both from australia... but i know that we have both versions on the pic, in use at our army...
austria´s army had the stg77 (austrian aug) since 1977 in use... since there exist soooo much new versions with little changes in design and triggerunit. One example is the firing pin: in our old versions it has 2 little metal pieces to be handled from the trigger... our new versions have 3 of this pieces...
the "nipple" of the barrel (in german we say "laufwarzen") are very plain and less then in our new version...
you cant see the changes from outside, but if you demount the gun you will see little changes.
i believe that australian f88c is this AUG version, we use as our "new" STG77 version... they are shuffled in our army ^^
We dont have one type of this gun for all of our Soldiers... but i can say, its a really beautiful gun without any recoil XD ok..little bit, but a watergun has more recoil
omg im sry for my english -.-
