The Steyr AUG is what the New Zealand Army and other foreign armies carry that your thinking of.
I have some experience with the AUG. I don't personally like the ergononics of the weapon, but many do.
MSAR (Microtech Small Arms Research) makes an AUG knock off, of sorts. I don't have experience with this rifle first hand, therefore I cannot comment on the type of action or it's reliability compared to an actual Steyr.
