I have an AUG A3, and I've had virtually no trouble with it. Of course it's much more expensive, but I heard some bad mojo from folks who had owned the MSAR, so I went with the real deal.
One of the first things you do with either the MSAR or the AUG is cut a finger about halfway off. That's why they make an instruction manual, which in my case clearly states that you should grasp the handle from below, not from above. The first AUG I handled (in a store), ended up with a significant amount of my blood on it. But even though I've mastered the manual of arms for the AUG, I've installed a Manticore just to be on the safe side.
As I said, my Steyr has given me almost zero trouble so long as I stuck to bullets of 55 grains or above; the 50-grain Federal hollow points caused many FTF issues, but then they didn't work in my AR either.
PS: DO NOT waste your time on Russian steel case ammo. Doing so is asking for trouble.
