Steyr AUG upgrade?

[ether]

Hey, what parts were upgraded on the original AUG awhile back? It seems like it was a new bolt or something....was that all? Also, can you still get the upgraded parts if you need to? Or do you just have to hunt and peck for a kit on the For Sale boards? Just curious. Thanks!

While I have seen minor differences in bolt carriers, I don't know the upgrade patterns on this weapon. Someone else here might.

If not, these guys should know;
