Here is a model of the Steyr AUG. I made this model before I made the AUG-50M3. This is one of the most realistic models I have made. I included the grip, scope, original iron-sights, working bolt, and an accurate hand guard and stock. I know the mags not curved because I couldn't curve in LDD that makes it look realistic.
Here are some pictures.
Here's a picture of the mag. Sorry it's not curved again.
