Need help sighting in Steyr AUG

[Remington]

I just bought a Steyr AUG A1 and i cant seem to figure out how to sight it in.
There are 3 turrets on the scope,but only one will move and it is just some form of screw.Does anyone know how to adjust the scope on an AUG,or have a link to a webside that does? Please forgive my spelling,english is not my native language.
