Unity sniper scope tutorial?

Can anyone point out a tutorial on how to make a sniper scope aim down sights sort of thing? I mean like call of duty ect.

I answered a question about this some time ago - click here to read it.

you need to download 3ds max in the student autodesk website, then import it into 3ds max as a sketchup file then export as a FBX file.
thats what i do anyway.
but if you do building you have to be carefull sometimes not all of it comes out.
