Here is the Zastava M76 http://en.wikipedia.org/wiki/Zastava_M76 sniper scope I've made, it is very similar to the PSO-1 scope used on the Dragunov.

and while I where at it I've also made few more scopes, just to see how they would compare to the first one.

For me these last two turned out to be pretty good at taking out targets at long range, especially the one with the inverted chevron.
