That's what I've been thinking, The Demongod, and that's why I want the Dragunov in the game, or at least some sniper rifle that is particularly designed for that exact scope. I loved using the Dragunov's scope in Arma2, it was the only sniper I was good with, and so I'd love to see it in Arma3 as well.

Ah, I did not know this. Thank you, Goose. I suppose this makes the scope useful, but I liked it in Arma2 where you didn't necessarily have zeroing, and would rather have to use your calculation to see where you should aim with the scope in order to strike the target.
While zeroing is realistic and useful, I personally think it still dumbs down the sniping and makes it uninteresting and too easy. IMO, Zeroing should be possible to turn off.
