The Soviet scopes were based off the German ones which is why they look similar in fact they may have even bought telescopic scopes from Germany during the non-aggresion pact. Im not sure about Soviet variations but the Germans did have other scope variations for their rifles such as Major Konig's(I hope I nailed the spelling) sniper rifle scope as seen on enemy at the gates.Russian and German have the same look which doesn't seem historically accurate to me. Since I haven't handled either a Russian or a German WW-II sniper rifle I don't know but the later Soviet scopes have a different reticule with range finding gradients on them. I expect someone here can tell me the difference between WW-II scopes and later Cold War models.
On a map like Barashka you wont be hunting any GOOD snipers with IS, because you'll be dead at ranges which you cannot even discern the sniper.I don't like to use the scope, it's a ***** to use, harder then the ironsights.
And it's not as satisfying as using ironsights either.
Don't like being the sniper (sharpshooter) too, I prefer to hunt the sniper!
...unless I go Prone, and because of that, It reduces my mobility and offense, so I am left to camp, which is something I hate to do...
