Are you going by the ingame descriptions for the magnifications? If so, those are wildly inaccurate and need to be cleaned up. The DMS for example doesn't have the 2x-4x magnification it claims in the description, but rather 6x-12x.

40x? That's ridiculous. Most tactical long range scopes have variable zoom somewhere around 5x-25x

i was talking about the ingame stats indeed, and 40x scopes deffinetly are used in reality

Ho yeah? Give me one reference of someone that uses a 40x scope in a tactical situation. Just look at major scope manufacturers' (Schmidt & Bender, Nightforce, US optics, etc) LE/Military scopes, you'll find out. Don't argue on this.

Scopes with this much magnification only serve to shoot paper targets, or prairie dogs.

40x is a good magnification for a spotting scope. Not a rifle scope.

longe range sniping, used on anti-materiel rifles.

Hahahaha! Amazon.com reference... Splendid.

Which one? The $89 Barska? The $79 Ultimate Arms Gear? C'mon, get serious.

40x lol What is he shooting an F class bench rest match ?

High end on magnification scopes top off at around 25x.

im getting to old for this shit, go ask someone who's answer you thrust.
