Currently, rifle zeroing in this game can be drastically altered, in scope, almost instantly by mashing a few buttons. Re-zeroing a rifle scope this quickly is - frankly -completely unrealistic and makes sniping easier than it should be. I would recommend: A. Fix all scopes to be static (like the DMR) and force players to calculate shots using mil-dots. B. Add an animation and delay to re-zeroing a rifle. (Much like the generic bandage/cook-meat/blood transfuse animation) to prevent instant range-finding, pinpoint shots. Zeroing a rifle scope IRL is much more complicated than pressing a button. (http://www.ehow.com/...ifle-scope.html for those of you that care.) I can find no military or civilian scopes that allow for the "quick zeroing" feature we see in the game today. The status quo allows geared players (Rangefinders + zero enabled rifles) to make insane shots with relative ease.
