I dont have Battlefield 4 yet, also not yet the XbONe, but on Battlefield 3 i use the SVR..i think...the 30-06 rifle with a decent scope and from that I cross mapped multiple times a sniper with a better gun at 205 meters. :P it was on Tehran Highway. I was on a small tower and he was camping in the rocks across. most of my snipes were headshots on him.
