I'm in favour of saying that MIDA's unique version of what I believe to be Ranged Lens RLS3 is the best scope in the game, whilst RedDot-OAS, -OES and Truesight IS are all fantastic scopes, the former 2 allowing higher target acquisition and stability, the latter providing acquisition and a clear, open sight for open scenarios. If you're good with a Scout Rifle and can land 3/4 headshots repeatedly, you're probably a better player than the average Thorn user and have a decent chance of winning at mid-range, dramatically increased if you get the first shot.
