They should just remove the target finder altogether if you ask me. All it does is takes all the skill out of locating targets. Just a stupid attachment. It wouldn't be that bad if the dual band wasn't in the game, but it's basically just another, cheaper version of the dual band.
As much as I hate to admit it but iv started using it again to finish the pretiege challange, yes its a good optic especially on LMGs but I wouldn't really say its OP since you do still have to aim to actually hit anyone.
