I personally like the idea. I agree that sniper rifles should be RARE but I think it's nice to have the chance to get one. It all depends on the Time-To-Kill. If this is like King of the Kill, maybe they are a bit too overpowered. If this is like Insurgency where one bullet from almost any gun can kill you, then I think a scoped rifle is fair game. But even if snipers are ruled out, I agree that a single fire bolt action rifle would be a good addition. Much higher risk reward.
