Ah, O.K. Diater. They are not only active at night and they aren't fast if they are standing still, and something more "tricky" isn't needed, and lots of hunters are capable of killing them without a scope, some even choose to use archery gear from time to time. Although it is tough to argue about different prices on scopes and sure enough, it is possible to grab something at a "really decent" price if one shops around.
You best stick to you AR15.
