well you have a pistol, and the AR could be used at quit a distance if your good with it.
no weapon is useless, sure the BR is better than the AR and magnum in nearly every way, but they're guns and they deal damage at all ranges if you don't need auto aim to land long range shots.
not that I like AR starts but really it's not like any changes are going to be made in this game.
