I voted change it, only because it actually describes the rifles better. I mean, I have a lot of black rifles that are not "Black Rifles" and vice versa, so modern sporting rifles covers that. I don't consider it bowing down to the anti's as appose to accurately describing are non assault weapons.
I hate it when someone asks a gun owner, "why do you need an assault weapon/black rifle", and they respond. I just reply, "I don't have an assault weapon", or "many of my rifles are black, here, check out this painted Cooey".
