Reply #55: Yes, you're right.. "the Constitution isn't arbitrary or subject to the vagaries of fashion"

So laws that ban a 'fashion' of rifle are unconstitutional, right?

If you hadn't been told why these rifles with features are actually better (*clue phone* nothing to do with 'fashion') I'd understand your confusion.

I'd tell you that a) many of these rifles are lighter, b) less prone to dings and scratches, c) have less recoil (the 'kick' described by Newton's Third Law), d) less prone to jam or wear (especially true of the AK pattern rifles), and e) in many cases, are able to be reconfigured to meet different needs (more mounting options for things like lights, optics, bipods, grips; as well as the ability to accept multiple calibers in the case of something like an AR-15.)
