Just to point out one thing about your "descriptor paragraph", the ban actually prohibits guns with 2 or more of those "options", not limits them to having only two of them, they can only have one.
Actually its two, for example the current production Ar-15 style guns have both a detachable magazine which is one option and a pistol grip which is two. Trust me when I say its two.
but come monday it wont make damn difference
