Or you could just buy a bullpup designed rifle and have a gun just as short or shorter without all the paperwork and hassle and there isn't the velocity loss of a SBR. But a short AR would be cool.

"Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." C.S. Lewis
