Eventually, if the tide truly turns to gun control, all semis will be banned as will lever action guns. 5 shot bolt action guns will be allowed for Uncle Dick in his deer stand bu they may have to be stored at home under lock and key or at the gun club or similar facility.
Scalia's prose in Heller will be used to support such rules and similar prose in Buren.
It might take a few years for the antis to filter through all the dodges and silliness to take out the Mini-14s and PCCs without threaded barrels, the bizarre locked mag ARs that you feed through the ejection port with a Rube Goldberg speed loader, etc. but it will come in time.
But wait, Scotus might actually say something definitive against the bans and think through the counter punches, although it is claimed they are not allowed to do that.
