Judge Kavanaugh has written in an opinion that you can no more ban certain classes of commonly owned firearms than you can ban certain classes of speech.
The McDonald case makes 2A binding upon the states/cities.
I suspect that we haven't had any Supreme Court 2A cases in the past few years because no faction within the Court was sure of being able to muster a majority. With Kavanaugh and one more appointment, I think we may see the door open to many more cases. Pres. Trump's list of Supreme Court candidates comes straight from the Federalist Society, a legal group dedicated to principles that most of us here hold dear. We are going to keep on liking his appointments, a lot.
You can really wreck your reputation as a forecaster by trying to predict what the Supreme Court will do, but based on the judicial writings I have read, here's what I expect over the next 10-15 years:
Invalidation of all outright bans on semiautomatic rifles, or on just AR15s.
Invalidation of all bans on magazines that hold more than some arbitrary number of cartridges.
Verification that there is a right to keep and bear arms that extends beyond the home (already implicit in Heller). This will strike down the California scheme of banning open carry and almost not allowing concealed carry. It will also strike down schemes in some jurisdictions designed to make it as difficult and expensive as possible to keep and bear firearms.
Establishment of the doctrine that in order to restrict firearms, the state/city must show that the restriction is long established and must be based on solid evidence of overriding state interest.
As I said, I may be wrong. But this is what the tea leaves tell me. None of the constitutional guarantees are iron-clad. They simply mean that if you decide to challenge an unconstitutional law, the table is rigged in your favor.
