Trump's trio and really all the Right leaning justices on SCOTUS are terrified of the court being packed. I would not fool myself into believing AWB, mag capacities, and other "nuts and bolts" gun laws are going to even be heard by SCOTUS, let alone struck down. Further, the Supreme Court really has no enforcement mechanism as it's the executive branch that is given powers of enforcing laws and upholding the Constitution, thus an anti gun state can easily ignore the rulings and nothing will happen because a Democrat President now is an anti-Constitutionalist while a Republican President will be advised against using the power of the Federal gov't to enforce a pro gun SCOTUS ruling do to fears they'll look mean and be called a dictator for sending in National Guard against a state's wishes.
This is why any sort of pro gun ruling from SCOTUS from now until whenever our side that's full of lazy, cucked Christian cowards decides enough is enough and revolts, is going to be as narrow as possible. Just like how our gun rights were slowly chipped away starting with the NFA Act, the Supreme Court has to slowly chip away with the undoing of it all or else the Left is going to ignore it and really turn the country into a lawless nation on the brink of civil war.
