Here's my prediction. No money bet on this, but I'm guessing three things will happen (or "they" will attempt to make them happen) which the administration will go along with:
1) Bump stocks etc. gone. I noticed the Trump administration has been careful to word it as "banning devices that turn LEGAL guns into illegal guns. My belief is that they are doing that to protect ARs, etc. as legal items. As I mentioned earlier, throwing the grabbers a "gimme" while trying to protect the rifles themselves.
2) Purchase age for everything changed to 21. How much this affects rights I suppose is linked to the exact language, such as "purchase" vs "possess".
3) "Fix" background checks. I have no idea what this means, but it's being thrown around a lot from somehow making them more "thorough" (whatever that means) to including "enhancements" for investigation of mental conditions. I would not be surprised, however, to see some additional "checks" (perhaps only annoying, perhaps bad) added to NICS with the support of the administration.
