Indeed, this has gone from being a long shot in the dark to being a real possibility. The constitution has unfortunately been open to interpretation and the second amendment doesn't say anything about regulation. The NRA has done a wonderful job of looking out for our rights, but as we have seen before things can quickly change. Half of your weapons collection (including accessories) could be deemed illegal overnight.
We have seen the administration sidestep other checks and balances in route to stripping us of our constitutional rights. Usually it comes under the pretense of protection, like the Patriot Act for example. They will sell this thing as something entirely different (human rights), but will simultaneously use it to tighten restrictions, keep track of sales and transfers, and limit your second amendment rights. We have to keep an eye on this.
My theory on the general public is that they're like mushrooms, they thrive when you feed em $hit and keep em in the dark.
