A bill has been introduced by a Florida congressman to bring all semiautomatic rifles that can accept detachable magazines under the NFA. https://www.congress.gov/bill/116th-congress/house-bill/1263/titles?r=13&s=1 Few details. This isn't going anywhere. Sen. Feinstein proposed something like this in 2013 (after Sandy Hook) but relented when it became obvious the plan was unworkable. Still, this is worth studying (when and if details are released) for two reasons: first, it provides a window into the thinking of the antigunners, regarding an "assault weapons ban." Clearly, they are worried about issues such as grandfathering, confiscation, and the compensation that would go along with that. Bringing the banned items under the NFA would neatly solve all these problems for them. Secondly, the pro-gun side might stand to gain something in this process. Adding multiple millions of guns to the NFA registry would change it completely. For one thing, it would have to be automated and streamlined. And if semiautos are treated as machine guns, there would be no legal difference between them. That would have some interesting implications. In addition, in amending the NFA, things like suppressors and short-barreled weapons could easily be removed since those provisions would be redundant.
