They also would stop anything that will keep things for being sold for guns. Prime example is silencers, why would anyone outside SPECOPS need silencers. I hear it will help with hunting, but the elk, deer, and antelope will still move when they hear the bullet fly by them. Then you'd have the safety issue of other hunters in the area not hearing a shot from a silenced weapon. The NRA is backing to see if a bump stock should be legal is because of all the outcry about it. Even if there is a ban on bump stocks, I believe it won't happen, there are other ways to make a gun an automatic. Gun control for the most part is a joke.
