Why do you need anything more than a revolver or a single-shot rifle or
shotgun available to everyone?
I don't need anything regarding a firearm
I can simply because I can.
And "everyone" doesn't have to or want to own a firearm.
That is the beauty of the right guarenteed me and every other American citizen by the founding document of our nation. The federal government does not have the right or, as a practical matter, the ability to disarm me and all the other tens, if not a hundred or more, million of legal gun owners.
It is just one reason why there are some who want to do just that. They don't like the people having power that is not doled out by a government.
Criminals will get guns. Look at those nations where there is gun confiscation and/or extremely strict control. The crooks still manage to get them and use them illegally. Only those trying to obey the law get punished.
Seems a bit off to me.
