The next step wont be selling an ar-15 upper and lower its going to be a desktop machine that you put a piece of billet into and a spoon and fork or maybe instead with the right open source software an ar-15 upper and lower comes out. I think thats very doable for about 1200 dollars. All any of the things they are doing will do is encourage people to make real untraceable guns and drill 3rd holes. They can beat around the bush but we know eventually they are going to try a grab. Gun culture needs to shift away from thinking they are going to be allowed to exist and embrace rebellion across all facets of the culture.
