3D printing just got way more awesome. Inalienable rights means you have the right to keep and bare arms regardless of what the law or anyone else says. With 3D printing it is made easy. You can buy a 3D printer off of amazon and download plans for what firearm you like and get to printing.
Oh and don’t register your firearm or at least not all of them. No one has the right to put your property on a register as the police will come to confiscate it the moment the politicians tell them to. They are trained to follow orders not to do the right thing.
