From Atlas Society:
The Bill of Rights was added to the Constitution to explicitly restrain the federal government from infringing on specific rights considered to be most sacrosanct. It was not created to define the proper use or regulation of any select or limited list of physical goods, but to protect principles or rights key to man's existence, success, and freedom. In the case of the Second Amendment, our right to defend our lives and our property is enshrined.
Stating that “the right of the people to keep and bear Arms, shall not be infringed” cannot be construed to mean “citizens may bear arms unless those guns become too effective at achieving the purposes for which they are created, in which case the only arms allowed are those listed in article ‘never written’, section ‘make it up as you go along’.”
