In honor of the Feds trying to block the spread of the Defense Distributed Liberator gun plans, here they are. If you are an American you have to right to free speech and the right to manufacture and posess firearms. You can also mill your own metal AR-15 lower which does not need to be registered with anyone, and buy the rest online (check your local laws and regulations).

The Feds can stop Defense Distributed but they can't stop citizens from utilizing their constitutionally protected liberties.
