With the right software and the right machine, individuals can manufacture their own guns. From StockBoardAsset.com:
The story starts with Cody Wilson, an American crypto-anarchist, free market anarchist, and gun-right activist. He is the founder of Defense Distributed, a non-profit organization that develops and publishes open source gun designs.
The about section on Defense Distributed describes the company as an ‘anti-monopolist digital publishing’.
Back in 2013, Defense Distributed gained international attention after it published the world’s first fully 3D-printed gun called the Liberator. Almost immediately, the Statement Department under the Obama administration demanded Mr. Wilson takedown the 3D-printable gun files for possible export control violations. In the first two days, downloads for the 3D-printable gun exceeded 100,000.
Wilson argued that he’s legally protected, and says Defense Distributed “is excluded from the ITAR regulations under an exemption for non-profit public domain releases of technical files designed to create a safe harbor for research and other public interest activities”.
Mr. Wilson eventually had to remove the Liberator files from the internet, due to State Department pressure.
Jumping to 2014, Mr. Wilson received the title as ‘Ghost Gunner’ and was described as a gun manufacture by some for creating AR-15 frames without serial numbers. Defense Distributed offered the internet a package including a CNC milling machine that can turn an aluminum block into an AR-15 lower receiver, the components regulated by state and federal authorities. The machine called ‘Ghost Gunner 2’ (3D-printer) and 80% AR-15 lower receivers are still being sold on Defense Distributed’s website.
