The files you need to make your own gun can now be legally shared online

A decision from the US Department of Justice allows the online distribution of computer-designed gun models. But… Makers will need to have a working knowledge of gun mechanics, 3-D printing, and manufacturing technologies like CNCs to construct a weapon from these files. While Wilson has lowered some of the barriers to create undocumented weapons in your garage, home-based setups will have to advance mightily before your neighbor will be able to make their own  AR-15.
