Man sentenced to 14 years for 3D printing machine guns in Mississippi

A Mississippi man with a prior felony conviction has been sentenced to 14 years in federal prison for illegally manufacturing machine guns using 3D printers. Kent Edward Newhouse used 3D printers to manufacture a firearms component called an "auto sear," which turns a semi-automatic firearm into a fully automatic machine gun. Auto sears have been turning up more often in places like Louisville and Washington D.C. Congressional Democrats have reintroduced legislation to prevent the importation and trafficking of conversion devices such as auto sears.
