(Eugene, OR) -- A Eugene man faces charges for allegedly owning homemade machine guns. Federal prosecutors say last August a search of 35-year-old Joshua Lampe's home found dozens of guns, ammunition, scopes, laser sights, and tactical gear. Four months later, another search found more guns, including two pistols that were converted into fully automatic firearms. Lampe is also accused of using a 3D printer to make switches that turn semi-automatic guns into fully automatic weapons. Lampe is scheduled for trial in September.
