Now you've proved you and your little liberal arts degree don't know much. Especially about gun law's. You can make anything you want, they even sell kits for people who don't know much. You could even build a machine gun up to a few years back, you just were required to register it. There would be no custom guns at all if it were illegal to build them. So when did it become illegal to build a custom target rifle.
Second I never said I had a doctorate, you made the meathead statement that you were better educated. And to have been so you would have needed the doctorate.
