A Texas man has been sentenced to eight years in federal prison after police found him in the woods with a partially 3-D printed AR-15 rifle and a list of federal lawmakers' addresses in his backpack. Eric McGinnis was convicted last summer of possessing an unregistered short-barreled rifle. He also was found guilty of unlawfully possessing ammunition while subject to an active protective order that had been issued because of a 2015 altercation with a girlfriend. McGinnis, who sentenced Wednesday, tried to buy a semiautomatic rifle in 2016 but was turned away because of the protective order, prosecutors said. According to the Dallas Morning News, McGinnis instead used a 3-D printer to create the firing mechanism for an AR-15. Investigators said McGinnis admitted in a jailhouse phone call to a family member that he'd printed part of the gun.
