A Dawsonville man and Wingman Motorcycle Club member was found guilty in Gainesville's federal court on weapons charges in September.
James "Bobby" McGlothlin, 48, was indicted on Aug. 14, 2012, on charges of selling a firearm to a person knowing that the individual was a felon.
By federal statute, it is illegal to sell guns to addicts, felons or fugitives.
McGlothlin was found guilty by a jury in one hour on Sept. 25, federal authorities said.
Sentencing by U.S. District Court Judge Richard Story has not been scheduled.
The case was the first to see a jury in Northeast Georgia after an uncover federal investigation netted 23 arrests, most with ties to the Outlaw Motorcycle Club and affiliate clubs in Georgia, authorities said.
Eight defendants are set to see a trial in Gainesville on conspiracy and firearm charges.
Davey Honeycutt, Brandon Musser, Reynol Castrejon, Phillip Honeycutt, Thomas Coley, Josue Guerrero, David Rizo-Troncoso and Jessi Castillo are all charged with drug and weapon conspiracy charges in USA v. Honeycutt et al.
A pretrial conference is scheduled for Oct. 28 in Magistrate Court.
