The 29-year-old performer, whose real name is Clifford Harris Jr., pleaded guilty to a federal weapons charge in connection with a 2007 incident in which he used a bodyguard to attempt to buy unregistered machine guns and silencers from an undercover government agent.
The hip-hop artist had been staying at the Dismas Charities Atlanta West since he was released last year from Forrest City Federal Correctional Complex in Arkansas where he served seven months.
E! News said Harris still must observe a nightly curfew and complete 400 hours of community service as part of his sentence.
