As expected, T.I. was officially sentenced to a year and a day in prison on Friday (March 27) for federal weapons violations, stemming from a 2007 arrest by ATF agents in Atlanta.

The rapper (real name: Clifford Harris) originally faced up to 20 years in prison, but pleaded guilty last year as part of a plea agreement in which he was perform 1,500 hours of community service and a reduced sentence.

Since then, he's been running around the country speaking to schools and youth groups about anti-crime, some of which was documented for MTV's reality show "T.I.'s Road to Redemption."

T.I. could also see his sentence reduced, by as much as 15%, with good behavior.

According to Reuters, U.S. attorney for the Northern District of Georgia David Nahmias, said in a statement that T.I.'s community service exceeded prosecutors' expectations and that "there is still more to come when he gets out of prison."

The rapper is expected to turn himself in to begin serving his sentence sometime before, or on May 19th.

T.I. was arrested in October 2007, just hours before he was slated to appear at the second annual BET Hip-Hop Awards in Atlanta. Federal agents set up a sting, through the rapper's bodyguard, to catch him in the act of trying to purchase machine guns and silencers.

His bodyguard claimed the rapper gave him cash to purchase guns in the past, because T.I., as a convicted felon, was not able to legally possess firearms.

After his arrest, he posted $3 million bail.
