A judge sentenced T.I. to one year and a day behind bars on federal weapons charges on Friday.

The 28-year-old rapper, whose real name is Clifford Harris, wore a dark gray suit and black dress shirt and tie for sentencing. T.I. plead guilty last March after he was arrested on October 13, 2007 for attempting to buy unregistered machine guns and silencers. He had faced a maximum of 10 years in prison and a $250,000 fine for each count, until he cut a deal and pleaded guilty last March to the federal weapons charge.

T.I. has already has completed about 1,000 hours of court-ordered community service warning youths about the dangers of guns, drugs, violence. He still needs to complete 470 additional hours.

“Today I would like to say thank you to some, and apologize to all,” the rapper told U.S. District Judge Charles Pannell Jr. at this morning’s session.

“Everything I learned was through trial and error….“I’ve learned lessons in my life to put in my music so people won’t make the same mistakes as I.”

The Grammy Award winner will have between 30 and 60 days to report to prison.
