Young Buck to Begin 18-Month Prison Sentence

Rapper Young Buck is back in prison, where he will be until late 2013 at the earliest. He's serving an 18-month sentence for gun possession.

Yesterday, 31-year-old Buck checked into Yazoo City Medium Security Federal Prison in Southern Mississippi to begin serving hard time.

Federal agents recovered multiple guns in Buck's home during a 2010 raid.

At the time of that arrest, the G-Unit member was already prohibited from possessing any firearms because he was a convicted felon ...  not good.
