B.G., born Christopher Dorsey, is facing up to 10 years in prison over an incident in November of 2009.
The 30-year-old rapper and two other men were arrested when police stopped their car and found three guns, loaded magazines and extended clips.
To make matters worse, two of the three guns police found were reported stolen.
According to the charges, B.G. conspired with two other men to get a man named Demounde Pollard to claim ownership of the guns.
Pollard, 19, is accused of signing a false affidavit stating that B.G. did not possess the guns.
Pollard and another man named Jerod Fedison have already pleaded guilty to the related charges.
