Gucci Mane Facing a Stretch In The PEN!

Gucci Mane is facing some serious time behind bars after pleading guilty to firearm possession this morning in Atlanta.

According to TMZ, since Gucci is already a convicted felon, he faces a maximum of 10 years behind bars. But under a plea deal, he's expected to serve 39 months, which will have him released sometime in 2016.

Gucci, who has been behind bars since September, will officially be sentenced in July. He was arrested in September when cops found him with a handgun and a small amount of pot.
