Dude better watch out!

Migos' Offset was arrested Saturday for gun possession in Atlanta after being pulled over for window tinting that was too dark. If you're gonna black out the windows, better not make an illegal lane change and have a gun and weed inside the car!

The 26-year-old is a convicted felon and on probation and he just became a four-time dad, welcoming the birth of daughter Kulture Kiari with wife Cardi B on July 10.
