Rick Ross’ Georgia estate is crawling with sheriff’s deputies after a man allegedly armed with a gun led cops on a wild chase … and now there’s a hunt for the weapon.

Law enforcement sources tell TMZ … Clayton County Sheriffs started a vehicle pursuit with a driver Tuesday after they got a call for a male with a gun. We’re told the pursuit ended when the driver crashed near Ross’ property and took off.
