Police spokesman Cpl. John Barnett says troopers pulled over a car over north of Millsboro after it passed another car near Georgetown and showed a gun out the window.
The car was pulled over on Route 113 and two occupants were charged.
Twenty-year-old Stefone Dukes of Lincoln and 18-year-old Michael Pritchett of Lewes are charged with aggravated menacing and conspiracy.
Police say the gun turned out to be a BB gun that had been painted black to resemble a real handgun.
