Illinois is banning ghost guns. What is a ghost gun?

It’s a firearm that can be made at home, with individual parts and doesn’t include a serial number to track who bought it or sold it. Democrat Governor JB Pritzker says the problem of ghost guns is growing across the nation. And Illinois State Police Director Brendan Kelly says they are becoming the first choice of criminals.

The bill signed today also requires anyone with a gun without a serial number to get it numbered and registered.
