The one side of the story: a crime scene evidence collector finds a shell casing at the scene of a crime. They photograph it, bag it, and turn it over to the crime lab. Upon examination, they find a microscopic imprint on the case head that belongs to a Value Arms .223 serial number 69000. After a search with the manufacturer, investigators find the distributor that sold it, who contacts the gunshop it was sent to. A phone call and fax to the gun shop has a return fax of an ATF form 4473 with whom they sold the firearm to. Science fiction? CSI on steroids? No its micro stamping and it could possibly be coming to a firearm near you.
