Agents from the federal Bureau of Alcohol, Tobacco, Firearms, and Explosives, or ATF, have begun confiscating gun parts known as drop-in auto sears, or DIAS. A DIAS is a simple toggle device which, when installed in an AR-type rifle, along with several other critical fire-control parts, can convert a semi-auto AR into a full-auto assault rifle. The devices were originally unregulated, but in 1981 ATF declared them to be machine guns if possessed in conjunction with the other parts needed to make a conversion, but the agency made their new determination apply only to DIASes manufactured after Nov. 1, 1981. Now ATF is apparently using the records of a man who openly sold the devices for decades to track down purchasers and take their property as contraband – with the real possibility of then prosecuting those people.
