New York changes gun buyback after seller gets $21,000 for 3D-printed parts

Participant used a 3D printer to make firearm parts in bulk that he then exchanged for gift cards

The attorney general of New York has changed the rules of a state gun buyback program, after a participant exploited the system by using a 3D printer to make firearm parts in bulk that he then exchanged for $21,000 in gift cards.

The seller, who identified himself by a pseudonym, said he traveled from West Virginia to a gun buyback on 27 August in Utica, New York, to take advantage of a loophole in the program - and to demonstrate that buybacks are futile in an era of printable weapons.
