On Wednesday, Council Members Helen Rosenthal (D-Manhattan) and I. Daneek Miller (D-Queens) introduced two pieces of legislation, one of which would make it illegal to possess or dispose of unfinished receivers, i.e., the gun frames to which the other components attach. Those pieces may be available online, or even 3-D printed; in any case, the frames lack serial numbers, meaning law enforcement can’t easily track them and owners can avoid permitting and background check requirements.

The proposed bill makes possession of an unfinished receiver or frame punishable by a $1,000 fine or a year in prison.
