Gun control proponents and state officials are racing the clock to try to block blueprints to make guns from 3-D printers from going online Wednesday.
The varied efforts, in courthouses and legislatures, are aimed at Defense Distributed, a Texas-based nonprofit organization that won permission last month from the State Department to post schematics for homemade firearms. The largely plastic guns would be invisible to background checks and untraceable by law enforcement.
