Regarding the drop-in sears to convert the guns, Gibbons said the technology exists to mass-produce them cheaply and easily. He said that with a $150 3D printer and $5 worth of filament, "you can pop one of these out every five minutes."
If the danger is so great, Rudofsky asked Gibbons from the bench, why did the investigation -- which lasted several months -- take so long while Rockefeller was left unaware and continuing to distribute both the devices and the converted weapons?
"I'm trying to reconcile how dangerous this conduct is with how long this investigation took and how long you let him stay in business," the judge said.
Gibbons explained that, because Rockefeller was working at the time for a federally licensed firearms dealer, it took time to sort out which activities were illegal and who all was involved.
