The printed guns have no metal parts huh? What about the firing pin and ammunition?

A gun rights group in Sacramento is generating controversy by creating a website with detailed instructions on how to construct a 3D-printed gun made of plastic.

“They are publicly available and people can download them if they wish,” said Craig DeLuz, a spokesperson for the Firearms Policy Coalition.

“It’s as simple as a site can be,” DeLuz said.

The step-by-step instructions for printing the plastic guns allows anyone with time, money and the initiative to do it themselves at home.

DeLuz said he believes the government has no right to restrict what you can say before it's even said.

“This case right here is largely about freedom of speech,” DeLuz said. “Being able to put information out there, and simply, the state does not have the right to infringe on speech.”

A federal judge on Tuesday temporarily blocked a government settlement that would have allowed a gun rights group in Texas to post 3D-printed gun blueprints online.

But, the ruling doesn’t prohibit other groups from showing people how to make the 3D-printed guns, which have no serial numbers and can’t be traced. The printed guns have no metal parts, so there’s nothing to trigger an alarm through a metal detector.
