Short title

This Act may be cited as the

Undetectable Firearms Modernization Act

Findings

The Congress finds that— (1)according to data from the Federal Bureau of Investigation, 8,583 of the 12,664 murders in the United States in 2011 were committed using a firearm, and more than 57 percent of the murders that occurred in New York State were perpetrated with a firearm; (2)the ability to produce a receiver for a firearm in the home would circumvent a number of laws, because the receiver is the component of the firearm that bears its serial number, as required by regulations; (3)digital manufacturing technologies, including but not limited to computer numerical control mills (CNC mills), 3-dimensional printers (3D printers), and laser cutting machines, are quickly advancing to a point where it will soon be possible to fabricate fully operational firearm components; and (4)some commercially available products that utilize digital manufacturing technologies to manufacture objects are able to manufacture these objects using materials that are unable to be detected by traditional metal detectors, and may not present an accurate image on an x-ray.

Reauthorization of ban on undetectable firearms

Section 2(f)(2) of the Undetectable Firearms Act of 1988 (18 U.S.C. 922 note) is amended by striking 25 and inserting 35.
