,judiciary ,a ,,bill ,to reauthorize the ban on undetectable firearms1 and to extend the ban to undetectable firearm receivers and undetectable ammunition magazines4 #a4 ,short title ,this ,act may be cited as the ,undetectable ,firearms ,modernization ,act4 #b4 ,findings ,the ,congress finds that-- 7#a7 according to data from the ,federal ,bureau of ,investigation1 #h1ehc of the #ab1ffd murders in the ,united ,states in #bjaa were committed using a firearm1 and more than #eg percent of the murders that occurred in ,new ,york ,state were perpetrated with a firearm2 7#b7 the ability to produce a receiver for a firearm in the home would circumvent a number of laws1 because the receiver is the component of the firearm that bears its serial number1 as required by regulations2 7#c7 digital manufacturing technologies1 including but not limited to computer numerical control mills 7,,cnc mills71 #c-;dimensional printers 7#c;,d printers71 and laser cutting machines1 are quickly advancing to a point where it will soon be possible to fabricate fully operational firearm components2 and 7#d7 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 detectors1 and may not present an accurate image on an x-ray4 #c4 ,reauthorization of
