Undetectable Firearms Modernization Act

To reauthorize the ban on undetectable firearms, and to extend the ban to undetectable firearm receivers and undetectable ammunition magazines. 1. Short title This Act may be cited as the Undetectable Firearms Modernization Act 2. 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 3D printers (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. 3. Reauthorization of ban on undetectable firearms Section 2(f)(2) of the Undetectable Firearms Act of 1988 ( 18 U.S.C. 922 25 35 4. Ban extended to undetectable firearm receivers made by individuals Section 922(p) of title 18, United States Code, is amended— (1) in paragraph (1)— (A) in the matter preceding subparagraph (A), by striking receive any firearm— receive— (B) by striking subparagraphs (A) and (B) and inserting the following: (A) any firearm— (i) that, after removal of grips, stocks, and magazines, is not as detectable as the Security Exemplar, by walk-through metal detectors calibrated and operated to detect the Security Exemplar; or (ii) any major component of which, when subjected to inspection by the types of x-ray machines commonly used at airports, does not generate an image that accurately depicts the shape of the component. Barium sulfate or other compounds may be used in the fabrication of the component; or (B) any receiver for a rifle, or receiver for a handgun, manufactured by a person who is not a licensed manufacturer— (i) that is not as detectable as the Receiver Security Exemplar for a rifle or for a handgun, as the case may be, by walk-through metal detectors calibrated and operated to detect that Receiver Security Exemplar; or (ii) which, when subjected to inspection by the types of x-ray machines commonly used at airports, does not generate an image that accurately depicts the shape of the receiver. Barium sulfate or other compounds may be used in the fabrication of the receiver. ; (2) in paragraph (2)— (A) by striking and (B) by striking the period at the end of subparagraph (C) and inserting ; and (C) by adding at the end the following: (D) the term Receiver Security Exemplar (i) constructed of, during the 12-month period beginning on the date of the enactment of this subparagraph, 3.7 ounces of material type 17–4 PH stainless steel in a shape resembling the lower receiver for a rifle or for a handgun, as the case may be; and (ii) suitable for testing and calibrating metal detectors: Provided, however, That at the close of such 12-month period, and at appropriate times thereafter the Attorney General shall promulgate regulations to permit the manufacture, importation, sale, shipment, delivery, possession, transfer, or receipt of receivers for a rifle or receivers for a handgun, that were previously prohibited under this subparagraph that are as detectable as the Receiver Security Exemplar ; (3) in paragraph (3)— (A) by inserting or receiver firearm (B) by inserting or receivers firearms (4) in each of paragraphs (4) through (6), by inserting or receiver firearm 5. Ban extended to undetectable ammunition magazines made by individuals Section 922(p) (1) in paragraph (1)— (A) by striking or (B) by striking the period at the end of subparagraph (B) and inserting ; or (C) by adding at the end the following: (C) any ammunition magazine, manufactured by a person who is not a licensed manufacturer— (i) that, after removal of the spring and follower, is not as detectable as the Magazine Security Exemplar, by walk-through metal detectors calibrated and operated to detect the Magazine Security Exemplar; or (ii) which, when subjected to inspection by the types of x-ray machines commonly used at airports, does not generate an image that accurately depicts the shape of the magazine. ; (2) in paragraph (2)— (A) by striking and (B) by striking the period at the end of subparagraph (D) and inserting ; and (C) by adding at the end the following: (E) the term Magazine Security Exemplar (i) constructed of, during the 12-month period beginning on the date of the enactment of this subparagraph, 1 ounce of material type 17–4 PH stainless steel in a shape resembling an ammunition magazine; and (ii) suitable for testing and calibrating metal detectors: Provided, however, That at the close of such 12-month period, and at appropriate times thereafter the Attorney General shall promulgate regulations to permit the manufacture, importation, sale, shipment, delivery, possession, transfer, or receipt of ammunition magazines previously prohibited under this subparagraph that are as detectable as a Magazine Security Exemplar ; (3) in paragraph (3)— (A) by striking firearm or receiver firearm, receiver, or ammunition magazine (B) by striking firearms or receivers firearms, receivers, or ammunition magazines (4) in each of paragraphs (4) through (6), by striking firearm or receiver firearm, receiver, or ammunition magazine

Summary: Undetectable Firearms Modernization Act - Amends the Undetectable Firearms Act of 1988 to: (1) delay the repeal date for 10 years; and (2) extend coverage of, and exemptions under, the Act to undetectable firearm receivers and ammunition magazines. Prohibits the manufacture, importation, sale, shipment, delivery, possession, transfer, or receipt of any receiver for a rifle or handgun, or of any ammunition magazine, that: (1) is manufactured by a person who is not a licensed manufacturer; (2) is not as detectable as the Receiver Security Exemplar or the Magazine Security Exemplar by walk-through metal detectors; or (3) does not generate an image that accurately depicts the shape of a receiver or a magazine when subjected to inspection by airport x-ray machines. Allows barium sulfate or other compounds to be used in the fabrication of a firearm receiver. Defines a "Receiver Security Exemplar" and a "Magazine Security Exemplar" as objects fabricated at the direction of the Attorney General that are: (1) constructed, respectively, of 3.7 ounces of material type 17-4 PH stainless steel in a shape resembling the lower receiver for a rifle or handgun or of 1 ounce of material type 17-4 PH stainless steel in a shape resembling an ammunition magazine; and (2) suitable for testing and calibrating metal detectors. Directs the Attorney General to promulgate regulations to permit receivers or magazines that were previously prohibited but that become as detectable as the respective Exemplar in view of advances in weapons detection technology.
