The bill modernizes the definition and regulation of undetectable firearms under 18 U.S.C. § 922 by updating the criteria and definitions related to firearm components and detection.

  • 18 U.S.C. § 922(p)(1)(A)

    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 → all parts other than major components, does not contain detectable material

    This change simplifies the definition of undetectable firearms by focusing on all parts excluding major components.

  • 18 U.S.C. § 922(p)(1)(B)

    when subjected to inspection by the types of x-ray machines commonly used at airports, does not generate → if subjected to inspection by the types of detection devices commonly used at airports for security screening, would not generate

    This modifies the language regarding how firearms are assessed for detectability by airport security equipment.

  • 18 U.S.C. § 922(p)(2)(B)

    subparagraph (B) and inserting the following: → the term `major component', with respect to a firearm-- (i) means the slide or cylinder, or the frame or receiver of the firearm; and (ii) in the case of a rifle or shotgun, includes the barrel of the firearm;

    This clarifies the definition of 'major component' for firearms, specifying the parts included.

  • 18 U.S.C. § 922(p)(2)(C)

    subparagraph (C) and the proviso that follows and inserting the following: → the term `detectable material' means material that produces a magnetic field that is equivalent in strength to the magnetic field produced by 3.7 ounces of 17-4 PH stainless steel.

    This establishes a specific standard for what constitutes detectable material in firearms.

  • 18 U.S.C. § 922(p)(3)

    the second sentence

    This removes an existing sentence that may have contained outdated language regarding prototypes.

  • 18 U.S.C. § 922(p)(5)

    shall not apply to any firearm which and all that follows → shall not apply to-- (A) any firearm received by, in the possession of, or under the control of the United States; or (B) the manufacture, importation, possession, transfer, receipt, shipment, or delivery of a firearm by a licensed manufacturer or licensed importer pursuant to an existing contract with the United States.

    This change clarifies that certain firearms are exempt from the undetectable firearms prohibition under specified conditions.
