To amend chapter 44 of title 18, United States Code, to ensure that all 
            firearms are traceable, and for other purposes.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Untraceable Firearms Act of 2020''.

SEC. 2. SENSE OF CONGRESS.

    It is the sense of Congress that--
            (1) without the enactment of this Act, the Bureau of 
        Alcohol, Tobacco, Firearms and Explosives has the authority to 
        regulate ghost guns (as defined in section 921(a) of title 18, 
        United States Code, as amended by section 3 of this Act) and 
        unfinished frames and receivers; and
            (2) the purpose of this Act is to clarify and strengthen 
        such authority.

SEC. 3. REQUIREMENT THAT ALL FIREARMS BE TRACEABLE.

    (a) Definitions.--Section 921(a) of title 18, United States Code, 
is amended--
            (1) in paragraph (3), by striking ``or (D) any destructive 
        device'' and inserting ``; (D) any destructive device; or (E) 
        any combination of parts designed or intended for use in 
        converting any device into a firearm and from which a firearm 
        may be readily assembled'';
            (2) in paragraph (10), by adding at the end the following: 
        ``The term `manufacturing firearms' shall include assembling a 
        functional firearm from a frame or receiver or molding, 
        machining, or 3D printing a frame or receiver, and shall not 
        include making or fitting special barrels, stocks, or trigger 
        mechanisms to firearms.'';
            (3) by inserting after paragraph (29) the following:
    ``(30) The term `frame or receiver'--
            ``(A) means the part of a firearm that provides or is 
        intended to provide the housing for the trigger group, 
        regardless of the stage of manufacture;
            ``(B) includes a frame or lower receiver, including blank, 
        casting, or machined body, that requires modification, 
        including machining, drilling, filing or molding, to be used as 
        part of a functional firearm, and which is designed and 
        intended to be used in the assembly of a functional firearm; 
        and
            ``(C) does not include a piece of material that has had--
                    ``(i) its size or external shape altered solely to 
                facilitate transportation or storage; or
                    ``(ii) solely its chemical composition altered.''; 
                and
            (4) by adding at the end the following:
    ``(36) The term `ghost gun'--
            ``(A) means a firearm, including a frame or receiver, that 
        lacks a unique serial number engraved or cast on the frame or 
        receiver by a licensed manufacturer or importer in accordance 
        with this chapter; and
            ``(B) does not include a firearm that has been rendered 
        permanently inoperable.''.
    (b) Prohibition; Requirements.--Section 922 of title 18, United 
States Code, is amended by adding at the end the following:
    ``(aa)(1) The Congress finds and declares the following:
            ``(A) Firearms tracing is the systematic tracking of the 
        movement of a firearm recovered by law enforcement officials 
        from the first sale of a firearm by the manufacturer or 
        importer through the distribution chain (including the 
        wholesaler and retailer) to the first retail purchaser.
            ``(B) Law enforcement agencies across the country work with 
        the Bureau of Alcohol, Tobacco, Firearms and Explosives to 
        trace firearms and thereby obtain investigative leads in the 
        fight against violent crime and terrorism.
            ``(C) The ability of law enforcement agencies to trace a 
        firearm is dependent on the serial number or other marks on the 
        firearm that identify the manufacturer or importer who 
        manufactured or imported the firearm and that are unique to the 
        firearm.
            ``(D) Interstate gun trafficking interferes with lawful 
        commerce in firearms and significantly contributes to gun 
        crime. Of the 254,700 firearms traced by the Bureau of Alcohol, 
        Tobacco, Firearms and Explosives in 2018, 71,910 of those 
        firearms were originally sold by a licensed firearms dealer in 
        a State other than the State where the firearms were recovered. 
        These guns made up 28.2 percent of all firearm recoveries in 
        2018.
            ``(E) Even before the sale of a firearm, the gun, its 
        component parts, and the raw materials from which they are made 
        have considerably moved in interstate commerce.
            ``(F) If unserialized and untraceable firearms may be 
        constructed and transported freely from State to State, 
        ordinary citizens and foreign visitors may fear to travel to or 
        through certain parts of the country due to concern about 
        violent crime and gun violence, and law enforcement agencies 
        may be unable to address it.
    ``(2)(A) Except as provided in subparagraph (B), it shall be 
unlawful for any person to manufacture, sell, offer to sell, transfer, 
purchase, or receive a ghost gun in or affecting interstate or foreign 
commerce.
    ``(B) Subparagraph (A) shall not apply to--
            ``(i) the manufacture of a firearm by a licensed 
        manufacturer if the licensed manufacturer complies with section 
        923(i) before selling or transferring the firearm to another 
        person;
            ``(ii) the offer to sell, sale, or transfer of a firearm 
        to, or purchase or receipt of a firearm by, a licensed 
        manufacturer or importer before January 1, 2022; or
            ``(iii) transactions between licensed manufacturers and 
        importers on any date.
    ``(bb) It shall be unlawful for a person other than a licensed 
manufacturer or importer to engrave or cast a serial number on a 
firearm in or affecting interstate or foreign commerce.
    ``(cc) Beginning on January 1, 2022, it shall be unlawful for any 
person other than a licensed manufacturer or importer to possess a 
ghost gun in or affecting interstate or foreign commerce.
    ``(dd) Beginning on January 1, 2022, it shall be unlawful for any 
person other than a licensed manufacturer or importer to possess a 
ghost gun in or affecting interstate or foreign commerce with the 
intent to sell or transfer the ghost gun with or without further 
manufacturing or to manufacture a firearm with the ghost gun.
    ``(ee)(1) It shall be unlawful for any person to sell, offer to 
sell, or transfer, in or affecting interstate or foreign commerce, to 
any person other than a licensed manufacturer a machine that has the 
sole or primary function of manufacturing firearms.
    ``(2) Except as provided in paragraph (3), beginning on January 1, 
2022, it shall be unlawful for any person other than a licensed 
manufacturer to possess, purchase, or receive, in or affecting 
interstate or foreign commerce, a machine that has the sole or primary 
function of manufacturing firearms.
    ``(3) Paragraph (2) shall not apply to a person who is engaged in 
the business of selling manufacturing equipment to a licensed 
manufacturer who possesses a machine with the intent to sell or 
transfer the machine to a licensed manufacturer.''.
    (c) Requirements.--Section 923(i) of title 18, United States Code, 
is amended by adding at the end the following: ``The serial number 
shall be engraved or cast on the frame or receiver in a manner 
sufficient to identify the firearm and the manufacturer or importer 
that put the serial number on the firearm.''.
    (d) Penalties.--Section 924 of title 18, United States Code, is 
amended--
            (1) in subsection (a)(1)(B), by striking ``or (q)'' and 
        inserting ``(q), (aa), (bb), (cc), (dd), or (ee)''; and
            (2) in subsection (d)(1), by striking ``or (k)'' and 
        inserting ``(k), (aa), (bb), (cc), (dd), or (ee)''.

            (1) in paragraph (1)--

                striking ``any firearm'';

            ``(A) an undetectable firearm; or''; and
                    (C) in subparagraph (B), by striking ``any major 
                component of which, when subjected to inspection by the 
                types of x-ray machines commonly used at airports, does 
                not generate'' and inserting the following: ``a major 
                component of a firearm which, if subjected to 
                inspection by the types of detection devices commonly 
                used at airports for security screening, would not 
                generate'';

                    ``(ii) in the case of a rifle or shotgun, includes 
                the barrel of the firearm; and''; and
