ATF Proposed Rule 2021R-05: Definition Of “Frame Or Receiver” And Identification Of Firearms

This proposed rule would:

  • Provide new definitions of “firearm frame or receiver” and “frame or receiver”
  • Amend the definition of:
    • “firearm” to clarify when a firearm parts kit is considered a “firearm,” and
    • “gunsmith” to clarify the meaning of that term and to explain that gunsmiths may be licensed solely to mark firearms for unlicensed persons.
  • Provide definitions for:
    • “complete weapon,”
    • “complete muffler or silencer device,”
    • “privately made firearm (PMF),” and
    • “readily” for purposes of clarity given advancements in firearms technology.
  • Provide a definition of “importer’s or manufacturer’s serial number”
  • Provide a deadline for marking firearms manufactured.
  • Clarify marking requirements for firearm mufflers and silencers.
  • Amend the format for records of manufacture/acquisition and disposition by manufacturers and importers.
  • Amend the time period records must be retained at the licensed premises.
