SIAP, ATF put out a proposal (or whatever they phrase it as) to redefine what a firearm is

quote:

---

Summary
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.
