Yes. Amended regulations at 478.92(a)(1)(v) allow manufacturers and importers to mark the component of a firearm (other than a privately made firearm (PMF)) defined as a frame or receiver prior to August 24, 2022, in the same manner as before the effective date of the final rule. The final rule makes clear that almost all firearms ATF previously classified as falling within the definition of ‘‘frame or receiver’’ prior to issuance of the final rule are grandfathered and may continue to be marked in the same manner as before the effective date of the final rule. The only exceptions are certain ATF classifications of partially complete, disassembled, or nonfunctional frames or receivers.
