Curtis sent BATFE’s formal reply, several excerpts from which are reprinted here (bold and underline are BATFE’s emphasis): manufacturers that sell roller-delayed blowback firearms without full-auto carrier blocks but with metal shelves are not considered by BATFE to be selling machine gun receivers. manufacturer license Zenith Firearms were to remove the full-auto carrier blocks from its upper receivers, after importation, and then sell those upper receivers either as stand-alone parts or as components of partially or fully assembled firearms, provided their metal shelves were still in-tact, Zenith Firearms would not have sold any machine gun receivers, just as other U.S. In an Augletter to FTISB Chief Michael Curtis, we contended as follows: In 2018, Zenith requested from BATFE a corroborating opinion, on the basis of an argument that we set forth, of the lawfulness of our company engaging in the post-import removal of full-auto bolt carrier blocks.
