wonder if 7.2.3 would cause an issue if they considered you a gunsmith, particularly the parts I highlighted

7.2.3 What is the difference between manufacturing and gunsmithing? Performing the work of a gunsmith requires a dealer’s license under the GCA, not a manufacturer’s license.111 Nevertheless, a license as an importer or manufacturer also entitles the licensee to conduct business as a gunsmith. The term “dealer” under the GCA includes a gunsmith, that is, “any person engaged in the business of repairing firearms or fitting special barrels, stocks, or trigger mechanisms to firearms.” However, gunsmiths occasionally perform the work of a manufacturer and do so without the required manufacturer’s license. Indeed, there is no distinction between the activities of a gunsmith and a manufacturer in terms of the physical things done to a firearm. What distinguishes gunsmithing from manufacturing is the purpose for which the work is done. If a gunsmith performs work on a customer’s personal gun for the customer’s personal use, the function is lawfully performed pursuant to the gunsmith’s license as a dealer under the GCA. However, if the gunsmith performs work on guns as a step in the process of preparing them for subsequent sale, the work is “manufacturing” requiring a manufacturer’s license and, if the firearm is an NFA firearm, a special tax stamp under the NFA. Here are some examples:
