ATF FAQ Gunsmithing
<span style="color: #3333FF">Q: Is a license needed to engage in the business of engraving, customizing, refinishing or repairing firearms?
Yes. A person conducting such activities as a business is considered to be a gunsmith within the definition of a dealer.
[27 CFR 478.11]
Q: Does a gunsmith need to enter in a permanent “bound book” record every firearm received for adjustment or repair?
If a firearm is brought in for repairs and the owner waits while it is being repaired or if the gunsmith is able to return the firearm to the owner during the same business day, it is not necessary to list the firearm in the “bound book” as an “acquisition.” If the gunsmith has possession of the firearm from one business day to another or longer, the firearm must be recorded as an “acquisition” and a “disposition” in the permanent "bound book" record.</span></div></div>
The actual definition of "engaged in the business" in the CFR is a little more instructive than the BATFE's FAQ:
"Gunsmith. A person who devotes time, attention, and labor to engaging in such activity as a regular course of trade or business with the principal objective of livelihood and profit, but such a term shall not include a person who makes occasional repairs of firearms or who occasionally fits special barrels, stocks, or trigger mechanisms to firearms;"
I'm sure the OP can figure out if he needs a license or not.
