Yes. If you repair firearms as a regular course of business for profit, federal law treats you as a dealer, and a gunsmith needs an FFL before taking in the first paying customer’s gun. The license that covers most repair work is the Type 01, which costs $200 for a three-year term and $90 to renew.1Office of the Law Revision Counsel. 18 USC 923 – Licensing Occasional repairs done outside a trade don’t require a license, and the difference between those two situations is where most of the law lives.
When Repair Work Crosses the Line Into Licensed Activity
Federal regulation defines a gunsmith, for licensing purposes, as a person who devotes time, attention, and labor to repairing firearms as a regular course of trade or business, with the principal objective of earning a livelihood and profit.2Bureau of Alcohol, Tobacco, Firearms and Explosives. 27 CFR Part 478 – Commerce in Firearms and Ammunition – Section 478.11 Meaning of Terms Part-time work counts. Evenings and weekends still count if the repairs are steady and paid.
The same regulation carves out the hobbyist. A person who makes “occasional repairs” or “occasionally fits special barrels, stocks, or trigger mechanisms” is not a gunsmith under federal law and does not need a license.2Bureau of Alcohol, Tobacco, Firearms and Explosives. 27 CFR Part 478 – Commerce in Firearms and Ammunition – Section 478.11 Meaning of Terms Helping a friend rebarrel a hunting rifle once a year is occasional. Advertising repair services and taking in several guns a month is not.
The Bipartisan Safer Communities Act of 2022 broadened the “engaged in the business” definition for firearms dealers generally, but the new language specifically excluded gunsmiths and pawnbrokers from that expanded definition.3Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Final Rule – Definition of Engaged in the Business as a Dealer in Firearms The traditional standard above still governs.
Work That Doesn’t Trigger the License
Not every service involving a firearm requires an FFL. Quick tasks completed while the customer is present, where you never really take possession, generally fall outside the definition. Mounting a scope, for example, is treated by ATF as neither machining nor manufacturing.4Bureau of Alcohol, Tobacco, Firearms and Explosives. ATF Ruling 2015-1 – Definitions (Firearm, Manufacturer, Dealer, Engaged in the Business) Swapping sights or installing a sling mount while the owner waits sits in the same category.
Basic cleaning, cosmetic touch-ups, and simple adjustments that don’t change how the firearm functions also stay below the threshold, provided they aren’t a steady paid service. Once minor jobs become a regular revenue stream, the “engaged in the business” standard applies regardless of how small each ticket is.
Type 01 or Type 07: Which License Fits the Work
Most gunsmiths need a Type 01 FFL, labeled “Dealer in Firearms Other Than Destructive Devices.” It covers repairing firearms and making or fitting special barrels, stocks, and trigger mechanisms, and it also allows occasional importing and retail sales.5Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Federal Firearms Licenses
A Type 07, “Manufacturer of Firearms Other Than Destructive Devices,” becomes necessary when the work crosses from repair into manufacturing. Assembling complete firearms from parts kits for sale, building custom rifles from raw materials, or permanently altering a firearm’s design all count as manufacturing under ATF definitions.4Bureau of Alcohol, Tobacco, Firearms and Explosives. ATF Ruling 2015-1 – Definitions (Firearm, Manufacturer, Dealer, Engaged in the Business) The Type 07 fee is $50 per year, cheaper on paper than the Type 01, but the obligations attached raise the real cost.1Office of the Law Revision Counsel. 18 USC 923 – Licensing
Any firearm manufactured under a Type 07 is subject to the federal firearms and ammunition excise tax when sold: 10% of the sale price for pistols and revolvers, 11% for all other firearms.6Office of the Law Revision Counsel. 26 USC 4181 – Imposition of Tax Type 07 licensees also file an Annual Firearms Manufacturing and Exportation Report and mark each firearm with the manufacturer’s name, city and state, and a unique serial number.7Bureau of Alcohol, Tobacco, Firearms and Explosives. 27 CFR 478.92 – Identification of Firearms and Armor Piercing Ammunition by Licensed Manufacturers and Licensed Importers None of that applies to Type 01 holders.
NFA Work Needs More Than an FFL
Suppressors, short-barreled rifles, short-barreled shotguns, and machine guns fall under the National Firearms Act, and an FFL alone doesn’t cover work on any of them. A gunsmith who deals in or manufactures NFA items must also pay an annual Special Occupational Tax. Class 2 (manufacturer) status costs $1,000 per year, reduced to $500 for businesses with gross receipts under $500,000. Class 3 (dealer) status is $500 per year.8Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Special Tax Registration and Return – National Firearms Act The tax period runs July 1 through June 30, with payment due by July 1 each year.9Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Instructions for Form 5630.7 – Special Tax Registration and Return Firearms
The SOT class must match the FFL. A Type 01 dealer who wants to repair customer-owned NFA items registers as a Class 3 SOT. A Type 07 manufacturer who wants to build or modify NFA items registers as a Class 2. Working on an NFA firearm without the correct SOT is a separate federal offense from operating without an FFL.
ITAR Registration Catches Many Type 07 Holders
Type 07 licensees face one more layer that surprises small shops: registration with the State Department’s Directorate of Defense Trade Controls under the International Traffic in Arms Regulations. Firearms are defense articles, and anyone engaged in the business of manufacturing them must register with DDTC even if they never export a single gun.
The threshold is lower than most expect. Manufacturing for ITAR purposes includes fabrication (casting, forging, machining, cutting) and permanent assembly (welding, brazing, riveting). Work that involves fabricating new parts, restoring dimensions on worn components through machining, or welding falls inside the definition. Standard repair using bolt-on replacement parts, testing, and inspection do not.10Directorate of Defense Trade Controls. Definition of Manufacturing for ITAR 122.1 Registration Requirements
The cost is steep. First-time registrants pay $3,000 per year under Tier 1 pricing, though a temporary $500 discount brings the first year to $2,500 for qualifying applicants. Subsequent years cost $4,000 or more depending on the number of export authorizations received.11U.S. Department of State, Directorate of Defense Trade Controls. Registration Payment For a one-person shop that occasionally machines a custom part, that annual fee can outweigh every other compliance cost combined.
State, Local, and Zoning Approvals
A federal license by itself doesn’t clear you to open. ATF notifies state and local authorities when someone applies for an FFL, and the application can be denied if the proposed business would violate local law.12Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Apply for a License Zoning is the common obstacle for home-based gunsmiths. Local ordinances may restrict proximity to schools, limit customer traffic in residential areas, or prohibit commercial signage on residential property.
Some states also require a separate state-level firearms dealer or gunsmith license with its own fees and renewal cycle. Others impose cash bonds, liability insurance, or sales tax collection obligations.13Bureau of Alcohol, Tobacco, Firearms and Explosives. Form 7/7CR Instructions – Application for Federal Firearms License Checking with the city or county clerk and the state licensing authority before filing the FFL application can prevent a denial that delays everything by months.
What Happens If You Operate Without a License
Running a gunsmithing business without the required FFL is a federal felony. Under 18 U.S.C. ยง 924, anyone who willfully engages in the business of dealing in firearms without a license faces up to five years in federal prison, a fine, or both.14Office of the Law Revision Counsel. 18 U.S. Code 924 – Penalties The statute requires proof that the violation was willful, meaning the person knew the conduct was unlawful or acted with reckless disregard for the licensing requirement.
Unlicensed gunsmiths also can’t receive firearms shipped across state lines, since interstate transfers have to go through an FFL holder. And customers who later discover a gunsmith was unlicensed have no assurance their gun was properly logged, which can create complications if the firearm is ever traced in an investigation.
Once Licensed: What Immediately Changes
Holding an FFL brings recordkeeping rules that start on day one. Licensed dealers must maintain an Acquisition and Disposition record, commonly called the bound book. Each firearm received has to be entered by the close of the next business day, and each disposition recorded within seven days. Acquisition entries capture the date received, the name and address of the person who dropped it off, the manufacturer, model, serial number, firearm type, and caliber or gauge. Disposition entries capture the date and the recipient’s name and address, or an FFL number if the recipient is another licensee, or a cross-reference to the Form 4473.15Bureau of Alcohol, Tobacco, Firearms and Explosives. 27 CFR 478.125 – Record of Receipt and Disposition Sloppy books are one of the most common reasons gunsmiths run into trouble during compliance inspections.
One practical rule that trips up new licensees: returning a repaired firearm to the person who brought it in does not require a NICS check or a Form 4473. The exemption is specific to the original owner. If the customer asks you to hand the finished gun to a spouse, friend, or anyone else, that becomes a standard transfer with a background check and Form 4473.16Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
