The book of: Firearms Dealers (Federal Firearms License)
Introduction
Every federal rule for holding and running a firearms license, in plain English — organized so you can read it once to get licensed, and reach for it every week after that.
A trade that comes with a rulebook
Most people who end up holding a Federal Firearms License did not set out to become compliance professionals. They set out to run a gun shop, or to build rifles, or to bring in something interesting from abroad. The license arrives, and with it a body of federal regulation that assumes you already know how to read it.
That regulation is real, it is detailed, and it is unforgiving in a specific way: almost nothing in it goes wrong dramatically. Licenses are lost over records that were not kept, notices that were not answered inside their clock, and forms filled in the way someone was told to fill them in years ago. The rules that end businesses are rarely the ones anybody found interesting.
This book is the rulebook, rewritten so you can actually use it.
What this book is
It is a plain-English reference built directly from the official text — 27 CFR Part 478, which governs commerce in firearms and ammunition, and 27 CFR Part 479, which governs the National Firearms Act side of the business. Nothing in the chapters is a summary of a summary. Every rule traces to the pinned regulation it comes from, and where the regulation does not settle a question, this book says so rather than filling the gap with something that sounds right.
It is not legal advice, and it is not a substitute for the regulation itself. It is the version you can read.
Who it is for
Two readers, and the book is written for both at once. The first is applying — working out which license category fits, what the application asks, and what happens if the answer is no. The second already holds a license and is running the compliance side of a shop: the bound record, the transaction forms, the reporting clocks, and the inspection that eventually arrives.
If you are the first reader, the early chapters are your path in and the later ones are what you will grow into. If you are the second, the book is organized so you can go straight to the chapter that matches the thing in front of you.
How this book is built
From the source, not from summaries
Every chapter is written against a pinned snapshot of the official regulation. Claims trace to the text; nothing is asserted because it is common knowledge in the trade.
Reviewed for accuracy and for readability
Each section is checked twice — once against the source by a compliance reviewer, once for comprehension by a reader with no background at all. Both have to pass.
Kept current
When the underlying regulation changes, the affected sections are regenerated and your copy updates. A printed rulebook goes stale on the shelf; this one does not.
How the book is organized
The order follows the life of a license rather than the order of the regulation. Chapters 1 to 4 are about getting and keeping one: what the law covers, who must be licensed, how to apply, how to keep the license current through the changes a business goes through, and what happens when ATF says no.
Chapters 5 to 9 are about using one. The counter transaction and the checks around it; the transactions that happen away from the counter; marking and identifying firearms; the records; and the three events you must report without being asked.
Chapters 10 to 12 are the specialist ground. Importation, which is a separate permission from the license to deal. The National Firearms Act layer, with its own tax, its own applications, and its own registry. And finally what the law does when things go wrong — false statements, seizure and forfeiture, the relief that exists, and the last obligation a license carries on the day the business closes.
How to read a section
Before you start
Two habits will serve you better than memorizing anything here. The first is to notice the clocks. A surprising amount of this regulation is not about what you may do but about how long you have to do it, and almost every one of those periods runs from an event rather than from the day you noticed — discovery, receipt, service, discontinuance.
The second is to remember that federal law is a floor. Your state and your locality can require more of you, and this book covers only the federal layer. Where a question turns on state law, the book says so rather than answering it for you.
