ATF Compliance at Gun Shows: Manifests, 4473s & Off-Premises Sales

Selling at a gun show doesn’t relax a single recordkeeping requirement — it just removes the infrastructure that makes compliance easy. Here’s what applies when your inventory leaves the licensed premises, and how disciplined dealers keep a clean trail.

The baseline: where you can sell

Federal law permits a licensee to conduct business at a gun show or event located in the same state as the licensed premises. At an out-of-state show you can display and take orders, but the actual transfer has to happen where the law allows it — typically back at your premises or through a licensee in the buyer’s state.

State and local layers stack on top: waiting periods, permit verification, and restrictions differ by state and sometimes by county or venue. Verify them per show — promoters won’t do it for you.

Every transfer is still a full transfer

At a show, exactly as at the counter, every sale to a non-licensee requires a completed Form 4473 and a NICS check. Common show-floor failure modes:

Incomplete 4473 fields — the most frequent inspection finding industry-wide, and rushed show transactions make it worse. Digital 4473s with field validation catch omissions before the buyer walks away; ATF Rulings 2016-2 and 2022-1 authorize electronic completion and storage.
Connectivity assumptions — venue WiFi failing mid-transaction strands cloud-only systems. An offline-first 4473 workflow keeps forms moving; phone-in NICS remains the fallback.
Multiple-sale reporting — two or more handguns to the same buyer within five consecutive business days triggers ATF Form 3310.4, and busy shows are exactly where this sneaks up on you.

Off-premises inventory: the chain of custody problem

Your A&D bound book says a firearm is in your inventory. For a weekend, “your inventory” is a bin in a convention center. If anything goes missing, you need to demonstrate what left, what sold, and what returned — with times and records, not memory.

The discipline that survives an inspection:

A show manifest — every serialized item leaving the premises, documented before departure.
Container-level tracking — which firearm traveled in which container. QR-coded containers with scan logs and GPS timestamps turn “I think it was in the gray bin” into a documented chain of custody.
Live disposition logging — each sale posts to the bound book as it happens (or queues offline and posts on sync), inside the required recording window.
Return reconciliation — manifest out minus dispositions must equal manifest back in. Any imbalance is investigated immediately; a theft or loss discovered at reconciliation requires prompt reporting (ATF Form 3310.11 and local law enforcement).

The bound book doesn’t pause for the weekend

Acquisitions must be recorded within one business day of receipt and dispositions within the required window — show sales included. Paper workflows tend to batch this into a Monday data-entry session, which is where transposed serials and missed entries are born. An electronic bound book that receives dispositions automatically from show sales removes the batch. (How that works: our electronic bound book, built on ATF Ruling 2016-1.)

The Sunday-night audit that saves the license

Reconcile the manifest to zero unexplained items.
Review every 4473 for completeness — every field, every signature.
Confirm all dispositions posted to the A&D book.
File any multiple-sale reports triggered during the show.
Document any discrepancy with what you know, when you knew it, and what you did.

Dealers who do this after every show walk into ATF inspections with nothing to reconstruct. Dealers who don’t are betting their license on memory.

Automating the whole loop

Gun Show BRO exists because this workflow is miserable on paper: it builds the manifest as you scan containers, completes 4473s offline, posts dispositions on sync, reconciles automatically, and flags discrepancies while you’re still at the show. $149/month standalone. Start with the gun show checklist, or request a demo.

General information, not legal advice. Requirements change — verify current ATF, state, and local rules for every show, and consult a firearms attorney for specific situations.
