Pathbound

Electronic Bound Book & Firearms Transaction System

Pathbound is the electronic acquisition and disposition record and firearms transaction system built by Pathfinder Defense LLC in Powell, Wyoming. It replaces paper bound books and paper Forms 4473, it covers every type of federal firearms license and special occupational tax (SOT) class, and it runs entirely on hardware owned and operated at the licensed premises.

Every record it holds is append-only. Nothing in this system can be edited or deleted. Corrections are added as new entries that supersede the old ones, and the originals stay exactly as they were written.

On the name. "Bound book" is ATF's own term for the acquisition and disposition record. Pathbound carries both readings: the bound record, and being committed to a course.

What it does

Pathbound keeps every federally required firearms record for a licensee in one place:

  • Acquisition and disposition records for every FFL type, with a separate, partitioned book for each license, so records from different licenses cannot be intermingled.
  • Forms 4473 completed by the customer on a tablet at the counter or at a gun show, reviewed, signed electronically, sealed in an unalterable format, and printed on demand.
  • National Firearms Act records for suppressors and other NFA firearms for every SOT class, alongside the Form 2 manufacturing-notice clock and the transfer forms.
  • Import records for importers: Form 6 permits, Form 6A releases, and the fifteen-day marking clock that starts when a shipment clears Customs.
  • Reports that used to be assembled by hand: the annual AFMER filing, multiple-sale reports, theft and loss reports, and the bound book itself, printed for any date range in any of the three views ATF requires.

How it keeps the records honest

The bound book is not a table of firearms that gets edited. It is a ledger: a sequence of permanent entries, each one hashed together with the one before it into a chain.

Nothing can be edited.

The database itself refuses updates and deletions on the record tables. Not the software: the database. An administrator with full server access cannot quietly change a line.

Corrections are additions.

Fixing an error writes a new entry that names the original, records what changed, why, and which two employees approved it. The original stays in the book. Both appear side by side when the book is printed.

The chain proves it.

Every entry carries a fingerprint computed from its own contents and the fingerprint of the entry before it. Change one character anywhere in the history and every fingerprint after it stops matching. The book can be verified from the first entry to the last in front of an inspector.

Nothing gets deleted.

No screen, button, or menu in this system deletes a Form 4473 or a bound-book entry. That capability was never built. The single narrow exception is ATF's own: destroying a redundant paper original after a verified scan, never the electronic record.


Where it lives

On a server in the building. Not in a cloud, not on a subscription, not in someone else's data center. The records are on the licensed premises, backed up nightly to a device on the licensed premises, and exported daily in plain readable form to a device on the licensed premises.

That is a deliberate choice. ATF Rul. 2016-1, condition 9 permits records to be stored on a server owned and operated by the licensee as an alternative to a contracted host facility. Taking that branch means the host-facility rules never apply, the records are physically here when an inspector walks in, and there is no third party between the licensee and its own records.


Built for inspections, not around them

Pathbound includes a read-only account for ATF Industry Operations with uninterrupted access to the stored Forms 4473 and the bound book, side by side, searchable by every field the regulations name. It has no write capability, no session timeout, no lockout, and no way for anyone here to throttle or interrupt it.

The design principle throughout: make the compliant path the only path. Deadlines are calculated and displayed, not remembered. A multiple handgun sale is caught the moment the second one is entered. An imported firearm cannot leave the book until its markings are recorded. A late entry is flagged permanently and cannot be un-flagged.

Capabilities in detail

Acquisition and disposition

Append-only ledger, one per license, hash-chained and independently verifiable. Consolidated acquisition and disposition records. Entry deadlines calculated per license type, frozen at the moment of entry and displayed on a countdown. Duplicate acquisitions blocked at the database. Manufacturing conversions recorded as the paired disposition-to-self and acquisition-from-self the rulings require, with the firearm remaining logged in throughout the work. Transfers between a licensee's own licenses recorded as full dispositions and acquisitions on both books, with a nightly reconciliation that catches any orphaned leg.

Firearms Transaction Records

Customer-facing kiosk mode on a tablet. The customer's sections are never pre-populated from any prior transaction; the kiosk account has no ability to read a previous form at all. Answers stay amendable until the certification is executed, then lock permanently. Signatures are bound to one field on one form and cannot be reused. Completed forms are flattened, sealed, hashed, and written to write-once storage. Denied, cancelled, and expired transactions are retained the same as completed ones.

Background checks

NICS transaction capture with the Brady transfer date calculated from the response, including the extended window for transferees under twenty-one. Wyoming Concealed Firearm Permit exception evaluated against all five statutory tests, including the one most often missed: the permit must have been issued within five years, not merely be unexpired. Approved National Firearms Act transfers recognized as a background check exception.

National Firearms Act

Records under 27 CFR 479.131 maintained alongside the Gun Control Act bound book for every NFA firearm. Form 2 manufacturing notice raised as a blocking obligation due the close of the next business day after manufacture. Serialization and marking recorded and verified before a Form 2 will print. Firearms on a pending Form 4 remain in inventory and on the books until the transfer actually occurs. Forms 1, 2, 3, 4, 5, 5320.20 and 5320.23 generated pre-filled and print-ready; approved stamps attached to the record.

Importation

Form 6 permits tracked from application through approval and expiration. Customs release starts the fifteen-day marking clock and the fifteen-day acquisition-entry clock in parallel. An imported firearm cannot be disposed of or transferred to another license until the importer's name, city and state, country of manufacture, and a conforming serial number are all recorded as applied.

Reporting

The bound book printed for any date range, any license, in original-entries-only, corrected-entries-only, or both-together form, with a chain verification stamp on every page. AFMER (Form 5300.11) generated for manufacturers with a backing worksheet naming every serial number behind every box, including the ones excluded and why. Multiple handgun sales detected across a five-business-day window and blocked from closing until Form 3310.4 is generated. Theft and loss reports. The complete out-of-business record package.

Gun shows and events

Offline capture at gun shows, with sequence numbers reserved before departure and any unused numbers voided on return with a written, hash-chained explanation, so no gap in the book is ever unexplained. Every away-from-premises entry records the location of the transaction.

ATF notification letters

Keeping records electronically starts with written notice to ATF. ATF Rul. 2022-01 requires sixty days' written notice to your ATF Industry Operations Area Office before Forms 4473 are kept electronically, for each license. Pathbound raises that notice as an obligation on the first day it runs, so it is not missed. If you use Pathbound, we can give you template notification letters to help you prepare and send them.

What it deliberately does not do

  • It does not delete records. No retention purge, no archive-and-remove, no administrative override. The capability does not exist in the application.
  • It does not submit to ATF electronically. There is no public interface to ATF eForms or to NICS. Pathbound fills forms out, prints them, tracks their status, and enforces every deadline. A person files them.
  • It does not talk to the internet. The records server has no inbound public interface.

Regulatory authority

Electronic firearms recordkeeping is not a right that software vendors grant. It is an alternate method or procedure, a variance, that ATF authorizes under 27 CFR 478.22 and 27 CFR 479.26, on the condition that the licensee satisfies every requirement the ruling sets out. Four rulings authorize it:

RulingSubjectAuthority for
ATF Rul. 2016-1Requirements to Keep Firearms Acquisition and Disposition Records ElectronicallyThe bound book
ATF Rul. 2016-2Requirements for the Completion of ATF Form 4473 ElectronicallyThe kiosk
ATF Rul. 2016-3Consolidation of Required Records for ManufacturersManufacturer conversions
ATF Rul. 2022-01Electronic Storage of Forms 4473The sealed form archive

Each of the four rulings closes with the same language, in substance:

If the licensee fails to abide by the conditions of this ruling, uses any procedure that hinders the effective administration of the federal firearms laws or regulations, or any legal or administrative difficulties arise, the licensee is no longer authorized to use the electronic method under this ruling and must revert to paper.

That sentence is the reason Pathbound is built the way it is. Immutability is enforced in the database rather than the application, because an application-level promise is not a control. Corrections are additions, because condition 2(a) requires the original to survive. The ATF read-only account has no throttle, no lockout, and no maintenance page, because condition 5 requires access to be uninterrupted.

Every control in Pathbound is registered against the specific condition that requires it, the code that implements it, and the test that proves it still holds. That register is the document handed to an Industry Operations Investigator at the start of an inspection.

Citations were checked against the primary ATF or CFR documents on September 2, 2026. They are provided for reference and are not legal advice. ATF rulings and procedures are agency guidance and variance authorities; the CFR sections and final rules cited are binding. Verify currency before relying on any of them.

For other licensees

Pathbound was written at Pathfinder Defense and can be installed by any licensee, whatever their FFL type and SOT class. It is not a commercial product and is not sold. It is given to other federal firearms licensees free of charge, as is. Nothing about it is hosted: it runs on your hardware, at your licensed premises.

Before you ask for it

  • ATF Rul. 2022-01, condition 1: sixty days' written notice to your ATF Industry Operations Area Office before Forms 4473 are retained electronically, per license. Pathbound raises this as an obligation on the first day it runs and cannot discharge it for you, but we can give you template notification letters to help.
  • ATF Rul. 2016-1, condition 3: once any A&D record is kept electronically, all of them must be. There is no partial changeover.

The terms

Pathbound is provided free and as is, with no warranty of any kind, express or implied, and no representation that it is fit for any particular licensee or any particular ATF field division. There is no support obligation, no service level and no undertaking to maintain it.

The licensee remains responsible for the accuracy, completeness and retention of their own records, for the notices and conditions above, and for producing the records to ATF. Nothing in this program or its documentation is legal advice.

There is no telemetry, no account, no license key and no call home. The author cannot see another licensee's records and has no mechanism to.
