UPDATE: The ATF’s 2023 “Factoring Criteria for Firearms with Attached Stabilizing Braces” rule, which reclassified many braced pistols as Short-Barreled Rifles (SBRs), has been effectively vacated by federal courts, including rulings by the Fifth Circuit. These court decisions found the rule arbitrary, capricious, and a violation of the Administrative Procedure Act.
The Bureau of Alcohol, Firearms, Tobacco, and Explosives (ATF) filed new regulations on January 13th, 2023, classifying certain rifles with a stabilizing brace as short-barreled rifles. Rule submission 2021R-08F, titled “Factoring Criteria for Firearms with Attached ‘Stabilizing Braces’” was signed by the US Attorney General, which clears the way for the rule to become active once it is published in the Federal Register. Owners of an estimated 3 to 7 million reclassified firearms will then be required to:
- register for a federal license within 120 days,
- remove the stabilizing brace from their firearm,
- replace the short barrel with a barrel 16 inches or longer, or
- surrender the firearm to the ATF.
The rule includes language waiving the usual fees and taxes required to register similar firearms if the firearm is registered within the 120-day period. Registering is done using ATF Form 1, Application to Make and Register a Firearm. Form 1 has been an eForm since November, so you will need to become registered to submit an eForm on the ATF website to begin the process. Registration is on the ATF website, or use the link below under references as a starting point before you register. But note that the link to register under this rule is different from the one on the regular Form 1 page.
The ATF guidance on the process states that you can either send fingerprint cards or submit fingerprints electronically. We can provide you with either FD-258 fingerprint cards or an Electronic Fingerprint Transmission (EFT) file, depending on which process you choose when submitting Form 1. To schedule your fingerprinting appointment, use the appointment link on our website.
