ATF Q&A: Licensing

What are the compliance options for an FFL holder in possession of firearms equipped with a "stabilizing brace," which is an SBR, after the effective date of the final rule?

  • For SBRs equipped with a “stabilizing brace” that are in their possession, complete and submit through the eForms system a Notice of Firearms Manufactured or Imported, ATF Form 2 within 120-days from the date of publication in the Federal Register.
  • Permanently remove or alter the “stabilizing brace” so that it cannot be reattached and thereby removing it from regulation as a “firearm” under the NFA.
  • Remove the short barrel and attach a 16-inch or longer rifled barrel to the firearm thus removing it from the provisions of the NFA.
  • Turn the firearm into your local ATF office.
  • Destroy the firearm. For more information go to How to Properly Destroy Firearms | Bureau of Alcohol, Tobacco, Firearms and Explosives (


Guidance is provided by The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
