Submit a Comment to ATF to Protect Pistol Stabilizing Braces

On June 7, 2021, the ATF proposed a rule on pistol stabilizing braces that’s going to impact millions of Americans. They’re calling it: Factoring Criteria for Firearms with Attached “Stabilizing Braces.”


Here are a couple key highlights in this notice of proposed rulemaking (NPRM):


  • ATF is trying to update the definition of a rifle to include any weapon with a rifled barrel that has a stabilizing brace because they believe firearm owners are using these pistol stabilizers with the intent of converting pistols into short-barreled rifles.
  • ATF would apply a “point system” (up to 4 points) to determine whether a pistol stabilizer would convert and classify it as a short-barreled rifle.  


If this rule goes into effect, it will be the largest firearms ban in the entire history of the United States that will impact millions of Americans with privately-owned firearms (including thousands of jobs in the firearm industry). These firearms will suddenly become unlawfully possessed  unless owners do the following:


  • Add a longer barrel to the firearm so it won’t be considered a short-barreled rifle
  • Surrender the firearm to ATF 
  • Completely remove and destroy the pistol stabilizer (if the firearm was assembled from scratch). 
  • Completely destroy the firearm (if it was an OEM-made firearm because a pistol cannot be made from something that was first manufactured as a rifle).  
  • Pay ANOTHER $200 tax and register the firearm with ATF.  



That means millions of Americans will become felons by owning these items if this rule gets put in place. 


For the sake of gun owners across the country (including yourself) who own a pistol stabilizing brace for your firearm, we need your help to stop this.
