On June 7, 2021, the Attorney General signed ATF proposed rule 2021R-08, “Factoring Criteria for Firearms with Attached ‘Stabilizing Braces,’” amending ATF’s regulations to clarify when a rifle is “intended to be fired from the shoulder.”

The proposed rule outlines the factors ATF would consider when evaluating firearms equipped with a purported “stabilizing brace” to determine whether these weapons would be considered a “rifle” or “short-barreled rifle” under the Gun Control Act of 1968, or a “rifle” or “firearm” subject to regulation under the National Firearms Act.
