On January 13, 2023, the Attorney General signed ATF final rule 2021R-08F, “Factoring Criteria for Firearms with Attached ‘Stabilizing Braces” amending ATF’s regulations to clarify when a rifle is “designed, redesigned, made or remade, and intended to be fired from the shoulder.” This includes a weapon that is equipped with an accessory, component, or other rearward attachment (e.g., a “stabilizing brace”), that provides surface area that allows the weapon to be fired from the shoulder, provided other factors (as described in the rule) indicate the weapon is designed, made, and intended to be fired from the shoulder. The final rule is effective on the date of publication in the Federal Register.
