Effective June 14, 2024, ATF ceased enforcement of the Final Rule titled "Bump-Stock-Type Devices" (2018R-22F). This update follows the U.S. Supreme Court’s decision in Garland v. Cargill, 602 U.S. 406 (2024), which held that a semiautomatic rifle equipped with a [non-mechanical] bump stock does not meet the statutory definition of a "machinegun" under the National Firearms Act (NFA), 26 U.S.C. § 5845(b).
The Department of Justice is amending the Bureau of Alcohol, Tobacco, Firearms, and Explosives regulations to clarify that “bump fire” stocks, slide-fire devices, and devices with certain similar characteristics (“bump-stock-type devices”) are “machineguns” as defined by the National Firearms Act of 1934 (NFA) and Gun Control Act of 1968 (GCA), because such devices allow a shooter of a semiautomatic firearm to initiate a continuous firing cycle with a single pull of the trigger.
