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 Attorney General is ratifying a final rule, published in the Federal Register on December 26, 2018, that amended the definition of ‘‘machinegun’’ (or ‘‘machine gun’’) in Department of Justice regulations. The ratification is issued as a prudential matter in light of pending litigation.
