U.S. Government Appeals Pistol Brace Decision to 5th Circuit

After nearly three months of silence, the U.S. Government has now appealed the June 13, 2024, pistol brace decision to the U.S Court of Appeals for the Fifth Circuit.

The appeal was announced on August 12, 2024.

The case is Mock v. Garland, and it was brought by the Firearms Policy Coalition.

The ATF pistol brace rule targets stabilizer braces attached to AR pistols, claiming the braces turn AR pistols into short barrel rifles (SBRs). And since SBRs are regulated under the National Firearms Act (1934), the ATF issued its rule on AR-pistol braces to stop what it saw as a way around SBR regulations.

Breitbart News reported that U.S. District Judge Matthew J. Kacsmaryk issued a preliminary injunction against the AR pistol brace rule on November 8, 2023.

Kacsmaryk observed that the “court is not insensitive to the ATF’s concerns over gun industry gamesmanship and attempts to circumvent the rules on SBRs.” But he followed that acknowledgement by quoting Bruen (2022), noting that the government may not justify the passage and/or existence of a regulation by “simply [positing] that the regulation promotes an important interest.”

In a decision dated June 13, 2024, U.S. District Judge Reed O’Connor vacated the ATF’s AR pistol brace rule, saying it violated the Administrative Procedure Act (APA).

The U.S. Government has now appealed the pistol brace decision to the Fifth Circuit.

Breitbart News pointed out the Fifth Circuit decided against another ATF rule–a ban on bump stocks–on January 6, 2023. The court did so in light of the ATF’s arbitrary recategorization of bump stocks as “machine guns.”
