NEW ORLEANS, LA (June 21, 2023) – Today, Firearms Policy Coalition (FPC) announced the filing of a reply brief with the Fifth Circuit Court of Appeals in Mock v. Garland, FPC and FPC Action Foundation’s challenge to ATF’s pistol brace rule. The brief was filed less than one month after the Court clarified that its injunction against the rule covers FPC’s members. The brief, which was the final filling in the case before oral argument, can be viewed at

“Nothing in Appellees’ rehashed arguments alters the conclusion already reached by the motions panel,” argues the brief. “Appellants remain likely to win on the merits because a braced pistol is a constitutionally protected bearable arm, and the Agencies have not met their burden of showing that the right to keep and bear arms historically allowed NFA-like regulation of braced pistols or SBRs, however defined.”

Plaintiffs are requesting that the Fifth Circuit issue a preliminary injunction to preserve the status quo while they argue their full case–functionally extending the injunction beyond just the length of the appeal. The case is set for argument before the Fifth Circuit on June 29th.

FPC and FPCAF have specifically requested an injunction that will extend to all individuals, not just Plaintiffs and their members and customers: “The public has no interest in the unlawful enforcement of [ATF’s] rule and the irreparable harms that accompany it. This Court should thus reverse the district court and enter a nationwide preliminary injunction to prevent these harms.”

“All we’re asking is for the Fifth Circuit to ensure that peaceable people across the United States are protected from ATF’s enforcement of its unlawful and unconstitutional pistol brace rule for the length of the case,” said Cody J. Wisniewski, FPCAF’s Senior Attorney for Constitutional Litigation and FPC’s counsel in this case. “The firearms at issue here have been properly treated as pistols for a decade; we simply want to preserve that status quo while we make our full case to the Court.”
