Federal Judge Strikes Down ATF 'Ghost Gun' Rule for 3D Printed Parts

Court Overturns ATF Regulation

Judge Reed O’Connor of the U.S. District Court for the Northern District of Texas invalidated an ATF ruling that mandated firearm parts kits, readily convertible into functional weapons, frames, or receivers, be regulated identically to complete firearms. This decision has implications for the 3D printer market, particularly in states like California, Colorado, New York, and Washington State, which have implemented bans and limitations on 3D printers to address "ghost guns."

Constitutional Grounds for the Ruling

The judge determined that the ATF rule "contradicts the actual historical tradition of personal gunsmithing" and that its ambiguity violates the Due Process Clause of the Fifth Amendment. O'Connor's legal opinion stated that regulations on self-built arms are not longstanding, noting the absence of restrictions on personal arms manufacturing in early American history. This led the court to conclude that the rule's broad regulations, which restrict access to component parts and inhibit home gunsmithing, do not align with the Second Amendment.

Background of the ATF Rule

The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) implemented the rule in 2022. It required retailers to conduct background checks for purchasers of parts kits used to build firearms. The rule also provided clear definitions for firearm frames and receivers, specified which gun parts require serial numbers, and mandated that gun sellers and gunsmiths add serial numbers to 3D-printed and other non-serialized firearms. Additionally, it extended record-keeping requirements from two decades to the entire duration of a license. These regulations were intended to control "ghost guns," which are increasingly used in crimes and are difficult for authorities to trace.

Previous Supreme Court Action

The U.S. Supreme Court had previously upheld this ATF regulation in March of the prior year, following challenges from gun rights groups and manufacturers. These groups argued that the ruling exceeded the authority granted to the ATF by Congress. The Supreme Court, in a 7-2 vote, determined that the agency acted within its rights. However, Justice Neil Gorsuch's opinion focused on the constitutionality of the order, which is now at the center of Judge O'Connor's ruling.
