TUCSON, Ariz. – Damien Jax Schaffer, 45, of Tucson, was arrested on June 24, 2025, by Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) special agents, and charged by criminal complaint for Engaging in the Business of Dealing in Firearms without a License and Possession of an Unregistered Firearm. Schaffer appeared in court today for his initial appearance.
According to the complaint, from May 8, 2025, through June 24, 2025, ATF monitored Schaffer and learned that he had manufactured and sold 15 illegal machinegun conversion devices. These devices are used to allow semi-automatic firearms, like Glocks, to expel more than one projectile with a single press of the trigger, effectively converting a semi-automatic firearm into a machinegun.
Machinegun conversion devices are required to be registered with ATF in the National Firearms Registration and Transfer Record. After learning of Schaffer’s activities, ATF agents queried that record and determined that his devices were not registered to anyone. Agents also learned that Schaffer does not possess a federal license to sell firearms.
This case was part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).
A criminal complaint is simply a method by which a person is charged with criminal activity and raises no inference of guilt. An individual is presumed innocent until evidence is presented to a jury that establishes guilt beyond a reasonable doubt.
ATF is conducting the investigation in this case. The United States Attorney’s Office, District of Arizona, Tucson is handling the prosecution.
