A 25-year-old Tulsa man and former member of the US Army National Guard has been charged with attempting to provide material support to a terrorist organization after allegedly trying to ship 3-D printed weapons parts to an undercover FBI agent he believed was working on behalf of al-Qaida.

Federal prosecutors unsealed a criminal complaint Wednesday against Andrew Scott Hastings, accusing him of attempting to provide material support or resources to a designated foreign terrorist organization and illegally possessing and transferring a machine gun.

According to court records, the FBI began monitoring Hastings in June 2024 after he discussed on a social media app committing acts of violence against US civilians to advance “global jihad.” Hastings, who had served in the National Guard as an aircraft powertrain repairer and held a national security clearance, allegedly encouraged others online to pursue both cyberspace skills and physical combat training.

Investigators say Hastings offered to share over 500 pages of personal notes and Army training manuals covering weapons tactics and manufacturing. He also reportedly boasted about creating a firearm, expressed interest in developing a nuclear weapon, and praised Hamas’s use of tunnels for militant operations.

Hastings allegedly began communicating with an undercover FBI agent who presented himself as having ties to al-Qaida. Their conversations turned to 3-D printed firearms, illegal machinegun conversion devices known as “switches,” and drones. Hastings eventually sent the agent a website link where he offered 3-D printed switches for sale.

Surveillance footage later captured Hastings twice visiting a postal facility to ship packages that included more than 100 3-D printed switches, two 3-D printed lower receivers for a handgun, a handgun slide, and other firearm components. Prosecutors say he believed the parts would be supplied to al-Qaida for use in terrorist attacks.

During the FBI’s investigation, Hastings agreed to voluntarily discharge from the National Guard on June 6, 2025.

The case is being investigated by the FBI’s Joint Terrorism Task Force in Tulsa, the Army Counterintelligence Command, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and the Tulsa Police Department. Assistant U.S. Attorneys Nathan E. Michel, Matthew P. Cyran, and Christopher J. Nassar are prosecuting the case with support from Trial Attorney Elisa Poteat of the Justice Department’s Counterterrorism Section.
