BRENTWOOD, CA — U.S. Marshals arrested a man who allegedly manufactured firearms with a 3-D printer
inside his bedroom at his parents house in Brentwood.
Noah K. Bauer, 22, remains in custody at the West County Detention Facility, pending a March 17 detention hearing.
Bauer became the subject of a FBI investigation, following an incident at Raley’s grocery store on
Sand Hill Road. Brentwood officers found Bauer at the store in possession of an unregistered firearm
on September 6, 2024. The police retrieved from his waistband a 3D printed Glock-style pistol.
Brentwood PD arrested Bauer that day for possession of a concealed firearm. A search of his
residence turned up evidence of illicit firearms manufacturing.
Officers found a 3D printing machine, three 3D printed pistol frames and a 3D printed machine gun conversion device. Incriminating website
history was also found.
Bauer’s arrest in September 2024 prompted a subsequent FBI investigation of him. It was conducted
the domestic terrorism squad of the FBI field office in San Francisco. Consequently, Bauer was arrested by the U.S. Marshals Service on March 11. He is presently ineligible for release on bond.
An FBI complaint filed against Bauer alleges that he possessed a 3D printed machine gun conversion
device.
Such a device can be used to convert semiautomatic firearms to fully automatic machine guns.
Bauer reportedly told Brentwood police the conversion device was intended to make firearms “shoot
faster.”
Bauer faces a federal charge for possession of a conversion device for the transfer/possession of a
machine gun. If convicted, Bauer faces a maximum sentence of 10 years in prison, and a fine of
$250,000.’
