69 guns were seized during a raid in Central Oregon.
Earlier this month Central Oregon Drug Enforcement started investigating 66-year-old Eric Testerman, of Bend, for making and selling ghost guns.
They don't have serial numbers and are often used in crimes.
During the search of a home in Bend they found short-barrel rifles and automatic firearms. They also found manufacturing equipment used to make unserialized guns.
Testerman wasn't there and hasn't been arrested. The case will be considered by a grand jury to determine charges.
