Federal agents raided a California gun parts store over the weekend after the owner refused to hand over his list of customers.
Dimitrios Karras owns Ares Armor in Oceanside, where people can buy various gun pieces to build their own rifle.
According to a Fox News affiliate in San Diego, it is legal to build a rifle from scratch without serial numbers if the base is manufactured to specifications outlined by the Bureau of Alcohol, Tobacco, Firearms and Explosives.
A manufacturer for Ares Armor made thousands of 80 percent receivers in plastic with indicators that show customers exactly where to drill. ATF said the receivers are illegal and demanded Mr. Karras hand over the inventory and the names of the 5,000 customers who purchased them.
He agreed to handing over the products, but not the names of his customers.
“They said either give us these 5,000 names or we are coming in and taking pretty much anything — which is a huge privacy concern and something we are not willing to do,” Mr. Karras told the station.
Mr. Karras filed a temporary restraining order against the ATF, but under pressure by the Department of Justice, federal Judge Janis L. Sammartino reversed the order and heavily armed ATF agents went ahead with the raid, confiscating the gun parts and computers containing customer information.
According to Town Hall, undercover and plain-clothed ATF agents were questioning customers outside of the store.
Mr. Karras met with attorneys on Sunday and plans to take further legal action to get the computers back, a local NBC affiliate reported.
