Federal prosecutors charged 48-year-old Jay Fisher on Tuesday with two counts of possessing firearms and ammunition while being an unlawful user of controlled substances.
Authorities raided Fisher's Reading home and business after he was arrested along with his wife and an employee on charges they kidnapped another man. Investigators say they recovered 168 firearms and more than 40,000 rounds of ammunition from the home.
Fisher is also charged with holding his wife and son hostage during a standoff with police.
Fisher remains in Berks County Prison in lieu of $175,000 bail. The attorney representing him on state charges was unavailable Wednesday.
