A Medford man is facing a slew of felony charges following a sweeping law enforcement operation that uncovered more than 100 illegal firearms, dozens of suppressors, 3D printers, and a clandestine gun manufacturing setup—marking the largest ghost gun seizure in Suffolk County history.

Daniel Probeck, 35, was indicted on multiple charges including the criminal sale and possession of firearms after a months-long investigation led by the Suffolk County District Attorney’s Office in partnership with the Suffolk County Police Department. Officials say Probeck allegedly built and sold illegal, untraceable firearms—commonly referred to as “ghost guns”—out of his Long Island residence.

“This defendant was not simply a firearms collector,” said Suffolk County District Attorney Raymond A. Tierney. “He is alleged to have manufactured and sold illegal firearms for profit. I applaud the work of my office and the Suffolk County Police Department on getting this source of illegal weapons off the street.”

Authorities began investigating Probeck in March 2025, targeting his suspected role in the illegal sale of unserialized guns—firearms without serial numbers, making them difficult for law enforcement to trace. During the probe, Probeck allegedly sold multiple firearms, including three assault-style rifles, to an undercover officer in exchange for cash.

Following his arrest on June 12, law enforcement executed a search warrant at Probeck’s home and discovered a trove of illegal weapons and tools used for manufacturing them. Among the items seized were:

  • Over 112 illegal firearms, including assault weapons with features banned under New York State law
  • 67 sound suppressors
  • 12 three-dimensional (3D) printers
  • Large quantities of ammunition
  • Unfinished gun components and specialized tools used to build firearms

Officials described several of the recovered firearms as being equipped with threaded barrels, pistol grips, telescoping stocks, collapsible stocks, and flash suppressors—all considered illegal modifications under state law.

Probeck was arraigned on July 9 before Acting Supreme Court Justice Richard I. Horowitz on the following charges:

  • Criminal Sale of a Firearm in the First Degree (Class B violent felony)
  • Criminal Possession of a Weapon in the First Degree (Class B violent felony)
  • Criminal Sale of a Firearm in the Second Degree (Class C violent felony)
  • Criminal Possession of a Weapon in the Second Degree (Class C violent felony)
  • Four counts of Criminal Possession of a Weapon in the Third Degree (Class D violent felonies)

Probeck was remanded on $500,000 cash bail, $2 million bond, or $3 million partially secured bond. He is due back in court on August 5. If convicted on the top charge, he faces up to 25 years in prison, followed by five years of post-release supervision.
