What Is a Ghost Gun or Privately Made Firearm
Terminology, common misconceptions, and why precise definitions matter.
EC Enterprises provides gunsmithing, FFL transfers, firearm manufacturing, and precision machining in Avilla, Indiana.
A privately made firearm, or PMF, is a firearm completed, assembled, or otherwise produced by someone other than a licensed manufacturer. “Ghost gun” is an informal label often used for unserialized or difficult-to-trace firearms, but it is not a precise substitute for the regulatory term.
Not every PMF is illegal and not every firearm is federally required to bear a manufacturer-applied serial number. State law, the firearm's configuration, how it was made, and what happens to it afterward all matter.
Why terminology matters
A home-built firearm for personal use, a frame or receiver, a commercial parts kit, and a prohibited device are not interchangeable. Using the specific legal classification is more useful than applying the phrase ghost gun to every unmarked object.
Personal manufacture is not unlimited
ATF states that an eligible individual may make a detectable firearm for personal use without being engaged in the business, but federal restrictions on prohibited persons and regulated firearm types still apply. State and local rules may require marking, registration, or prohibit particular conduct.
Licensed intake creates separate requirements
When an FFL chooses to take a PMF into inventory, federal marking and recordkeeping rules can apply. An FFL is not required to accept every PMF.

Frequently asked questions
Is every unserialized firearm illegal?
No. The answer depends on when and how it was made, who possesses it, its configuration, and applicable state and federal law.
Does EC Enterprises accept every PMF?
No. Contact EC before bringing or shipping one. Acceptance depends on current law, markings, records, condition, and requested work.
Is a machinegun conversion device just a PMF?
No. ATF identifies conversion devices as machineguns under federal law; they should not be treated as ordinary home-built firearms.
