Ghost GUNS: Tactical K Training and Firearms Policy...Let's Take a LOOK

Privately made firearms—often called ghost guns—are weapons assembled by individuals from unfinished parts, kits, or 3D printed components. Traditionally, these firearms did not carry serial numbers and could be built without a background check, making it difficult for law enforcement to trace. This lack of traceability is what earned them the nickname “ghost guns.”

In recent years, the federal government has taken significant steps to regulate these firearms. According to multiple legal analyses and Supreme Court updates, ghost guns are now treated much more like commercially manufactured firearms under federal law. The Supreme Court upheld an ATF rule requiring that key components—such as frames and receivers sold in kit form—must have serial numbers and can only be sold by licensed dealers who conduct background checks.

This means that while it is still legal for individuals to build their own firearms for personal use, the parts and kits used to make them are now regulated. Purchasing a kit that can be “readily converted” into a functional firearm generally requires the same legal steps as buying a complete gun.

• Building your own firearm is still legal under federal law, as long as you are not prohibited from owning a firearm.

• Ghost gun kits and unfinished receivers are now regulated, requiring serialization, licensed sales, and background checks.

• State laws vary, and some states impose additional restrictions.
