At least two national gun rights groups are contemplating lawsuits to challenge the new federal regulation on privately made firearms, or so-called “ghost guns.”
The final ruling, published by the ATF on Apr. 11, essentially expands the definition of a firearm to include partially complete and readily convertible firearm receivers (also called frames).
Once the ruling goes into effect, those receivers will be regulated just like regular firearms, subject to requirements such as serial numbers and background checks.
