What is an 80% Lower Receiver?

An 80% lower receiver is a piece of material (Aluminum) which has been partially completed to a certain point.  With readily available tooling from local hardware stores and the right techniques, the lower can be transformed into a working firearm.


Is an FFL required to build a firearm for personal use?

No. You are building the firearm for yourself for your own personal use which is legal under the Gun Control Act of 1968. This is on the ATF’s website under their FAQ page. You can see it here: 

It is not required to be transferred through a Federal Firearms License Dealer with all the federal paperwork like its finished counterpart, the completely finished lower receiver.  These factors make for easy purchasing for home gunsmiths and hobbyists for personal use.

 It is a good idea to mark your firearm somehow so that should it ever be lost or stolen you have a way to identify it and report its loss to your local law enforcement.

 Please check you're local and state laws.
