Editor’s Introductory Notes: This is a three-part article.
Consult your state and local laws before buying any 80%-complete lower receivers.
Proceed with caution. Remember the eternal rule of machining: You can take metal away, but you can’t put it back.
I recommend buying the Easy Jig 3. Or, if you plan to complete a large number of lowers, then invest in a Ghostgunner 3. Once you’ve completed all of your lowers for your family, you will probably find a private buyer who is willing to pay you 90% or more of your purchase price for your Ghostgunner. The advantage to him will be that he is buying it with no paper trail.

With the 2020 presidential election just weeks away, it seems timely to revisit the subject of finishing an 80% complete AR lower receiver. There have been nice articles in SurvivalBlog relating to this subject in 2014 by JAG in 2017 by Tupreco, and in 2018 by Hugh Latimer. There are new laws and tools to discuss since these articles have been written.
What are we talking about?
An 80% lower receiver is an unfinished version of a stripped 100% finished lower receiver. It is not a firearm, it cannot be used to fire a projectile without significant machining operations, it doesn’t have a serial number, and it can be shipped directly to your home without a background check or going through a dealer who possesses a federal firearms license. There is no FFL transfer fee. You get the privilege of doing the mechanical work on this chunk of metal or plastic to make it a functional firearm.
Why bother?
It takes quite a bit of planning and time to complete this project. You will do research into materials needed including the 80% lower receiver itself, tools to do the machining, lower parts kit to make the lower fully functional, a barreled upper receiver, bolt carrier group and charging handle. You will read all the instructional materials that come with your jig and watch videos from the jig manufacturer and others who have kindly recorded their experiences and given their assessment of their project for your benefit. The cost of doing this is not insignificant. So, what do you get out of it? You have the basis for a very flexible firearm that has bypassed the usual paperwork trail; a firearm that has never been registered or purchased subject to a background check. You learn a new skill, not only to build this firearm, but you learn how to install and remove parts and repair and replace parts if something breaks or isn’t functioning. You will have pride in building a high-quality firearm that can last potentially for generations. You may be able to build a custom firearm not available commercially at any price.Continue reading“Finishing an 80% AR Lower Receiver – Part 1, by 2A Advocate”
