What is an 80% Lower?
An 80% lower is the unfinished frame of a firearm. It is the last point before the goverment considers it a firearm. The 80% lower is NOT considered a firearm.
Is an 80 percent lower legal?
You are building and finishing the weapon yourself for yourself. This makes it legal under the Gun Control Act of 1968. This is on the ATF’s website https://www.atf.gov/questions-and-answers/firearms-qas Make sure to do your own research with federal, state, and local laws before purchasing.
Can I Build an 80% Lower as a gift to my friends or family?
No, if you build one it has to be for yourself. You must be a licensed manufacturer to build the firearm for someone else.
If I purchase an 80% kit will I need more parts to finish my firearm?
No you will not need to purchase more parts but certain tools can make the process easier.
Do I need to put serial numbers on the finished 80% lower?
A licensed Manufacturer has to seriallize all firearms they make. You making a personal one is not required but you may want to put markings so it can be distinguished if it is ever stolen.
What can Law Enforcement do if they see me using my completed firearm?
As long as you are using it legally, nothing. IF they are like our local law enforcement they are gun people as well and might want you to talk about it. But if I had to guess, it would be more curiosity than anything else.
Can I make an SBR / Full Auto / other weapon?
If I am not allowed to purchase a firearm through traditional means can I own an 80%?
NO. To make your own firearm you must be legally allowed to own and purchase a firearm.
Do You Ship to New Jersey or California?
Not anymore. Don't like it? fire your governor.
How to finish a receiver.
What tools work best for finishing a receiver?
We suggest that you have a drill press and a x y table with a vice to finish the lowers. There are some that say it can be done with a rotary tool, but it is not suggested. You can also use a milling machine, or rent time at a local machine shop. You may also want to have a few files to clean up the lower when you are finished.
What size drill bits and milling bit are suggested for finishing the AR-15 lower?
5/16" End Mill (For milling out fire control pocket) 5/16" Drill Bit (Trigger hole) 3/8" Drill Bit (Saftey selector switch) 5/32" Drill Bit (Trigger pin and Hammer pin)
