Do You Need a Special License for Buying or Owning an 80 Lower Jig?
Many people are apprehensive about buying the 80% jig because they feel like they might be asked for a license. Under federal law, the jig itself is not considered a firearm in any way. It is simply a kit that helps with building a firearm. As such, no license has ever been needed to purchase an 80 lower jig.
How 80% Jigs Work
The 80% jig is a collection of tools, measurements, and physical guides used to make a firearm on your own, allowing you to make your receiver functional. It is made of aluminum, and steel, and the jigs and parts are made specially to cater to the firearm being built, so be sure to purchase the right one for your particular rifle or pistol.
How AR-Type 80% Jigs Work
The difference between the 80% jigs and the AR-type 80% jigs is the type of firearm being made. The jig will come with its own parts and a drilling template for you to create the custom firearms you have in mind.
No Experience Necessary for Using 80% Jigs
The good thing about working with jigs is that you do not need a lot of experience to work on them. They are perfect for beginner gunsmiths who are just starting out on finishing AR-type firearms. The instructions are transparent and easy to follow, and you will also get a drilling template that you can use for your firearm. The only thing you need to know is the basics of firearm assembly.
Unparalleled Quality and Engineering
Made of heavy machined aluminum here in the USA, these jigs are designed to be used for years. Care is taken in every step of our manufacturing process, with extreme measures in our quality control process to ensure any 80% lower receiver you manufacture will be compatible with the full array of AR-15 or .308 equipment available on the market.
