80% Lower Jig Kits

The 80 lower jig kit is the easiest (and most affordable) way to build an AR-15 at home, legally and safely! With our jig kits, you can avoid the gun store prices, fees, taxes, and bureaucratic paperwork. The ATF says building your AR with an 80% lower and jig kit also means you don’t need to go through an FFL!

Includes necessary tooling and bits!

Our 80 lower jig kits are some of the most affordable and capable on the market! But affordable doesn’t mean cheap: Each jig kit has all the tooling you need to complete your 80 lower at home with basic hand tools and little to no knowledge!

Every kit includes an 80% Lower!

We’ve bundled in our quality, made-in-the-USA 80% lowers with each 80 lower jig kit so you can get everything you need shipped to your door for one low price, minus all the red tape, paperwork, transfer fees and FFL bureaucracy.

Want the most affordable kit? Grab the Easy Jig Gen 1 with a forged 80% lower. Want the fastest? The Router Jig PRO (includes a Premium Billet Lower!) is where it’s at.

Machining an 80 lower receiver is 100% legal in all 50 states, and you need no paperwork or background check to build at home for your own use! Be sure to check your local and state laws before building, too.
