    Liberty 80% Lower Jig (AR-15/AR-9)

    You love to build guns. You’ve heard about building an AR from scratch using little more than a drill press. This is the toolkit to get it done: The Liberty AR-15 Jig is designed to eliminate the need for expensive equipment like a router or mill. It uses simple, tough-as-Hell machining templates that allow you to fabricate the AR-15’s forged or billet 80% lowers with nothing more than a drill press and vise. Of course, it does work just fine with any mill if you’ve got the equipment.

    PLEASE NOTE: Tooling for this jig is optional. You’ll need to select whether you would like accompanying tooling with your jig.

    How the Liberty 80% Jig Works

    The Liberty 80 Lower Jig takes a largely vertical approach to cutting your AR-15’s receiver for the lower parts kit. Using the provided drill bits, you’ll first remove a large portion of aluminum from inside the main fire control cavity by drilling various pilot holes. Quick and easy. The jig tells you how far down to drill. All you need to do is control the press.

    You’ll then use the end mill bits for light cutting and cleaning up the receiver’s walls before cutting a hole for the trigger. Lastly, reinforced drill bushings on the right side plate ensure your hammer, trigger, and safety pin holes are drilled perfectly through the receiver. No measurements required for these. Then you’re done! The whole process takes about 1 to 2 hours for first-timers.

     

    It’s All in The Bits

    The secret to the Liberty 80 Lower Jig isn’t just the plates, templates, and guides. The included bits are made from quality high-speed steel (HSS). These are commercial-grade bits that can eat through forged or billet aluminum in seconds, making fabricating multiple receivers as quick as it is simple.
