| Content | 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.
See the manufacturer's instructions here.
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.

With your receiver fabricated, you can install a lower parts kit and buttstock or brace, throw on an upper receiver of your choice, and hit the range in one day. | The patented Easy Jig® Gen 3 Multiplatform™ replaces the Gen 2 as the world's easiest to use, fully universal, 80% lower jig capable of finishing AR-15, AR-9, AR-45 and DPMS gen 1 pattern .308 80% lower receivers without the need for any additional adapter pieces. The jig converts between AR-15 and .308 by quickly adjusting the rear buffer support, making it easier than ever before to mill any platform you desire.
The Easy Jig® Gen 3 is the culmination of our years of experience gained from manufacturing the world’s first router jig and the best selling 80% lower jig in history, the Easy Jig® Gen 1, and then the revolutionary Easy Jig Gen 2. We thought through every possible detail to improve the user experience with Easy Jig® Gen 3 and took into account hundreds of suggestions from our customers. No detail was too small to be overlooked. The result is quite simply the finest 80% lower jig ever produced. This is the first jig in the world to account for tolerance variances across any possible lower, allowing them to mount at their true datum points. An all-new mounting surface with our "Trident" front pin completely eliminates yaw, pitch, and roll of the lower while in the milling process. We invite side by side comparison to any other 80% lower jig on the market, nothing else compares.

Made in USA | This Elite Builder 80% Lower Jig is DISCONTINUED.
Compatible with our Forged 80% Lowers and our Premium Fire/Safe Marked Billet 80% Lowers! Other manufacturers' billet 80% lowers may be compatible with the Elite Builder 80% lower jig, provided their lower receiver design adheres to mil-spec specifications. However, we cannot guarantee that other manufacturers' lowers, including 9mm calibers, will absolutely fit into the jig without modification unless they meet mil-spec parameters.
The Elite Builder 80% Lower Jig and tool kit combo is the key to cutting and drilling multiple 80% lower receivers for the AR-15 or AR-9 without losing efficiency or accuracy. Made from hardened steel plates, the Elite Builder jig can machine any standard (mil-spec) forged, billet, or polymer receiver without breaking a sweat, with results as accurate as one-thousandth (0.001”) of an inch.
You can also now choose to include the enhanced drill plate to further make it easier for you to drill and hollow out your fire control group pocket.
PLEASE NOTE: Tooling for this jig is optional. You'll need to select whether you would like accompanying tooling with your jig.
