Easy Jig highlights:

  • Easier
    • Built in drill/end-mill depth gauge for the trigger and rear-shelf pockets
    • Eliminates the need for expensive measurement tools
    • Quick verification of depth setting – eliminates slippage issues that can ruin parts
    • Eliminates constant measuring to determine depth while milling
  • Safer
    • End-mill downward force can’t separate the drill press taper chuck
    • It is safer to move router by hand than to move the jig around on a drill press
  • Uses Common Hand Tools
    • The .308 Easy Jig is designed to hold tolerances using a common hand-drill
    • No drill press is required, milling is done with a router
    • Routers are much more portable than a drill press, easily borrowed from a friend
    • Routers are made for cutting pockets using a template
    • Routers are cheaper than a drill press.
  • Faster
    • Pocket drilling requires 10 holes drilled once – Traditional jigs require 42 holes to be drilled once, precisely aligned and clamped, then re-drilled to a larger diameter
    • Trigger pocket can be cut in 6 to 11 passes vs 25 passes required with a drill press
    • Router cuts pockets 5-6x faster
    • Hand-drilling the trigger group/safety selector holes is faster to setup
    • Lower can be completed in 1 hour (instead of 3 to 8 hours for the old drill press method)
  • Durable
    • The Easy Jig can be used to make dozens of lowers
    • Components are Type III hard anodized for extra wear resistance

The 80% Arms universal drill press AR-15 jig consists of 5 individually replaceable plates that show you where to drill or mill your lower. We recommend it as a more cost effective option for more experienced users who already own a drill press. For those looking for the simplest, fastest system to complete a lower, we highly recommend our router based Easy Jig® system. Our universal drill press 80% AR-15 jig makes finishing your 80% lower at home with a drill press or mill much easier. Every part of this drill jig is reusable and can be used to make dozens of lowers. This AR-15 jig is NOT compatible with our .308 lowers or Easy Jig® tool kit. *Please note, the standard finish for this jig is silver, not anodized gray.  *We guarantee our Gen 1 AR-15 Drill 80% Lower Jig Press will fit all forged and billet AR-15 lowers except for New Frontier Armory, Iconic Industries, and lowers with a Ambidextrous Bolt Release.

80% LOWER REPLACEMENT PROGRAM: IN THE REMOTE CHANCE YOU MAKE A MISTAKE WHILE USING AN 80% ARMS JIG THAT DAMAGES YOUR 80% ARMS LOWER, WE WILL REPLACE YOUR LOWER AT A 50% DISCOUNT OFF OF THE LIST PRICE.

This jig is NOT compatible with an AR9 lower due to the sidewall dimensions, and it to be used with AR-15 only.

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.

What’s Included

  • (2) Side plates with drill bushings
  • (5) Template plates for fabrication
  • (1) Instruction manual
  • (1) Set of drill bits (selectable option)
  • (1) Set of end mill bits (selectable option)

What’s Required

  • Drill Press
  • Drilling Vise
  • Machining Oil
  • Eye Protection
  • Ear Protection
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.
This jig is compatible with our Forged 80% Lowers. Our Premium Fire/Safe Marked Billet 80% Lowers are not compatible with this 80% lower jig. Other manufacturer's billet 80% lowers may compatible with this 80% lower jig, provided their lower receiver design adheres to mil-spec specifications. Looking for the perfect affordable alternative to the expensive and more complicated metal jigs? You’ve come to the right place! This low-cost 80 lower jig by Polymer80 is a perfect choice, especially if you’re just planning on finishing a few AR15 or AR9 80 lowers. Why pay more, right? The Polymer80 RJ556U AR15/AR9 Universal Jig is an excellent addition to the very popular Polymer80 line. This Polymer80 jig wasn’t only designed for polymer lowers in mind. This 80 lower jig was created for compatibility with all mil-spec 80% AR15 lower receivers and AR9 80 lowers, whether they are polymer OR metal. The Polymer80 AR15 Universal Jig is designed with a super rigid long-fiber nylon composite, which will allow you to utilize the 80% lower jig up to 3 times. The  Polymer80 RJ556U AR15/AR9 Universal Jig is designed to provide a stable platform for milling, and therefore encompasses the entire AR15 or AR9 lower receiver. Other competing 80 lower jigs are typically more expensive and difficult to secure the 80 lower in the vise and more likely to damage the 80 lower receiver while milling.

The Polymer80 P80RJ556U AR15/AR9 Universal Jig includes:

  • 2 sided jig
  • 3 trigger guides
  • 9mm HSS end mill
  • 5/16ths drill bit
  • 3/8ths drill bit
  • 5/32nd drill bit

Example Tools Needed:

Extremely expensive or high-end tools are not required to use this jig to finish your lower.  All of the suggested tools mentioned below can be utilized for other popular Polymer80 receiver projects, including .308 80 lower receivers and 80% Glock® compatible pistol frames, so it’s easy to justify the expense!
  • Vise For Drill Press - 6” inch jaws
  • Drill Press -1850-2250 RPM
  • Digital Calipers
  • Dremel Bit #9904
  • Level
  • Round Machinists File
  • Non-marring vice jaws
  • Lower Receiver Vice Block
  • Upper Receiver Vice Block
The complete list of suggested tools can also be found in the instruction guide What are you waiting for?  Your build awaits!
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.
