80 Percent Arms Universal 80% AR-15 Easy Jig



The universal fit Easy Jig® is a patented device that makes machining your 80% lower easier, faster, and safer. The Easy Jig allows you to complete an 80% lower in about 1/3 the time it takes to complete a lower on an old style drill press jig. This jig is easy enough for a caveman to use. It definitely lives up to its name. You also save money on tools. You do not need to own a drill press, mill, or any measuring tools to use the Easy Jig. The Easy Jig is built like a tank (weighs over 8 lbs) and can be reused for dozens of lowers. For those planning to use their jig for 20+ lowers, we offer optional hardened steel drill bushings in both side walls.

Easy Jig highlights:

Universal Fit

    • Fits both forged and billet AR-15 lower receivers from every known manufacturer except for New Frontier.


    • 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


    • 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 Easy Jig will hold tight 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 (about 75% less expensive).


    • 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 under 1 hour (vs of 3 hours for the old drill press method)


    • The Easy Jig can be used to make dozens of lowers
    • Components are Type III hard anodized for extra wear resistance
    • Hardened steel drill bushings are available as an option

Packaging August 23, 2016
Reviewer: Daryl Krenmueller from Harwood, TX United States  
Product is of good quality and well worth the price.
However the package arrived damaged. Only the packaging though. I hold the USPS accountable rather than RtBA&S.

Worth every penny July 1, 2016
Reviewer: Anonymous Person from United States  
I am very impressed! It's easy to assemble, and the tolerances are tight. Most are within 10 thousandths or less! The depth was about 20 too shallow, so I had to go a bit deeper. It probably would work, but I'm just a perfectionist. I did scratch the inside a bit, but it's not noticeable assembled. I used the recommended Ridgid router, and it was really fun. Make sure to have a vacuum, too. Chips go everywhere!
