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.

Quality HSS Bits

The jig’s only as good as the bits you use it with. Choose to add on the optional tooling - quality industrial-grade HSS (high-speed steel) drill bits and end mill bits to cut through all that aluminum in no time. All you need to complete your receiver blank is a basic drill press and about two hours’ time. The tool kit includes:
  • (1) ⅜ Drill Bit - 5”
  • (1) 5/32 Drill Bit - 3”
  • (1) ⅜ Short End Mill - 3”
  • (1) 5/16 Short End Mill - 4”
  • (1) ⅜ Long End Mill - 4”

Jig Features & Specs:

  • Self-aligning jig requires no special fitting during setup
  • Compatible with any standard AR-15 or AR-9 80% lower
  • Black anodized finish protects against rust and corrosion
  • Pre-drilled holes for hammer, trigger, and safety pin holes
  • Reinforced steel template plates for completing multiple lowers
 
The Easy Jig® Gen 1 is a patented AR-308 80% lower jig that makes machining your 80% lower receiver easier, faster, and safer. Lower receivers finished with the .308 Easy Jig have a better finish and hold tolerances that could not be achieved using any other jig on the market today. You do not need to own a drill press or mill to use the Easy Jig®.  It truly makes finishing your lower receiver a simple process. On top of all this, it’s extremely durable and can be reused for dozens of lowers. This product is proudly made in USA. Fully compatible with our Black Anodized, Flat Dark Earth (FDE), or Raw 308 lowers.  The Easy Jig Gen 1 is NOT compatible with all other brands of .308 lowers. If you want full universal compatibility, please see our Gen 2 Easy Jig.  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

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.

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.

  • 5/16ths drill bit
