Description

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.

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

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
