Wanting to make the dive into building your own firearms, but aren't sure where to start? You've came to the right place. Not everyone has powertool or gunsmithing experience, and tackling both at once for a new project can seem a bit daunting. So we've made things as easy as possible for you to get started, but everything you need in one simple package. With a lower included, all you need to do is turn your router on, and get milling. It's really that easy. The threaded bolt catch screw that is required with our .308 lowers does not come with our lower. However, it does come standard in our .308 Lower Parts Kit. Here's what comes in the Starter Kit:
  • (1) 80% Raw  308 Lower
  • Easy Jig® GEN 3 Multi-Platform Jig (Handheld Router Compatible)
  • Easy Jig® Official Tool Kit, which includes:
    • Solid Carbide End mill
    • Optimized Fluting for Aluminum
    • Extremely Rigid Support
    • Direct-Thread to your Router
    • Longer Lasting, Averaging 5-7 Lowers per bit for Experienced Users
    • Made in the USA

LOWER FEATURES:
  • Full mil-spec part compatibility ensures maximum rifle customization
  • Withstands the harshest punishment from any situation using ultra-tough design, precision machined from aircraft-grade billet aluminum for superior strength.
  • Broached, flared mag well aids with faster, easier magazine reloads
  • Heavy-duty, integral trigger guard enables winter use with gloves
  • Unique, breakthrough design for easy bolt catch installation with a regular punch eliminates need for an expensive, special tool
  • Rear takedown lug pocket completed
  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.

For our customers who want it all - this is your kit! Purchase everything you'll need from us to quickly and easily finish AR-15 and AR-308 80% Lower Receivers.

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
