308 80% LOWER RECEIVER AND JIG SYSTEM – FLAT DARK EARTH

After two years of planning, design, engineering, and testing, we’re proud to introduce the industry’s first reinforced polymer receiver designed for the DPMS styled .308 in an 80% format. 308 80 lower receiver and jig system.

Our AR-10 jigs are designed with first-time builders in mind, so we have built-in safeguards to prevent common errors, drill bit depth guides, a manual, and tutorial videos to make the process even easier! With instructions and basic tools in hand, you can confidently complete your AR-10s lower in around one to two hours.

.308 80% Lower Receiver & Jig

Our .308 80% jigs provide you with the tools you need to complete that AR-10 clone or 700-yard bench rifle receiver. Choose the rugged Elite Builder Jig, fabricated from hardened steel with drill bushings, and confidently cut and drill your receiver for your lower parts kit, upper, and buffer system in a single afternoon.

Jig & Receiver Compatibility

These jigs last for long! One metal AR-10 jig can easily complete twenty or lowers without having to replace any plates from wear-and-tear. Want to spend as little as possible on your 80 percent lower .308 build? The polymer jig-and-lower combo kits come with both an AR-10 polymer receiver blank, the jig, and the bits!

Also, each of our stand-alone .308 jigs is made compatible with the popular DPMS LR-308 (gen 1)-type .308 80% lower receiver. These full-size receivers closely mimic the size and shape of the original ArmaLite-10 platform. Therefore, offers you the opportunity to build an accurate 7.62 NATO or .308 shooter from the ground up.

The .308 80% Lower Receiver  Design features:

  • Unique reinforced polymer design with solid core design
  • ATF compliant design
  • Beefed up buffer tube ring and ribbing across the entire upper surface area.
  • No-thread design on the pistol grip area.
  • Stiffened magwell, ultra-light design.
  • See the product page for additional parts list

Is it legal?

YES! The 308 unit is well within the defined parameters of a “receiver blank” defined by the ATF. Therefore, it has not yet reached a stage of manufacture that meets the definition of firearm frame or receiver found in the Gun Control Act of 1968 (GCA).

AR-308 Jig: What Comes With It?

The Polymer80 .308 jig includes all parts required for machining, including the polymer receiver blank itself! Purchasing a stand-alone jig like the Elite Builder also provides you with all components necessary to cut and drill your receiver blank:

  • (2) Side plates
  • (3) Top plate templates
  • (1) Set of HSS drill bits
  • (1) HSS end mill bit (center-cut)

Tools Required:

  • Drill press
  • Table-top vise
  • Cutting fluid

Other 308 80% LOWER RECEIVER AND JIG SYSTEM  color kits available:

While other jigs on the market require a router or milling machine, the Elite Builder’s HSS end mill bit is designed to allow you to cut the fire control cavity with plunge cuts, vertical cuts made with the end mill in a similar fashion as drilling the cavity’s pilot holes.

This is easily accomplished using a cross-slide vise that affords lateral movement.

In conclusion, with a cross-slide and press, you can complete your 308 80% LOWER RECEIVER AND JIG SYSTEM – FLAT DARK EARTH blank within two hours.

    I had looked all over and went to a couple of gun shows to try and find a specific firearm with no luck, I watched on gunbroker and within a short time I was able to find the firearm I was looking for. I was able to make the purchase with ease and at a better price than I was seeing elsewhere. I look foward to making purchases in the future. Thanks Christopher!!

  • Simon Peter

  • Diane Moore

    Excellent

  • Spyro MaGuy

    abslute perfection

  • Stephen

    i have purchased numerous lowers and have found no defects. I have also purchased the Jig and related supplies. The shipping is quick but would prefer FEDEX instead of US Mail. Where i live US Mail is not reliable. I look forward to my future builds.

  • Dale G.

    pros: the piece looks good, mill marks are fine.
    con: the anodizing is rough and spotty in places and rough like sandpaper in places

  • Daniel M.

    Ordered 2, shipped out next day and had them a few days later, with all the craziness I’m surprised it was that fast. Finish on these ar10 lowers is next to none, they look kick ass!! Will definitely be ordering more from P80GB

  • Christopher P.

    This isn’t the first one of these lowers I’ve purchased and I have to say that they are very well made and the aluminum is nice and hard. The finish is very even and no machining as well as the fit to my upper is perfect. Keep up the great work 5D. My kids hope to purchase a few before the ban.

  • samantha m.

    Super quick shipping! Look great! Can’t wait to finish them!
