Picking the right upper and lower for your custom AR-15 build can be a challenge. So, we put together two high-quality matching billet receivers to help you get started.

Made from 6061-T6 aluminum, both the stripped upper and the 80% lower receiver are made to be lightweight but tough. We've thrown in a dust cover and forward assist assembly to get you started -- now you can pick all the custom, upgraded components you want to build a custom, quality AR-15!

Upper & Lower Receiver Combo Features:

  • Includes M4 upper
  • Includes 80% lower
  • Matching anodized finish
  • Cut from 6061-T6 Aluminum
  • Forward assist and dust cover included
  • Compatible with all mil-spec AR-15 parts

How to Finish Your AR-15 80% Lower

Cutting and drilling your 80% lower to make it functional requires an AR-15 jig. We recommend the Elite Builder Jig, available here -- it's capable of finishing all three lowers included in this bundle. Follow these detailed, step-by-step instructions to fabricate your 80% lower using the Elite Builder Jig.

Assembling Your Upper and Lower

Once your lower is fabricated, it's time to assemble it. You'll need an AR-15 lower parts kit, available here, and a buffer tube kit. Follow our step-by-step picture guide for installing your lower parts kit and buffer assembly.

To assemble your upper receiver, follow our video guide!
