80% Lower & Upper Receiver Set w/ Tungsten Cerakote and Engraving Option


The upper rear lug will not fit completely into the rear pocket of the lower until the lower is completely machined and finished by the end user. All of the jigs that we offer will accomplish this. This also allows you to custom fit your upper and lower with no wobble.

Upper Receiver Specs:

  • Machined from 7075 T6 Forging
  • Mil-Std 1913 Rail for mounting optics and accessories
  • Machined for use with barrels that use an M4 barrel extension

Lower Receiver Specs:

  • 80% Machined (Just needs trigger and safety well machined)
  • 7075 Aluminum
  • T6 Heat Treated
  • Magwells are flared and broached
  • Optional safety markings on both sides
  • Cerro Forge (Key hole may or may not be machined off)

Please note: Some states may not allow you to legally manufacture a firearm without a serial number (like the state of NJ and Washington DC). Please be sure to do your due diligence and make sure you are following your state and local laws before attempting to manufacture a firearm.

5 of 5 It's better than you're hoping for... October 13, 2020
Reviewer: Kenneth from USA  
I originally bought a few different 80% sets from the few different companies I had to shop at to get my jigs and all of my parts... the RTB stuff was BY FAR the best quality. The set fit together as a matched set should (other companies didn't), tolerances were perfect. The engraving is great too! I was worried it wouldn't be deep enough that it could be seen if I cerakoted over it which is what I initially planned on doing... but it is/was and on this tungsten it all ended up looking so good I decided to leave it exactly as it came. I honestly couldn't be happier with this set and won't buy anywhere else from now on. Thanks RTB!
