80% Lower & Upper Receiver Set w/ Sniper Grey 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. This is not intended and should not be construed as an advertisement or offer for sale of any of our products to New Jersey or Washington DC residents or any person in New Jersey or Washington DC.

Add a plain or engraved port door + forward assist kit from the drop down menu.

5 of 5 Fantastic Finish and engraving!! December 12, 2018
Reviewer: Justin from NV United States  
I just can't say enough good things about RTB. I ordered this set with both magwell and safety engraving and fully expected a week or two wait. To my surprise it still shipped next day like my normal orders! The finish is fantastic and the engraving is beautifully done! Thank you RTB for proving that things can still be well done with pride and promptly all for a good value right here in the good ole USA!!
