Looking to build a pistol cartridge rifle? Have extra Glock magazines lying around? Try our Bead Blasted AR9 Glock Compatible Lower. 80 Percent Arms’ high-quality lowers are made using industry-leading CNC machines which create very tight tolerances.
To learn whether you should Anodize or Cerakote the lower, see our blog here!
Take advantage of the expansive AR15 aftermarket support in a pistol caliber platform. Our AR9s accept any standard parts that are compatible for an AR15 lower receiver!
We manufacture our 80% lower receivers with US-sourced aerospace grade 6061 aluminum. The material is more durable, resistant to corrosion, and yet much easier to mill than any other alloy.
Can’t decide between an AR15 or AR9? Check out our blog to help you decide!

*Please Note: Due to the bead blasting, the lower is not meant to be left as is and requires top layer finishing. Ensure that you purchase an upper receiver that has LRBHO feature built-in. See our blog post here that explains more about LRBHO.
