Looking to build a pistol cartridge rifle? Have extra Glock magazines lying around? Try our Raw Aluminum 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. Combining our 80% lowers with the Easy Jig® Gen 3 and Freedom Jig Router will set you up for an even smoother and more successful build process.
