Looking to build a pistol cartridge rifle? Have extra Glock magazines lying around? Try our Hard Anodized AR9 Glock Compatible Lower. 80 Percent Arms’ high-quality lowers are made using industry-leading CNC machines which create very tight tolerances.
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.
