The ultimate AR9 rifle, now in a convenient build kit.
Chasing maximum accuracy with the 9mm cartridge was never easy -- until now. We're pairing one of the most popular AR9 upper assemblies we've sold with an AR build kit, allowing you to more easily complete your 16" 9mm rifle, for less.
Up top is a heavy-barreled, side-charging upper that affords 200 meters of tack-driving performance, with a heavy barrel made to take the abuse of +P ammo for even more range and power.
Below, you're getting the gold standard: A mil-spec AR-15 lower parts kit, 9mm buffer assembly to reduce felt recoil, and an M4 buttstock.
How to Assemble Your AR9 Lower
NOTE: Lower is sold separately (9mm 80% lowers available here!).
Follow our detailed instructional guide here: How to Install The AR-15 Lower Parts Kit.
This kit's lower is assembled just like any other standard AR-15 lower receiver assembly.
