We're excited to bring you one of the new additions to our line of 9mm AR pistol build kits. This kit starts with an upper assembly prebuilt with a 10.5" nitride-coated barrel. Surrounding the barrel is a 12" slanted M-Lok free floating handguard. For extra attitude, the muzzle is topped off with a fluted flash can.
You also get an upgraded lower parts kit instead of a standard one. This one comes with an upgraded trigger and a Magpul MOE grip and an enhanced, polished trigger!
Finally, you have the option to choose our 9mm 80% lower receiver. Please note, this lower's mag well is cut to accept factory and aftermarket 9mm Glock (not Colt) magazines.
