Upper Receiver and Barrel

The billet aluminum AR-15 pistol caliber upper receiver with a hardcoat anodized black finish forms the core of the front end for the AR-9 platform. The 8.3-inch medium profile steel barrel brings a nitride finish and a 1-10 twist rate to the 9mm chamber, threaded at 1-2x28. This upper operates on a direct blowback system, meaning there is no gas tube or gas block present or required on this upper. The 7-inch slim freefloat smooth M-LOK handguard in black surrounds the barrel along the compact forend with M-LOK slots along the handguard surfaces for accessory attachment.

Muzzle Device

The 9mm pass-through flash can in black threads onto the 1-2x28 muzzle end of the barrel. The included black crush washer seats at the barrel shoulder and completes the muzzle hardware for this kit.
