Combat Armory AR-9 Stripped Upper Receiver Black 7075-T6 The Combat Armory AR-9 stripped upper receiver is a black 7075-T6 aluminum component for an AR-9 configuration. It is the upper receiver body rather than a complete upper assembly, making the stripped designation a central part of understanding the product. The alloy and temper are identified by 7075-T6, while black is the stated color. AR-9 identifies the intended platform category; it does not establish universal fit across every receiver, bolt or magazine arrangement sold under that label.
