Guntec USA AR-9 Stripped Billet Upper Receiver 9mm - Anodized Black

The Guntec USA AR-9 Stripped Billet Upper Receiver is a dedicated upper receiver machined from solid T6 6061 billet aluminum for builders running a 9mm Luger AR-platform pistol or rifle. Designed specifically for the AR-9 pattern, this upper provides the correct geometry needed to reliably feed 9mm ammunition in a pistol-caliber AR configuration.

The receiver carries a durable anodized black finish for corrosion resistance and a clean, uniform appearance across the entire part. It features a classic flat top upper receiver profile with an integrated Picatinny optics rail, ready to mount red dots, scopes, or back-up iron sights. As a stripped upper, it ships without a bolt, bolt carrier group, charging handle, or barrel installed - giving you the foundation to complete your build with the components of your choice.

Dimensions come in at 1.95 in tall, 3.80 in wide, and 9.40 in long, fitting standard AR-pattern lower receivers and handguards. Proudly made in the USA from quality T6 6061 billet aluminum, the Guntec USA AR-9 upper offers a rigid, lightweight platform for assembling a 9mm AR from the ground up.
