Faxon Firearms Enhanced Forged Assembled Upper Receiver Black

The Faxon Firearms Enhanced Forged Assembled Upper Receiver is a precision-machined component built for shooters who demand tighter tolerances and refined action in their AR-platform rifle. Built from 7075-T6 forged aluminum and finished with Type III hard coat anodizing, this upper receiver handles intermediate cartridges reliably and comes ready to pair with your bolt carrier group and charging handle. Faxon's factory blueprinting and honing process ensures smooth bolt carrier movement and consistent performance on the range or in the field.

What sets this upper receiver apart is attention to detail that shows. Faxon trues the receiver at the factory—a step many builders skip—and precisely hones the bore to eliminate friction and binding. The lug tolerances are held tighter than mil-spec, meaning your upper will lock up solid and stay that way. The shell deflector is hollow-ground for weight savings without sacrificing function, and the manually engraved T-marks stay visible even after coating, giving you reference marks that last the life of the rifle.

At just 6.88 ounces, this assembled upper includes the forward assist and dust cover you need to run the gun straight out of the box. It won't work with .458 SOCOM or other large-bore rounds, so stick with standard rifle calibers. You'll still need to source a bolt carrier group and charging handle to complete your build, but Faxon has already done the heavy lifting on precision machining and surface finishing.

Frequently Asked Questions

What calibers will this upper receiver work with?

The Faxon Enhanced Forged Upper is compatible with all intermediate cartridges (.223 Remington, 5.56 NATO, .300 Blackout, and similar). Faxon does not recommend use with .458 SOCOM or other large-bore rounds, as they may not function reliably in this intermediate upper.

Do I need to buy anything else to use this upper?

Yes. This upper receiver comes assembled with forward assist and dust cover, but you'll still need to source a bolt carrier group and charging handle to complete your rifle build.

What makes the factory blueprinting and honing process matter?

Blueprinting trues the receiver to tighter specifications than standard mil-spec, and honing smooths the internal bore to reduce friction on the bolt carrier group. The result is a more reliable cycling action and tighter tolerances overall—details that add up to better performance and longevity.

Will the T-mark engravings stay visible?

Yes. Faxon manually engraves the T-marks deep enough that they remain visible even after the Type III hard coat anodizing process, giving you lasting reference marks on your upper receiver.
