F-1 Firearms UX-9 Skeletonized 9MM Upper Receiver

About this product

The F-1 Firearms UX-9 Skeletonized 9MM Upper Receiver serves as the primary housing for the bolt carrier group, charging handle, and barrel assembly on a 9MM AR-platform firearm. This component provides the structural foundation for these parts, ensuring their proper alignment and function within the rifle system. Its skeletonized design reduces overall weight, which can contribute to a lighter firearm build, potentially improving handling and reducing fatigue during use.

Key details

• This upper receiver is constructed from 7075 billet aluminum. This material choice provides a balance of strength and machinability, common for firearm components that require durability without excessive weight.
• The surface of the receiver features a Type III Class 2 hard coat anodized finish. This type of anodizing creates a hard, corrosion-resistant layer on the aluminum, protecting the component from wear and environmental exposure, contributing to its longevity.
• The receiver weighs 7.2 ounces. This weight specification indicates a relatively light component, which is a direct benefit of its skeletonized design. A lighter upper receiver can reduce the overall weight of a firearm, potentially enhancing maneuverability and reducing the burden on the user during extended periods of carry or firing.

Fit and compatibility

This is a 9MM upper receiver. Buyers should consult the manufacturer's documentation to confirm compatibility with other components such as barrels, bolt carrier groups, and lower receivers for a complete and functional firearm assembly.
