One Horse LLC OH-UR01 AR15 A3 Stripped Upper – In the White
The One Horse LLC OH-UR01 Stripped Upper Receiver (850078799340) is the perfect blank canvas for the custom builder who wants total control over their rifle’s final appearance. Provided "In the White," this receiver comes directly off the CNC machine without an anodized or Cerakote finish. This is ideal for builders planning a custom color match, specialized Cerakote project, or a unique polished aesthetic. Despite its raw finish, this is a premium A3 flat-top component, precision-machined from a 7075-T6 aluminum forging for maximum structural integrity.
Proudly 100% American-made, the One Horse OH-UR01 follows strict Mil-Spec dimensions to ensure seamless compatibility with standard AR-15 lowers, handguards, and bolt carrier groups. As a stripped unit, it provides the foundation for you to choose your own forward assist and ejection port cover assembly. Whether you’re building a high-performance competition rig or a unique "one-of-one" custom carbine, this "In the White" receiver offers the professional-grade tolerances and American craftsmanship necessary for a reliable, high-tier build.
Note: This receiver is "In the White" (Raw Aluminum). It is highly recommended to apply a protective coating (Cerakote, Anodizing, etc.) before final assembly to prevent oxidation and ensure long-term durability.
