Yhm Ar-15 Stripped Upper Receiver

The Yhm AR-15 Stripped Upper Receiver from Yankee Hill Machine Co is a precision-forged aluminum component engineered for AR-15 platform builders and armors who demand mil-spec performance without compromise. Stripped uppers are the foundation of any custom AR build, providing the critical interface between lower receiver and barrel assembly while maintaining tight tolerances essential for reliability and accuracy downrange.

This receiver is machined from 7075-T6 aluminum forgings, the same material specification found in military small arms platforms, delivering superior strength-to-weight characteristics compared to lower-grade alloys. The M4-style feed ramps are cut to MILSPEC geometry, ensuring reliable chambering across all modern 5.56 NATO and .223 Remington ammunition. A hardcoat anodized matte black finish provides corrosion resistance in field conditions while resisting reflectivity during tactical operations. Interior surfaces are coated with dry film lubricant at the factory, reducing friction and extending component life under sustained fire.

This stripped upper is ideal for gunsmiths, law enforcement armorers, military personnel, and serious sport shooters building rifles to their exact specifications. Whether you're assembling a duty rifle, competition platform, or precision training build, this component provides the structural integrity and precision machining expected of a quality manufacturer. YHM's receiver engineering is trusted by end-users who understand that the upper receiver must perform flawlessly under demanding conditions—from patrol duty and tactical training to long-range precision shooting.

AR-15 stripped uppers require no serial number in most jurisdictions when sold without a complete rifle configuration, making them accessible components for builders. This receiver's compact dimensions and half-pound weight integrate seamlessly into any AR platform configuration. Yankee Hill Machine has maintained a reputation for manufacturing reliable AR components that withstand repeated field use, making this upper receiver a practical choice for dedicated shooters planning long-term builds.
