Yankee Hill Machine Co AR-15 Stripped Upper Receiver – Mil-Spec Forged 7075-T6

The Yankee Hill Machine Co AR-15 Stripped Upper Receiver is a mil-spec forged upper designed for standard AR-15 lower receivers chambered in 5.56 NATO or .223 Remington. This stripped upper provides a solid foundation for custom builds, accepting standard AR-15 barrel nuts, handguards, and bolt carrier groups. The M4 feed ramp design ensures reliable feeding with modern ammunition.

Forged from 7075-T6 aluminum and finished with a hard-coat anodized Type III coating, this upper is built to mil-spec dimensions for compatibility with all standard AR-15 components. The flat-top design features a full-length Picatinny rail for optics mounting. Ships as a stripped upper receiver only—requires barrel assembly, bolt carrier group, charging handle, and handguard for completion. No gunsmithing required for assembly with standard AR-15 tools.
