Yankee Hill 110 Flat Top Upper Receiver 5.56x45mm NATO

Description

The Yankee Hill 110 is a stripped flat top upper receiver for building or upgrading an AR-15 rifle. Its forged 7075-T6 aluminum construction, M4-style feed ramps, and standard component compatibility provide a practical foundation for a custom setup.

This receiver accepts standard upper receiver parts and Mil-Spec lower receivers. It is supplied without the forward assist or dust cover assembly, and completing the upper requires additional components including a charging handle, barrel, handguard, gas system parts, muzzle device, and bolt carrier group.
