Product Description
The Luth-AR .223/5.56 Assembled Upper Receiver Assembly (SKU: FTT-EA1 / UPC: 859819007805) provides a complete, factory-assembled receiver foundation designed for custom AR-15, M4, and firearm builds. Precision-forged from 7075-T6 aluminum for ultimate structural strength, this upper receiver comes pre-installed with a factory ejection port dust cover assembly and forward assist mechanism, alongside a mil-spec aluminum charging handle.
Finished in a durable Type III Class 2 hardcoat anodized matte black coating, the FTT-EA1 features precision-machined M4 feed ramps to optimize cartridge feeding reliability with .223 Remington, 5.56 NATO, and .300 AAC Blackout barrels. The top MIL-STD-1913 Picatinny rail incorporates laser-etched T-markings for consistent optic, scope mount, and iron sight positioning.
Whether assembling a modern carbine, long-range precision rifle, or replacement upper receiver assembly, the Luth-AR FTT-EA1 offers tight tolerance pairing with standard mil-spec lower receivers, making it an ideal choice for custom armorer builds.
