Luth-AR UR-01-E3-S A1 Stripped Upper Receiver

Luth-AR A1 Stripped Upper Receiver

The Luth-AR UR-01-E3-S represents authentic AR-15 heritage in a precision-machined upper receiver. Built from 7075-T6 aluminum forgings and finished to exacting specifications, this stripped upper delivers the classic lines and functionality of early-pattern AR-15 rifles.

Key Features

• 7075-T6 Aluminum Construction: Lightweight yet durable forged aluminum machined to final dimensions
• A1-Pattern Design: Correct early-style carry handle contours with period-accurate rear sight housing
• Slick Side Configuration: Eliminates shell deflector and forward assist for authentic appearance and reduced weight
• Mil-Spec Compatibility: All attachment points finished to current military specifications for seamless integration with standard AR-15 components
• Black Hardcoat Anodize: Durable finish resists corrosion and wear

Important Considerations

This is a stripped receiver—charging handle dust cover and rear sight components are sold separately. As a period-accurate design, this upper receiver features original-pattern feed ramps rather than the M4-type ramps found on modern flattop uppers. This distinction matters if you're building a historically correct rifle or prefer the classic A1 platform.

Perfect for builders seeking authentic early-pattern AR-15 aesthetics or those restoring vintage configurations.
