Luth-AR UR-01-E3-S A1 Stripped Upper AR-15 .223/5.56 Black Hardcoat Anodize

The Luth-AR UR-01-E3-S Slick Side A1 stripped upper receiver is a retro-style AR-15 upper made from 7075-T6 aluminum forging with a black hard coat anodized finish, designed for use with .223 Remington and 5.56 NATO barrels. It features correct early-style A1 carry handle contours with housing for an A1-pattern rear sight and is configured without several later AR-15 upper receiver features.

• Slick-side A1 upper with integrated carry handle
• 7075-T6 aluminum forging, black hard coat anodized
• No shell deflector, forward assist, dust cover, or M4 feed ramps

This stripped upper suits period-inspired builds or lightweight custom AR-15 projects in .223/5.56. Its combination of classic A1 styling and modern manufacturing offers a solid foundation for a complete upper assembly.
