It is forged from 7075-T6 aluminum and finished with a black hard coat anodized surface. The upper uses early-style A1 carry handle contours with an A1-pattern rear sight housing and comes with the A1 rear sight assembly and ejection port cover door installed, while omitting the shell deflector, forward assist, and M4-type feed ramps; charging handle components are not included.

• Slick-side A1 upper receiver for AR-15 builds
• 7075-T6 forged aluminum with black hardcoat anodized finish
• A1 rear sight and ejection port cover preinstalled

This upper receiver provides a classic A1 appearance while remaining compatible with current production AR-15 components in .223 Remington and 5.56 NATO. Its assembled configuration and retro slick-side design make it a practical starting point for traditional-style uppers.
