Product Overview

The Luth-AR Assembled Slick Side A1 5.56 NATO upper receiver is machined from 7075-T6 aluminum forging and finished in hard coat anodized black for durability. Built with early-style Slick Side A1 contours, it includes the A1 rear sight and ejection port cover assemblies installed while omitting the shell deflector and forward assist. It also does not use M4-type feed ramps, maintaining a period-accurate AR-15 / M16 slick-side configuration that accepts current AR-15 compatible components at standard mil-spec attachment points.
