Description
Luth-AR UR-01-E3-S is a stripped A1 Slick Side upper receiver for .223 Rem/5.56 NATO. It is machined from 7075-T6 aluminum forgings to final dimensions, with early-style carry handle contours and an A1-pattern rear sight housing. This slick-side design eliminates the shell deflector and forward assist, and it does not use M4-type feed ramps found on many current-production flattop uppers.
