Luth-AR A3 Upper Receiver Parts Kit Black

Building or maintaining an AR-15 upper receiver requires reliable, properly engineered components—and the Luth-AR A3 Upper Receiver Parts Kit gives you the small parts that keep everything running. This black-finished kit bundles the ejection port cover assembly and forward assist components into one convenient package, so you're not hunting down individual pieces from different suppliers. Whether you're assembling a complete upper, replacing worn parts, or stocking a spare kit, these Luth-AR components are built to work without surprises.

The A3 Upper Receiver Parts Kit includes everything needed for the ejection port and forward assist systems: the cover itself, ejection port rod, C-clip, and spring, plus the forward assist button, spring, and pin. Each piece is finished in black and engineered to AR-15 specifications. For shooters who prefer to source their own parts rather than buying complete assemblies—or who need replacements—this kit eliminates guesswork about compatibility and quality.

Luth-AR has built its reputation on precision AR parts, and this kit reflects that attention to detail. It's a straightforward solution for the builder, gunsmith, or shooter who values knowing exactly what they're installing and having confidence that those parts will perform reliably downrange, at the range, or in the field.
