The Luth-AR AR-15 A3 Upper Receiver Parts Kit brings together the essential forward assist and ejection port components needed to complete a mil-spec AR-15 upper. Centered around a robust ejection port cover assembly and matching forward assist, this kit is designed to drop into compatible A3-style receivers and restore reliable function with straightforward installation.

This kit is well suited for new AR-15 builds as well as refurbishing a well-used upper that needs fresh small parts. Builders and armorers will appreciate having the ejection port cover, rod, C-clip, spring, forward assist button, spring, and pin packaged together so nothing is overlooked during assembly. It is a practical choice for range rifles, training carbines, or general-purpose AR-15s where dependable operation is the priority, backed by Luth-AR’s experience in AR platform components.
