Luth-AR UR-05AA1 A1 Ejection Port Cover Assembly

The Luth-AR UR-05AA1 A1 Ejection Port Cover Assembly is a complete drop-in kit for A1-pattern AR-15 and M16 upper receivers. Built for retro and clone builders, this assembly supplies every component needed to correctly install and secure the ejection port cover on a fixed-carry-handle or A1-style upper.

The set includes the A1 ejection port cover itself, a stainless steel spring, the rod, and the retention clip - all the hardware required to keep the dust cover functioning properly and prevent debris and fouling from entering the action during carry and shooting. The cover carries a heavy phosphate coating for a classic military finish that matches original A1-spec components.

Whether you are restoring a classic clone, finishing a retro AR build, or simply replacing a worn or missing dust cover assembly, this Luth-AR kit provides a reliable, correct-pattern solution for your AR-15/M16 platform.
