Luth-AR Ejection Port Cover Assembly – AR-15/M16

The Luth-AR Ejection Port Cover Assembly is a direct replacement for worn, damaged, or missing ejection port covers on AR-15 and M16 upper receivers. This assembly maintains proper ejection port function, protecting the chamber and bolt carrier group from debris and contaminants when the rifle is not in use or between shots. It's a common maintenance part that restores factory function to uppers with broken or lost covers.

Machined from mil-spec materials with a black anodized finish, this assembly includes the cover door, C-clip, spring rod, and spring for complete installation. Installation is straightforward for shooters familiar with AR-15 assembly, requiring only basic tools and attention to proper spring tension and C-clip seating. The cover snaps open automatically during firing and closes manually when the action is not in use.
