AR-15 Ejection Port Dust Cover Assembly (Gen 3) (Cerakote Blue) (Discontinued)

Designed for the discerning AR-15 builder, this AR-15 Ejection Port Dust Cover Assembly (Gen 3) provides a robust solution for maintaining ejection port integrity. Manufactured in the United States of America, it is constructed from T6 6061 Aluminum, offering a balance of strength and corrosion resistance. The assembly is finished in Cerakote Blue, a durable coating that protects the metal while providing a distinct visual accent on your upper receiver. This specific unit is recommended for use with Billet Uppers Only, ensuring proper fit and function for those building from billet components rather than forged receivers.

The Gen 3 design incorporates an adjustable set screw, allowing for precise alignment of the dust cover’s opening and closing action. This adjustability is critical for ensuring the cover operates smoothly without binding or excessive play, which contributes to the overall reliability of the ejection port mechanism. The kit is complete, including the dust cover plate, the actuating rod, the return spring, and the retaining clip. This comprehensive inclusion means you have all necessary hardware for a direct replacement or upgrade without sourcing individual components separately.

Weighing in at just 0.3 oz, this assembly is ultra lightweight, adding negligible mass to the upper receiver while delivering full functionality. The .223 Calibre designation confirms its compatibility with standard AR-15 platforms chambered in this common round. The included L-shaped hex key facilitates the initial installation and subsequent adjustments of the set screw. For builders prioritizing precision fitment and US-made quality, this Gen 3 dust cover assembly delivers the necessary performance and aesthetic detail required for a high-end build.
