AR-10 / LR-308 Ejection Port Dust Cover Assembly (Gen 3) (8.6 BLACKOUT)

Description

This Gen 3 Ejection Port Dust Cover Assembly is engineered specifically for the AR-10 and LR-308 platform, tailored for the 8.6 BLACKOUT calibre. Constructed from T6 6061 Aluminum, this component provides a robust yet lightweight solution for protecting the receiver’s ejection port. The assembly includes the dust cover, rod, and spring, ensuring a complete replacement or upgrade for your upper receiver. The unit weighs a mere 0.5 oz, contributing to an ultra-lightweight build without sacrificing structural integrity. It features an Anodized Black Finish that offers durability and a consistent aesthetic with other blacked-out components on your rifle. A key feature of this Gen 3 design is the Adjustable Set Screw, which allows for precise alignment of the Dust Cover opening and closing action on the receiver. This adjustability is critical for ensuring smooth operation and preventing binding, particularly important in custom builds. The dust cover is laser engraved with “8.6 BLACKOUT” on the front and “8.6 BLACKOUT” on the back, providing clear identification of the calibre compatibility. Please note that this assembly is recommended for use with Billet Uppers only, as the fitment and tolerances are designed to match the specific dimensions of billet receivers. This part is essential for maintaining the cleanliness and functionality of the ejection system in 8.6 BLACKOUT builds.
