White Label Armory Ejection Port Cover AR-10/AR-15 Black Oxide 10 Pack

The White Label Armory Ejection Port Cover is a direct-replacement dust cover for the AR-10 and AR-15 upper receiver. Sold as a 10 pack, it is an ideal option for builders stocking parts bins, gunsmiths running multiple builds, or shops servicing AR-pattern rifles. Each cover carries a black oxide finish for a low-glare appearance that blends with factory black phosphate and anodized components.

The ejection port cover is the spring-loaded door that closes over the ejection port when the bolt is forward, keeping debris out of the action. It installs as a standard, drop-in fit on mil-spec AR-15 and AR-10 upper receivers and is intended for use with the rifle's existing factory cover spring and detent.

Whether you are assembling a complete upper, replacing a lost or damaged cover, or simply keeping spares on hand for the bench, the White Label Armory Ejection Port Cover delivers reliable, repeatable fit across the AR-10/AR-15 platform.
