Timber Creek Outdoors Billet Dust Cover AR-10 Flat Dark Earth Aluminum

The Timber Creek Outdoors AR-10 Billet Dust Cover is a precision-engineered replacement for the factory ejection port cover on Mil-Spec AR-10 upper receivers. CNC-machined from aircraft-grade aluminum and finished in a durable Flat Dark Earth Cerakote, this drop-in door delivers the brand's signature Billet styling with 3 angled lightening cuts and a smooth, hard-use coating that stands up to field carry without sacrificing function.

Designed to fit any Mil-Spec upper ejection port, the cover installs in place of the standard stamped door and gives any AR-10 build a refined, custom look. Whether you are assembling a new rifle or refreshing an existing platform, Timber Creek's precision-machined aluminum body keeps action smooth over the ejection port and adds distinctive character to a wide range of AR-platform builds.
