Timber Creek Outdoors Billet Dust Cover Features The Timber Creek Outdoors Billet Dust Cover replaces the factory stamped ejection port cover on Mil-Spec AR-10 upper receivers with a solid machined billet aluminum piece. That billet construction gives the cover a more substantial feel and tighter fit against the receiver than the stamped steel parts typically found on AR-pattern rifles. Covering the ejection port keeps dirt moisture and debris out of the action when the rifle is not actively cycling which helps protect the bolt carrier group and internal components. Being purpose-built for AR-10 pattern upper receivers it installs using the same hardware and spring tension as the factory part it replaces. Finished in Flat Dark Earth the dust cover matches a wide range of earth-tone AR-10 builds from hunting rifles to tactical configurations. The aluminum material resists the dents and bending that stamped steel covers are prone to after repeated use or rough handling. Upgrading small components like the dust cover is a simple way for builders to add a cohesive finished appearance to a rifle without touching major function parts. For AR-10 owners who want a more durable better-fitted ejection port cover the Timber Creek Outdoors Billet Dust Cover is available for sale at GrabAGun.
