The Wilson Combat AR-15 Ejection Port Dust Cover Kit (Wilson Combat part no. TR-EPD-K) is a direct-fit replacement for the spring-loaded flap that shields your AR-15 or AR-10 upper receiver’s ejection port from dirt, sand, and moisture between range trips. Wilson Combat builds this kit to the same tight tolerances the company is known for on its match-grade rifles and pistols. It swaps in using the standard AR-platform hinge pin and retaining spring layout, so installation stays simple for a home armorer. Whether you run a duty carbine, a precision rifle, or a range gun that sees a lot of dust, keeping the ejection port covered when the bolt is closed helps keep grit out of the action.
