Strike Industries AR-OMUDC Ultimate Dust Cover .223/5.56 Flat Dark Earth Polymer for AR-15

Upgrade the ejection port on your rifle with the Strike Industries Ultimate Dust Cover (AR-OMUDC). This direct-replacement dust cover is molded from a durable, high-density polymer and finished in Flat Dark Earth to match FDE builds. It is built for standard AR-15 flat-top uppers chambered in .223 Remington / 5.56x45mm NATO and drops in on common M4 and M16-pattern rifles without modification.

The upgraded UDC design uses a double injection mold with an overmolded rubberized soft sealing lip that seats against the upper receiver for a tighter barrier against debris, dust, and fouling than a standard stamped cover. Tool-less installation and easy disassembly make field swaps and cleaning simple, and the cover is shaped to clear most aftermarket charging handle styles.

Whether you are replacing a worn factory dust cover or finishing an FDE-themed build, the Strike Industries Ultimate Dust Cover brings a tough polymer construction and a sealing-lip design to one of the most exposed openings on your AR.
