The Strike Industries Overmolded Ultimate Dust Cover (brand part no. AROMUDC223BK) is a black polymer .223/5.56 AR-15 ejection port cover and the next iteration of Strike Industries’ original Ultimate Dust Cover. It upgrades the design with a double injection mold process that overmolds a rubberized, soft sealing lip around the cover, closing the small gaps that let debris and water sneak into the ejection port on a standard cover. The cover still functions exactly like a factory dust cover, snapping shut when the rifle is idle and popping open automatically on the first shot. Shooters running their AR in wet, dusty, or sandy conditions get real weather sealing instead of a purely cosmetic upgrade.
