Yankee Hill Machine Co Dust Cover, 9MM, Black
This caliber-marked ejection port dust cover is stamped “9MM” so you can identify a chambering at a glance, a handy detail if you run more than one upper. It’s a complete drop-in assembly — cover, rod, retaining clip, and spring — that installs on any standard AR-pattern upper the same way as the factory cover.
