The Tapco TAP22097 Ejection Port Door Cover Kit AR-15 Black Aluminum is a direct-replacement dust cover assembly for standard .223/5.56 AR-15 upper receivers. Machined from lightweight 6061 aluminum with a black finish, it includes the door, knurled rod, spring, and hardware, offering a durable, low-friction upgrade over factory components while eliminating the traditional C-clip for simpler installation.

This cover kit is well suited for keeping your rifle’s ejection port protected during range sessions, training days, or general use, helping to reduce the amount of debris entering the action. Its straightforward design makes it a practical choice for new builds or refreshing a well-used AR-15. The thoughtful engineering behind the knurled rod and secure fit reflects Tapco’s focus on functional, reliable accessories for the modern rifle owner.
