AT3 AR-15 Dust Cover Assembly

Also called an AR-15 ejection port cover, the dust cover on your AR-15 helps seal your AR-15’s bolt carrier against the elements while not in use. This is a perfect replacement part if you’ve got one that’s damaged, or just want to add some color with one of 8 Cerakote options for a custom look. This kit works on any mil-spec upper, and includes the ejection port cover, steel rod with c-clip, and the spring.

Be sure to check out the AT3 Upper Parts Kit to get a matching forward assist with your dust cover! If you’re looking to replace an existing dust cover, check out this guide for instructions.
