Product description

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.

Fits as expected in Cerro Forge AT3 cerakote upper. AT3 install videos are VERY helpful, thank you!

Colors matched all of the other parts I purchased from AT3. I only leave 3 stars because the e-clip was missing from the retaining rod. Details matter.
daniel.schmidt Verified buyer
I'm unfortunately disapointed. The color is great BUT the detente nub on this part sticks out WAY too far, making the cover impossible to close on the build I'm working on, no matter how hard I force it. I've generally noticed that AT3 uses springs on detentes that are aggressively too long, I've also had to trim their springs for takedown pins.
