Mil-Spec AR-15 Ejection Port Cover.

For upper parts kits I will always use STAG ARMS. They are never bent and are finished well. I've used other brands for dust covers and it's a crapshoot if they aren't bent when I get them. They'll work but they won't have perfect fitment. After trying other milspec dust covers I've come to realize trying out other brands is a waste of time.
Thank you for the consistency Stag, much appreciated.
