I would be disappointed if they didn't come with a dust cover, more so if there was no provision to attach one. I really see no reason not to include one.
I bet $5 right now that they don't ship with a dust cover. None of the photos of the NEA102/25 ejection port side show a dust cover, and most of the photos show the other side only.
I don't think that lack of a dust cover is a deal breaker (for me) - I don't see one on that paragon of NR rifles the ACR - but it is weird to have provision for one and not install it. Maybe they couldn't get the port and the cover to line up ;-) I'm just glad they ditched the FA.
