I notice that the newest DD4 rifles seem to be once again using the metal mil-spec ejection port covers, even though DD previously went to the polymer covers on their rifles back in ~2016. Does this mean that they're returning to the USGI covers again? What gives?

We made a decision to use traditional metal dust covers instead of polymer on all DD4 (full ambi) guns.

Understand, but what was the logic behind that decision? Also, does it signify a return to the USGI dust cover on newer DD rifles moving forward?
