Just realized, after buying a 224 Valk upper, that some AR dust covers open up and others down. Today’s new toy opened down, which freaked me out until I looked at others and found some opening down or up, even within the same caliber, without obvious reason.
So, why? Just due to manufacturers whim? Is there a real advantage to one or the other?
