Yes. I have also noticed some new wear on the upper, just in front of the trigger bar and the plunger you spoke of. It is from the lever (whatever you call it) that is activated by the trigger and in turn depresses the trigger bar that allows it to fire. It seems that when the upper moves backward, the lever is in contact with it.
