Question:
Can I use a bare #4 in a feeder pipe from meter panel combo to main panel as ground?

A
Answer:
It seems that you are asking about an equipment grounding conductor and they are allowed to be bare, covered or insulated as stated in 250.119. You don't indicate what type of raceway is being used (feeder pipe) but for example 344.14 for rigid metal conduit has wording about avoiding contact with dissimilar metals. Check with the AHJ to see if they have a problem with the bare conductor in your situation.
