Im putting two disconnects side by side connected with a 2" nipple next to a two gang meter base. When I run the GEC to the first disconnect, can I then run the GEC through the nipple into the other disconnect? The nipple will have the service conductors in there as well. Or, can the nipple act as the ground?

You cannot run the grounding electrode conductors with the service conductors.

You are right, I was wrong.
I thought the exceptions were limited to EGCs not GECs but ...

A metallic nipple can be used as a ground but I always run a ground wire just in case something breaks or becomes loose.
A warning-- Around here we often use solid copper and I got call on 310.106(C). I can see if this was a long run with bends but a short nipple...gee wiz.
