Pretty much this. I can get into the technical details about alot of things in the AR-15 but lube is not one of them. The consensus is as long as its wet it will work. If you dont want it to dry up or oxidize then deal with the increased toxicity of preservatives(it is really that hard to wash your hands after handing your gun?) The only thing grease should lubricate are the 4 rails on the bolt carrier.
