What is your opinion for a chrome vs moly lined barrel for a AR .556 shooter that may shoot a couple of 100 rounds per month. A lined barrel is $40 cheaper but I don't have experience to make the call.

There's gotta be a dozen threads on this. The major issue isn't how many rounds you shoot, it's how fast you shoot. High rates of fire (mag dumps or rapid fire) speed up erosion of the barrel throat of unplated barrels. The $40 bucks up front for chrome is much cheaper than a new barrel down the road. If you like rapid fire, it can be a short drive.

The US Army match team uses plated barrels for all rapid fire matches (possibly for everything), they've found no significant difference in accuracy but significant differences in service life.
 
If you're going to be out in the elements for long periods of time like the military then chrome lined barrels make sense. If your just the average person that just hunts or shoots they are unnecessary if you clean your gun regularly.
