I would honestly get a standard BCC from DD. I have a factory Mk18 with 4000 rounds through it with only a few minor hiccups in the extreme cold we had this winter. I think the only benefit you'll get from a chromed BCG is ease of cleaning as I have had no problems using a standard BCG in all of my AR15s.
i just saw one on brownells for a good price and i was told its always good to have a spare rifle when going to comps.
