Look at the CMP site. THey won't be selling anyone most of the rifles on your list. Unless some of the foreign loans come back into the country through them, which is unlikely IMO. Unless CMP is given some of the more modern firearms I think they are soon to be closed.
They still put up most of the rifles on that list up in online auctions from time-to-time. Also, some are available in the stores. Orest at the CMP has said that there are a few years worth (maybe 2-3?) of Garands left for sale via mail order, and then the CMP will transition back more to their original core purpose of promoting marksmanship training.
