Seems a lot of confusion, here is what I know. In 1999 I saw the prototypes of these rifles at Lawrence Ordinance Arms, and was lead to believe they were made in Australia, in Lithgow (any 303 collector knows that place). During the same visit I visited the museum at the Lithgow factory, a great one. It has taken them a long time to come to market with the .308 one, it was discussed at the time, which is the one I have always wanted. FYI still sells in AUZ, for AU $ 1050.00 (CAD $ 874.00) excluding the extras Marstar is throwing in. I do agree it takes Marstar forever these days to process and order, oh well patience is a virtue.
Perhaps a real .303 is cheaper, $400.00+ for a good like new one, but as a collector rather beat a new non original, noting some mention of .303 been rebored (aaaah messing up an original) to .308. well Enfield did not even get that right, the only really successful one was the Ishapore 2A, the DCRA target version, the rifle was not considered strong enough for .308, the Indians used different metal, and that is way I assume the AIA M10 is heaver for the higher .308 pressures. .02c
