You do know that they did make some in an A-bolt II medallion grade some years ago.
Found one for sale from Boise gun, topped with a lupy vari x III for 1100.00 (although it might be gone by now)
I contacted my friend at Browning and the 2 models that were available in 300RUM were Shotshow specials only, had to be ordered there to be built, they built 2 configurations, an A-bolt II long range hunter with a gray laminate stock and a A-bolt II long range hunter with a composite stock in mossy oak brush.
Your dealer would of had to place an order through the Shotshow, did they do that?? If not then your SOL unless you search for someone who has one on the shelf, no current production runs for that rifle and no plans for a production run..
