Find some folks who shoot military bolt matches or CMP matches and visit with them. Very often one will come up for sale that is clean and serviceable. Not too long ago I was offered a sportered 03A3 (attending a different shooting event) at a reasonable price, so I took it. I retrofitted it back original (had left over parts and wood from another project), and other than the holes that were D&Td for the scope, it is back in 'as issued' dress. I sold it to a fellow club member who wanted to shoot the mil bolt matches with us, and he is having a great time.
