Outside what the CMP sells, I haven't seen an M1 for sale under $700 in the last ten years. I'd say you can expect to pay minimum $700 for a shooter grade with a halfway worn out barrel, beat up stock, mix-master parts and $1000-1500 plus for a one that has all the correct parts, cartouched stock, good barrel, etc. You might get lucky and beat that, too. Nothing wrong with mix master for a shooter. That's how they were done when the rifles were in service. The depots made little effort to match part origin in the rifles during rebuild unless it was for a special purpose.
