Springfield 1903 Receiver with Remington Barrel

[usabaker]

What I'm wondering is if I can return the rifle to its M1903 config.

Unless your returning the rifle to the original configuration for fun and are not worried about the cost I would say it's not really worth the cost. With what you will end up paying you could buy a really nice original 1903. I did two that I use as my shooters and was not cost effective but FUN and rewarding.
