I did find a source of 91/30 milsurp barrels in VG condition for under $200. A bit more money and could get a new one w/o a mystery as to performance? Since it's resnipered, technically, it's already been altered from it's original "collector" status. I'm not out to build a Precision Rifle either . On the fence of how far to go with this. Definitely would need to get connected with a guy for installation either locally, or nationally. I don't mid shipping/waiting.

I did research that McGowan Precision Barrels makes nearly complete barrels requiring only the extractor notch to be cut.

This could be a route to go:
Mosin Nagant - McGowen Precision Barrels
