Ok, so I have a fully built and blueprinted 700 sa that I'm in live with. It's an M40 replica. Trouble is, my bolt has a badger knob. Not so spec for this build. What would be involved in putting a bolt from a different rifle in it? I imagine having the lugs trued. Any other problems with this? Or, just having the handles swapped. I understand they're only brazed on from the factory. Is that a possibility? Inform me please...
