Look at Remington and Savage who are now out sourcing the production of their guns. Sad state that they are taking skilled people here out of work.
I do agree that looking into the possibilites are great. However some people here work in the metalworking industry and we know what can be done reasonably and what can't. I wish I would have done my apprenticeship in die-making rather than becoming a screw machinist. I did not like the idea of the stress involved with making and working on dies. Many guys in the apprenticeship program looked like they were well on their way to a breakdown.
Re-welding them is much easier to do. Much cheaper to do also.
