Unless you have all the parts or a source for cheap parts, this probably isn't a project worth taking on. Barrels are actually not as hard to press as people realize, I had a friend do a barrel press project on my behalf and it was the 'aluminum jig' that that was the biggest cost/time.
You have to ask yourself why this receiver would have been stripped and I would think some major flaw/issue would be the answer. So I would think it would only have value as a display piece at best. But, as others have said, you could put it up on an auction site and see.
