"Sporterizing" non-collectible milsurps usually isn't about accuracy (though, it can be with $$), and certainly isn't about being able to do it "cheaper" than today's amazingly accurate factory rifles in the $350 range.
It's about having a rifle that's not like everyone else's on the firing line, that shows a bit of "individualism on a budget"- and tweaking every bit of accuracy out of them that you can. Sometimes, the results can be impressive.
