I have two Mausers, a '96 Swede and a '48 Yugoslavian. The Swede I bought for $100 with essentially no bluing on the barrel. The stock disk said the barrel was still in good shape internally, though. I had it rebarreled with a medium-weight Shilen 1:8 twist 24" tube, had it polished and reblued, had two-piece scope mounts installed, and had the bolt handle bent down. The gunsmith work was (IIRC) about $350. I then installed a Timney trigger and bedded the action into a Fajen thumbhole sporter stock.
I think it's beautiful.
I still haven't found a load it will shoot worth a damn.
As far as I can tell the gunsmith (no longer in business) throated the chamber [i]way[/i] too deep. If I seat 155 grain bullets out to just touch the lands, they are WAY WAY out past magazine length. And I had the rifle built with the intent to shoot 140 grain bullets. I'm not pleased. It looks like I need to have the barrel removed, shortened, rethreaded and the chamber recut for a shorter throat. That won't be cheap.
My other Mauser is a simple sporterization. I have a Timney trigger, a Richard's Microfit semi-finished stock, and an AO Smith Scout scope mount. The only thing I needed a gunsmith for was removing the rear sight and cutting the barrel off beind the front sight band and recrowning. I'm still working on inletting the stock.
I'd eventually like to get all the tools so I could do barrel changes, bolt lapping, and so forth, but I don't have the time and I don't have the workspace either. Not to mention the money.
As always, YMMV.
