The " commercial Mauser " is most frequently seen mfg by Zavasta ( more commonly known by Mark X ) , and occasionally see some mfg by Santa Barbera ( Spain) .
Bfy43 name checked the Rem M798 , but a whole buncha well known rifles used Mark X actions , if not barrelled actions . Likewise , Interarms sold a metric boat load of actions / barrelled actions to small builders/ gunsmiths / hobbyists .
But people into such thing will be tickled beyond belief to have a source for Magnum Mauser actions .
I picked up a beautiful Zastava Interarms Mark X .308 with a Leupold scope years ago from a walk-around seller at Timonium, but sold it later because I was focused on getting an EBR in .308.
Agggghhh... should have kept that beauty by eating pork & beans for two weeks.
