No direct experience, but most Mauser sftermarket stocks need to have a bolt channel cut into them if you have a turned down bolt (which seems likely, since you are also asking about a scope mount) ... this would seem to be problematic with any kind of overmolded furniture as the overmolding doesn't seem like it would like being filed on ... My experience is also that the stocks, unless the barrel channel is already set up for YOUR contour barrel, need to have the barrel channel opened up ... this would also be problematic for the overmolded stocks ... more questions than answers, but maybe it will help you in the long run.
