Gents, I really don't know a lot about the different variants of the Mauser design. I know what the large ring and small ring means. That's about it. I've heard about the intermediate action length once or twice. Here is the question: - is a Mauser rifle chambered in 30-06 (commercial model from the 60's or 70's) difficult to re-stock? - is there some kind of standard set between all those, different makers or is it all over the place when it comes to the action sizes, spacing between the action screws or interchangeability of the parts? I would really appreciate any feedback. Looking at a commercial 30-06 or 308 made by Parker Hale or Husqvarna back in the days...and this is the only, unanswered part about possible purchase. Thanks!
