I'm mostly just curious, although given the price of a large ring mauser, its a little more then curiousity.... First, the most common surplus seems to be the 48 mauser. Is this a direct clone of the '98? Second, How hard is headspacing a barrel onto one of these rifles? Third, what else needs to be done to convert one to .308, or potentially .30-06? I take it the rounds will feed and extract...does the internal magazine need to be modified? Any recommendations on inexpensive stocks? What about the ATI stock?
