I make pics to compare this hungarian M 43with his father and grandfather. here on nitroexpress is also a post about a mauser with a mannlicher magazin.
well this M 43 is a mannlicher with a mauser magazin. interesting that the last repeating rifle the deutsche wehrmacht accept was a M 88 action again. I know that this rifle is terrible rare and military collector's would not like it if you butcher it to make a sporter but would be indeed a good possibility.
