I've handle a few briefly and thought they were cool enough, but never got too serious about them because I was only really interested in rifles from combative parties in WWI and WWII. I've always heard people rant and rave that K31's were the 'swiss watch' of the milsurp world, how they would easily cost $1000-2000 or more to make to the same level of quality today, yadda yadda.
