BTW, if you want the best, look for a Mauser or Steyr WW2 armorers replacement barrel... it will probably index perfectly and headspace correctly as well... next would be any "GERMANY" barrel, followed by any "MADE IN GERMANY" barrel, after that, it is a crap shoot!.... I do have some nice take off barrels, but they are not new?...best to you, til...lat'r....GT.....
