Boyds sells a stock for the cz, but it is designed for any model that uses the barrel lug. Whether or not this model could be used for the American I'm not sure. On the bright side the one they sell is fairly cheap (65.00 US)and a very nice stock (albeit unfinished). I got one for my Varmint and had to sand the barrel channel as it is designed for the standard or Lux model. Check out their website or call Laura and find out if it could be used for an American. Good Luck
