will try to get some pics tomorrow-need to learn how to do that here anyway. i got a CZ 550. it is not marked "american" or anything else. 308. i assume 1/12" twist. barrel is 24 3/4". quite heavy config. about 7/8 dia. @ muzzle. the stock is a sporter. no way it could be called a varmit or tactical stock. it is wood. i see nothing on the current cz site except a hunter long range which is only in 300WM. likely a D/Ced model? any ideas? thanks.
