I am going to be getting a 452 Lux or Ultra Lux soon and was wondering about the wood options on the Ultra Lux. I know the CZ-USA site says the ultra is in beech only but I keep seeing specs from various retailers listing it in walnut too. I would like to know if they are mistaken or not. Also if anyone has an opinion on the difference between the barrel lengths of the lux and the ultra lux. I am a competition shooter and shoot a 27" anschut so naturally the longer barrel appeals to me.
