CZ's are great rifles; I have a couple 452's but don't consider them to be "youth" size guns. If a CZ452 or 455 fits the kid, it is a great choice. I gave my nephew's 12 year old son my 452 with a 16 inch threaded barrel. The rifle fit him well and he loves it. I gave his younger brother a Ruger American and heard no complaints. I am not familiar with the CZ Scout but I prefer not to buy a rifle that will be outgrown in a couple years.
