My 452 Ultra Lux was part of my first rifle purchase (also got a 452 Silhouette and a T/C R-55 Benchmark at the same time). My new 452FS actually beats it in accuracy, and the scoped Silhouette is in a whole different league, but in my opinion, the Ultra Lux is probably the most comfortable and fun out of the 452's to shoot.
Mine also has a more interesting stock than my quite ugly 452FS (I'd send the FS back if it wasn't the most accurate .22 I've shot to date - it's really that good).
Just be careful with it, as the long barrel tends to want to smack into things. Enjoy it and be safe.
My full stock CZ is my most accurate 22 as well and have one of each of then. I'd go so far to say that at 25 yards it may be more accurate than a couple of my 17HMR's. My Cooper MachII is a one holer at 25 meters, G
