I've got the 452 version of that rifle, a 453, and another 452 Scout. I love the CZ rifles. They are about the best you will find under $2000.

I put a Williams peep on my 452 like yours. The extra long sight radius makes shooting irons very easy and it's easier for my older eyes to use the peep. I do love the ability to adjust yardage on the fly with the tangent sights though. I could hit an aluminum can with mine at 50 to 100 yards just by sliding the sight to the correct yardage mark.

Keep on the lookout for a 453.If you find one snatch it up. It will be the most accurate 22 you have ever shot unless you own a 54 action Anschultz.
