As much as I love my CZ's, I do have two small issues---their front sight hoods are a little strange and the rear sight on the .22's is large and clunky and often in the way of a good scope--if the rear sight leaf is pushed straight down hard, it'll slide rearward right out of the base, it'll pop right back in if you ever decide to sell the gun. I remove the front sight hood, grind of most of that angle that originally faces the rear, saving just an eigth of an inch or so across the top, touch up the edge with a little perma blue, then reinstall backwards--looks much better---
