CZ 452 vs 455 in 22lr

I've mounted mine with a Vortex Diamondback HP 2-8X32 in high Warne 7.3. Was able to only take of the sight blade.

Removing the pinned portion of the rear sight is straight forwards. Don't attempt to remove the pin! Just hold the rifle in one hand and press with the thumb of that hand over the 200m mark. While pushing down hard, use your other hand to pull back on the sight leaf.

Basically there is a vertical slot that houses the pin that you can see from the outside. The slot is open at the bottom which allows the pin out of the slot. The leaf spring retains the pin in its slot while forcing it up.

Just noticed that MB beat me to it....
 
I haven't really played around with the 452, but the first rifle I bought was a 455. Got the trigger kit from YoDave. Action is smooth, fit and finish is excellent. I'm on 4000 round or so, and accuracy is still superb.
