Recently bought Slavia 620 in good condition and I try to refresh it, but have problem with rear sight. I can't move it for windage, it is stuck moved fully to the right side, so rifle shoots about 1" to the right.
Someone have idea hove to move it? It sits on kind of dovetail as shown in the picture.
Advice needed, please!

Get a hammer and a piece of scrap wood or leather and gently tap the rear sight's dovetail back towards the center. Let it soak in penetrating oil before going at it.

The best penetrating oil is a 50/50 mixture of Acetone and ATF (automatic transmission fluid).... almost is good is 50/50 Lacquer Thinner and ATF....

European dove tail sights are applied from the right ride and tighten as they approach the left, slight taper. There will also be a small center punch mark holding the sight fixed in place. As said a couple drops of penetrating oil to start. Then with a wood dowel or brass punch tap the sight back into alighnment. Once done and shooting straight re center punch the hold mark for the sight.

Thank you for the advice!

I tried to spray with WD40 and hit with hammer and punch tool really hard in both directions - no move.
Then I soaked in kerosene overnight and tried again - no move at all.
Will try 50/50 mixture of Acetone and ATF next - how long to soak?
If I understand good, the sight should be removed by tapping from left side to the right only?
May it be removed completely to be cleaned?

Thanks to everybody for help!
Today I bought acetone and ATF, mix 50:50 and soak sight for 1 hour.
Then tap it from left to right side with hammer and metal punch.
At first were was no difference, but after 6-7 really hard hits it started to move!
So it worked for me, I took the rear sight out! :D
Now will clean it, repair the damaged spots and blue them and re-install.
Thanks to everybody for help!
