how to remove rear sight ladder from a cz858/vz58
for the purpose of installing a scout mount .
if you bought a scout mount from marstar or wolverine , the box is marked for VZ but the instruction sheet inside are for a SKS, altho the actual installation of the mount on a CZ858 and the SKS are the same , the removal of the rear sight ladder are slightly different and it has cause some difficulties . hopefully some day (maybe it have already) the instruction sheet will be corrected.
1. do your safety check.
2. secure your rifle on a vise , if no vise then have another person hold the rifle firmly but do not have their hands near the rear sight.
3. i prefer to use a sharp tool with a handle but you may use the "L" shape front sight adjusting tool that comes in the cleaning kit.
4. place the tool in the gap which is in front of the ladder , press in hard to depress the leaf spring below the ladder and with the other hand push down on the ladder and slide it toward the rear.
there is another technique to removing the ladder, when the tool is in the gap , use the sharp tool as a lever and push down and lever it towards the rear , the ladder should pop out , if using this technique then i would suggest you keep your other hand away from the rear sight cos the tool tend to slip.
5. do not remove the leaf spring , it should be in place when installing the scout mount.
6. heres a pic just to illustrate what it looks like without the spring in place , note how the ladder are held in place.
7. pic of the scout mount on the rifle.
8. should you want to remove the scout mount and reinstall the ladder then the procedure are reverse .
helpful hints. you may want to scrape the paint off where the screws are in contact with the rear sight block, as for you would want a metal to metal contact and not have paint in between, also its a good idea to secure the screws with loctite , once you are zeroed in.
