Removing front sight from CZ 527 carbine ?

[bcraig]

I am curious as to how this is done?
I have taken the one visible screw that holds the ramp to the rifle barrel and then depressed the spring plunger and removed the bead but can figure out how to remove the sight !
Would appreciate the help here.
Thanks

I think they are also soldered on.

[Edit: Actually I may be wrong - I'm not sure what item 5 is (insert?) but it may be the culprit - refer manual in the link below.]
