East German AK night sight

[Jack the Ripper]

I dont consider myself a newb but this problem makes me feel one.

A set of East German nights sighs for my AK I can't seem to get on right :S

 

Clicking on the front sight was no problem but the rear sight... I just can't seem to figure out how it would connect.

I have done some google research and could not find that much. What I did find was that I probably received a RPK night sight instead of AK. (But I don't see a big problem here, shoud I?).

 

Can anyone explain how I can attach this nightsight on my AK?

 

Two pictures as attachment.

 

 

EDIT:

 

Never mind, RPK night sight wil not fit on AK rear sight.
