Forgot to mention the AK side rail mounts. There are several models but the ones I have had experience with are shown below.
The side mount locks onto the rifle's siderail in the same manner as the KOBRA. It is rock steady, sits directly above the bore, and will accept any sight having either Weaver or Picatinny rails.
The difference between two models shown is that one sits higher than the other which allows the iron sights on the rifle to be used. The rail on the taller model is also somewhat longer than the rail on the lower model.
