I posted this on another category with no luck. Is there any way to mount a POSP style scope on a yugo U/F without drilling into the reciever? Has anyone done something similar to this? thanks for any help.

I asked this exact question of the guys at Tantal.  This is the short version of what they told me.  First you have to drill into the reciever to put on the side rail.  This, with some cutting and bending of the tangs of the folding stock will fit.  However, you have to get a specially made rail/scope combo as the scope has to be slid on the rail from the front - from the back it is blocked by the folding stock.  Once you get yourself to that point and get the scope on the gun, the folder won't fold as the width of the rail and the scope mount are too wide to fit and allow the folder to close.  

Yes, it is a bummer.  The only thing you can do is go with the Ultimak - which for my purposes locates the scope in a position I don't like or go with a dust cover mount - which most people excoriate as being prone to lose zero because of the impact of the bolt carrier group into the topcover when the gun is fired.  

For your purposes I think a sidefolder is the way to go.  

I just decided to leave the sights as is - although I am thinking about installing a rear peep sight.  I prefer that setup from shooting ARs.

Please contact Tantal about this. - as I am just repeating what they told me.

Thanks for the info. Following up, Can I mount a POSP type scope on a dust cover mount?

Just my $0.02, but if you are thinking about putting a red dot on it and shooting at relatively short ranges 100yds or less - which seems to be fairly realistic for a 7.62 AK, the dust cover mount wouldn't be too bad - but if you are going to use a scope and shoot out to longer ranges, I would wait until someone comes up with a good solid mounting solution rather than go with the dustcover mount.  YMMV.  

Cheers and good luck.
