I've been looking high and low for a simple tough set up for aperture sights on my 595 Whitetail Hunter. I'm having a hard time getting specifics about the factory receiver dovetail - Is it same as Sako ?- I see Sako peeps in online auctions. Is it same or close enough to CZ 527 ? - because NECG has some options for CZ. What are the standard dimensions of it ?.. I can;t find a spec or drawing online. If I can't mount directly , I guess I 'll have to mount a picatinny rail and then use a peep on it. Just wanted to keep it simpler. Thanks in advance.. and by the way.. I've had this Tikka for a while and stopped using it but am now motivated to use it more since I just returned from a trip to Norway and spent consdierable time in the shops talking about rifles and hunting with the locals. So I'd figured I'd join the Sako Forum..
