I have a Sako Kodiak, and a half dozen older Sako rifles and one other M85. Older Sakos are basically flawless. Wonderful rifles. The M85 design is very very good, smooth, precise, and ergonomic. I have only one concern. The extractor and ejector are placed in such a position relative to each other that in many ( not all) M85 rifles the case will eject at a nearly vertical angle. That makes the empty case fall back into the action after it bounces off the right hand turret of the scope. In problem rifles, if you examine the clearance between the extractor claw and the bolt face, and the position of the ejector, you will observe that the case will start moving vertically before moving horizontally if it gets any momentum going from too much space between the claw and the case rim.
I hand this problem with both my M85 Kodiak .375 and my M85 Bavarian 7x64. One solution is to use very high mounts. I don't like that solution. So I tried a longer/stronger extractor spring supplied by Gre-Tan in the USA in the 7x64, the claw grabbed the case tighter and I had no more problems.
I wasn't so lucky with the .375. I had to have a machinist make a new claw extractor for my Kodiak. My new claw is made to tighter tolerances, and everything works perfectly now. It cost me only $50, made by a hobby gunsmith / machinist in Alberta Canada who volunteered for the challenge after I posted on a local gun website complaining of my woes. The solution is simple, elegant, and foolproof. I only wish Sako had taken the time to build this part of their rifles more carefully in the first place.
So my advice is, if you want to use your Kodiak with the excellent factory original sights, definitely go for it. If you are mounting a scope. please check the ejection angle of empty shells very carefully.
