I've owned several of the Sako AV's over the years, and still own two. And a couple of AIII's too. I like them a lot! They are very well made, reliable, accurate, with very few quirks or problems. The guide rib issue has been mentioned already. If that's a concern ( I've never had any problem with guide ribs ) a spring kit is easily ordered and installed. Stoeger has them. I did that "upgrade" in a .375 that I had. For my peace of mind, not because there was any problem.
I like the scope mount system. No bases to come loose, and extension rings are easily found if one needs them.
Sako triggers are excellent. Never found a need to replace one. Adjustable and crisp.
I've never, ever had a Sako that was poorly machined or mis-aligned in any way.
I tend to have all my bolt action rifles pillar bedded, but it's not strictly necessary with Sakos, just something I do.
Compared to Remington M700, Winchester M70, Ruger M77, and most of the other common USA brands, the Sako A series rifles are clearly superior in my experience.
