Low Optilock ring mounts/Mk4 50mm didn't work out on my Tikka 595 (Different rifle I know). Probably a couple mm too low. I wanted to mount the scope as low as I could to get proper eye alignment, I had a rail and low rings, but it was a bit high for my liking. Ended up with a different scope with a 44mm objectilve mounted on that rifle...
