The factory rings work fine up to 42mm objective.
I replaced the aluminum screws in the rings with blued steel ones from the hardware store, on my T3 Lite .30-06.
If I were not going to use the factory rings on my Tikka T3 ( to keep it light weight ), I would mount a single rail, and use Warne rings on the scope, and swapping with a red dot sight doing the duty of iron sights.
