Need Help!! with rings and bases

[win270wsm]

I have just ordered a remington 700 sendero sfii in 300 rum along with a vortex viper pst 6-24x50 ffp. I was woundering what rings and bases I should order for this combo. Gun will be used for hunting whitetail and elk to 600 yards to start. May expand range at a later date. Thanks your help.
