With the EGW bases your will want the lowest rings you can get. Atleast this holds true on my remington and savage. On my remington I use the egw 20 moa base with the burris signature 30mm medium rings (.190") high with a 6-24x50mm SIII scope and I still have atleast .200" of clearance with a heavy barrel. I originally tried the Burris xtr medium height rings and they sat ungodly high.
