Their higher quality rail is lower profile, which helps in the cheek weld department.
Couldn't you just get lower rings and keep the same cheek weld? i dont' see how a higher base / lower ring combo would be different than low base / high rings to clear the scopes bell...
FYI I have the EGW 20moa base on it's way arrives tomorrow for my Savage 10 so I can mount my new Vortex 6-24x50 AO scope and still reach 1000K. This one has about 65moa of elevation adjustment. I'm curious if I'll have enough MOA after zeroing to get out to 1000yrds with 175gr SMK's?
