Should I mount my Vortex Viper 6.5-20x44 on my new Savage 11 Long Range Hunter .308 with a rail type base? I have looked at the options on Optic Planet and it looks like I would need the 'round top' EGW type rail for short action Savage & then the 30mm rings. I have a choice in the rail of 0 or 20 MOA ( I was assuming the 20 MOA was the way to go?) Then will the Burris Picatinney x tac rings mount on the EGW rail? and if so, what height rings will get the Vortex x44 off the barrel? Thanks much!
