i am looking for a 20 moa scope base. Live in phoenix and need it quick. Any ideas where to get one locally? i have a savag 110 that is setting up very low when a scope is mounted. I am thinking that a 20 moa base will help. it is also setting up way out to the right. I am using burris extreme 2 piece bases and rings. Should I shim them? Help, I need a fix quick, supposed to shoot this weekend. If you have any good Phoenix gun shops let me know, Thanks!
