My first precision rifle is finally complete and my scope has arrived, so the very last thing to do is to find a base and mount it up. I have been shooting this rifle of a few months with a loaner scope from a friend. This friend uses ADM mounts and hasn't ever had issues with them. However... the general consensus here is that ADM mounts are not awesome and can/will cause issues with tracking and return to zero. I intend to use this rifle for long range (out to a mile max) and possibly some PRS matches. I would like a QD mount, as I may on rare occasion swap this scope to another rifle for temporary use. I need something with 30mm rings and would like 20moa of elevation in the base. So.... what are the appropriate scope mount choices for a precision rifle?
