I have a rem 700 in 7 rem mag. The scope is a burris fullfield II 6.5-20 1" 50MM that Im having the Tac-2 turrets installed on. For bases Im thinking of going with either a 20 nightforce or leupold picatinny rail (any recommendation for either?) Should I have this rail installed by a smith and have it pinned and the whole 9? For rings Im thinking of either the burris signature Zee rings or the burris XTR rings. If I go the XTR Im assuming Ill have to have them lapped. Any advise would be appreciated thank you.
