I’m just starting to dip my toes into the long range/PRS/NRL hunter world. All of my hunting rifles have either talley or dmz one-piece base/ring setups. I’m planning to get a scope with a 34mm tube and will need some new rings. All of the setups I’ve seen online run a pic rail and rings. I understand that a rail & rings give you you a little more fore & aft mounting options, but is there any other reason for using separate components?
