How well do the LT-719 LaRue Tactical rings work compared with conventional rings? I like the idea of quick detach rings because I am thinking about putting a picatinny rail on a tripod and then attaching my scope so that I can range targets while I am hiking and then use my GPS to check and see how much I was of by. Can you detach the scope and reattach it without losing zero too much, or do you really need a one piece base to do that?
