I’m going to (order) install a one-piece scope base on my Remington 700 06. I need to move the scope a little further back (eye relief) than the two piece mounts will allow. So my quandary is… Do I get a flat mount or a +20 MOA? They're the same price. Will I ever shoot to 1000 yards? Who knows! But I don’t see any disadvantage in getting the +20 even if I never really need it. Or is there something I need to know that I don’t?
