does anyone have one? Im preaty set on the mark4 6.5-20x50 but how does it compair to other high end optics?. Are they Bright? I havnt had the chance to look through the leupold yet it seem like ill have to order it in. The scope will be going ona tikka tactical, also are teh mark 4 rings any good, or for the sma eprice should i just get some badger ordinance rings?
