I have the 4.5-14x50, 30 mm LR/T MK4. Its on my 300 RUM. I love the glass. To me, I can almost see the world brighter through that scope then my own eyes. I have used it to shoot out to 1150 yards with no special bases or rings/inserts. So it does have some elevation. I just now wish I woulda got the 6.5-20 because I want to shoot out to about 1500 yards eventually and I dont wanna have to buy a new scope. The clicks are very precise. You can click up to 1000, go down to 100 or 200 zero, then go back up, etc... you will be dead on for whatever its set to, put it that way.
