The scope has 55 MOA of elevation and 41.3 MOA of windage adjustment. The windage knob is like many target scopes in that the knob is marked from '0' to 9L then 10 then 1R to 9R and back to '0'. You can zero the knob by loosening two set screws and slipping the knob. The elevation knob can be zeroed the same way. The elevation knob however is a bit different from the norm! It has three rows of numbers, one above the other. The first row goes from '0' to 20 moa. The second row goes from 20 to 40 moa and the third row from 40 to 60. This sounds strange but when you see it, it will become much clearer. The numbers '0', '20' and '40' line up one above the other. To tell which line of numbers you should be looking at as you crank up or down elevation, there is a small red pin on the knob top. If it is flush you should look at the bottom (0-20 line. If it is sticking up about 1 mm you should look at the middle row. If it is sticking up about 2 mm then you use the top/third line of numbers. The pin is quite noticeable in movement as you jack up the elevation. One of the things that really caught my eye was the parallax adjustment-it is below the elevation knob. This is a very handy place for a competitive shooter like me. I am left handed and shoot from that shoulder. But I use left bolt/right port actions. To adjust the parallax on a front adjustment I would have to get out of position and adjust the objective lens. On a scope with a left knob for parallax, I would have to use my left hand to adjust, which is a stretch. With the Kahles K10-50x56, all I have to do is reach up with my right hand and turn the wheel below the elevation knob while looking through the scope. I love this feature. I turned both the elevation and windage knobs a half dozen or more times from one limit to the other while checking out this scope with no ill effects and then shot a number of pretty small groups while putting in large adjustments. After all my abuse I feel this is a welcome addition to the small group of top quality high power variable target scopes on market. I would be happy to use one. MSRP: $3,110. May all your shots be in the center and very close together! Parralax adjustment is done with the wheel below the elevation knob.
