CENTERINg WINDAgE AND ELEVATIoN
ADjUSTMENTS To ACHIEVE oPTIMUM
ADjUSTMENT TRAVEL
Making windage and elevation adjustments moves the entire erector
system horizontally and vertically inside the scope . If the erector
system is off to one side – as a result of having been mounted on a
24
non-adjustable mount – the adjustments won't provide equal travel
in all directions . To regain full balanced travel, you must recenter the
adjustment as follows:
1 . Turn the windage adjustment to the point that it stops moving .
2 . Counting the clicks or hash marks, turn it all the way in the
other direction .
3 . Turn the dial back half the amount of clicks or hash marks
counted .
4 . Repeat this process for the elevation adjustment .
