Use a lens brush to remove loose particles of dust and a high-grade glass cleaner
applied on a cotton swab. Begin moving in a circular motion from center to the outer
edge of the lens. Do not apply excessive pressure.
Zero Stop Feature – Adjustment (IBA Version)
The Zero Stop feature on the Nightforce scope allows you to find your elevation zero
quickly and accurately in less than ideal situations, especially if the zero is lost. Once
set properly you will be able to turn the elevation turret downward until the internal
clutch stops the adjustments, at which point you will be back to your pre-set zero. You
will be able to set the stop at any zero/range you prefer.
Upon receiving your XM-3 rifle the zero stop may or may not be set. Assuming the
feature is not set follow the below instructions.
1. Zero at preferred range using ¼ MOA adjustments as normal.
2. Once satisfied with the zero determine how many ¼ MOA clicks you would like to
have “Below” the current zero. For example, if the rifle is zeroed at 100 yards
you may want an additional 4 clicks (1 MOA) of depression below the existing
zero. This will allow you to adjust below your normal zero if necessary. If the
rifle is zeroed at 300 yards you may want more depression capability. Determine
what you need for field use.
