ZEROING

 

  

Detailed zeroing is provided later in this manual.  The following procedure is provided for users 
familiar with optical sight zeroing. 

  Azimuth zeroing uses the windage screw found at the front of the mount.  Rotate the front left 

windage screw clockwise to move the point of impact to the left; counter clockwise to move to 
the right. Each click of the windage screw moves the point of impact by one-half MOA 
(approximately 1/2” at 100 yards). Figure 2-4

 

  Elevation zeroing uses the elevation dial the bottom rear of the mount.  Unlock the zeroing 

lock (silver tab) by raising it up as far as it will go.  

Be sure that the lock pin at the bottom 

of the zeroing lock is fully disengaged from the elevation dial. 

  Adjust the elevation dial as required. Each click of the elevation dial moves the point of 

impact by one-half MOA (approximately 1/2” at 100 yards). Turn the dial to the 

R

  When satisfied with elevation zero, lower the zeroing lock (silver tab) fully to lock the 

elevation zero at its current setting.
