There are two knurled nuts which adjust the sight for elevation and windage, both on the vertical post. The lower and shorter nut allows adjustment for windage. By loosening it (counter clockwise 1/4 turn), you can move the windage cylinder from side to side through the pivot block. When the desired setting is attained, turning the nut clockwise will tighten it.

     Elevation adjustment is achieved by turning the upper, longer nut to raise or lower the aperture post. When sights are new they are often tight. Be patient and careful in your adjustments. The aperture post (which holds the eyepiece) will come out if the elevation nut is screwed too far.

     Tension on the pivot motion of the sight, from down (resting parallel to the tang) to up (in sighting position) and back, may be adjusted by the pivot screw which holds the pivot block to the sight base. Within the block and the ears of the base is a ball detent which snaps into place at the proper sighting angle.
