To adjust windage: Unlock the eyedisc and turn the
knurled windage knob on the right side of the eyedisc. Each
mark on the windage scale is spaced 0.020" (2 minutes of
angle...MOA). By moving the single mark in between windage
marks, adjustments as fine as 1 MOA are possible.
By keeping a log of settings for appropriate ranges, a
shooter can return to any known setting with 1 MOA
repeatable accuracy.
To adjust elevation: Unlock the eyedisc and turn
the knurled knob at the top of the staff assembly. Elevation
is calibrated in .010" increments (1 MOA). The elevation
scale on the staff is marked in .050" increments with
numeric / fractional marks at .500" increments.
Example: 1/2 - 1 - 1/2 - 2, etc. Each mark on the
elevation slide scale is spaced 0.040". When the top and
bottom marks on the elevation slide are aligned with marks
on the staff, the four center marks are out of alignment. If
the elevation slide is moved .010" up or down only one mark
will be inline with a mark on the staff.
Example: Move the elevation slide up or down until the
bottom mark is inline with the 0" mark on the staff. This is
your 0.000 setting. Move the elevation slide up until the
next mark on the elevation slide is aligned with a mark on
the staff. This is a 1 MOA adjustment. The sight setting is
now 0.010". Repeat the process until the bottom line is in
alignment with the next line on the staff. This setting
would be 0.050".
