The windage knob features large and small index
marks on the right side. Rotating the assembly from
one large mark to the next results in
1
⁄2 minute of angle
of adjustment. Moving from a large mark to the
nearest small index provides
1
⁄4 minute of angle of
adjustment. One entire revolution of the windage knob
equals 2
1
⁄2 minutes of angle.
Elevation (vertical adjustment): Adjustments are made
by turning the elevation knob. IMPORTANT: Before
making any vertical adjustment of the elevator, be sure
to loosen the sight disk a half a turn.
Failure to do so
will result in damage to the sight.
The rear sight ladder, or staff, is indexed in increments
of 5 minutes of angle. The elevator is indexed in
increments of 1 minute of angle. In Figure 6, the sight
is set for 25 minutes of angle. Note how the smaller
index marks on the elevator do not align themselves
with any index mark on the staff at this point.
To move the elevator up one minute of angle (to 26),
turn the elevation knob clockwise until the first small
index mark on the elevator aligns with the “30” index
mark on the staff (Figure 7). To continue an additional
minute of angle (to 27), turn the elevation knob until
the second small index mark on the elevator aligns
