Ruger MINI-14 - Manual (Page 31)

32
The rear sight is adjustable for both windage and elevation. A small punch, the
head of a finishing nail, or other similar instrument can be used to depress the
plunger to allow the adjustment to be moved one quarter turn in either
direction. One quarter turn will move the point of impact 1 inch at 100 yards.
The sight adjustments have been made deliberately positive by means of spring-
loaded detent plungers so that settings cannot be accidentally disturbed under
normal conditions.
WINDAGE ADJUSTMENT: To move the bullet impact point to the right, move
the rear sight base to the right by turning the adjustment knob
counterclockwise. To move the bullet impact point to the left, move the rear
sight base to the left by turning the side adjustment knob clockwise.
ELEVATION ADJUSTMENT: To move the bullet impact point up, move the
elevation slide (the “peep”) up by turning the top adjustment knob
counterclockwise. To move the bullet impact point down, move the elevation
slide down by turning the top adjustment knob clockwise.
