the reticle at a plumb line. Align the vertical cross hair of the reticle with the plumb line by rotating
the scope within the rings. Once you are satisfied with your scopes setting and placement tighten
the rings evenly and securely according to the Manufactures Specifications. Be sure not to over
tighten the rings, as doing so can cause permanent damage to the scope.
Focusing Your Scope

CAUTION: VIEWING THE SUN WITH THIS SCOPE OR ANY OTHER OPTICAL
DEVICE CAN CAUSE PERMANENT INJURY TO THE EYE INCLUDING BLINDNESS
For compact tactical scopes with the quick focus ring feature, follow these next
instructions:
Holding the scope at the proper distance from your eye, in order to achieve a Full Field of View,
the reticle should appear sharp and clear. If not, it will be necessary to adjust the focus by turning
the Quick Focus Ring.
1. Make quick glances through the eyepiece at a
featureless bright surface such as a white wall, or
the open sky.
2. Turning the Quick Focus Ring counter-clockwise will
extend the Ocular Lens outward, generally suitable
for those who are far sighted. Turning the Quick
Focus Ring clockwise will draw the Ocular Lens
inward, generally suitable for those who are near
sighted.
3. Fine tune your adjustments until the reticle appears
sharp and clear. If the Ocular Lens reaches its
outer limits of adjustment, be sure not to force it as
doing so will cause damage to the eyepiece.
For compact tactical scopes with the adjustable ocular bell housing focus feature, follow
these instructions:
Just in front of Ocular Bell Housing you will find a knurled ring that is the Lock Ring. With scope
models with Variable Magnification, the Lock Ring will be located between the Ocular Bell Housing
and the Magnification Ring.
1. This Lock Ring loosens by turning the Lock Ring Clockwise. With the Lock Ring loosened, you
can then turn the Ocular Bell Housing to adjust the Reticle Focus.
2. Make quick glances through the eyepiece at a featureless bright surface such as a white wall,
or the open sky.
3. Turning the Ocular Bell Housing Counter-Clockwise will extend the Ocular Lens outward,
generally suitable for those who are far sighted. Be careful to not turn the Ocular Bell Housing
too far out, as it can come free from the scope body, breaking the O-Ring nitrogen seal. Don’t
go more than 3 to 4 full revolution Counter-Clockwise from the factory position.
