Octagon Scope Series Features
Mounting Your Scope
CAUTION: BE SURE THAT YOUR FIREARM IS UNLOADED AND POINTED IN A SAFE
onto your optics rail on your firearm. This will allow you to space out the rings properly, for the ring
mounting bolts to match up with the cross slots of the optics rail. Once you have the scope rings
mounted onto your optics rail, you will next have to move the scope forwards or rearwards to adjust
the scope’s position to allow for Maximum Eye Relief and reticle leveling. Slide the scope as far
forward as possible in the rings. While viewing through the scope in a normal shooting position
move the scope back towards your eye until a Full Field of View is achieved while ensuring that the
scope will be a safe distance from your eye when the firearm recoils. Without disturbing the Eye
DIRECTION. PRACTICE SAFE FIREARMS HANDLING PROCEDURES AT ALL TIMES.
NOTE: IF YOU ARE UNFAMILIAR WITH THE PROCESS OF SCOPE MOUNTING IT MAY
BE NECESSARY TO EMPLOY THE SERVICE OF A QUALIFIED GUNSMITH.

Relief setting aim 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 settings and
placement, tighten the rings screws evenly and securely to approximately 10 to 15 inch lbs. of
torque (Not foot lbs.) with an inch pound torque wrench/screw driver. 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
Octagon scopes have a quick focus ring feature:
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.

Adjustment Dials which change your scopes point of aim
relative to the bullet point of impact on a target for a specific
range. The Elevation Adjustment Dial is located on top of the
Turret Body, and is responsible for the up and down
movement of the reticle.
