OMEGA Muzzleloading Riflescope 3-9x40
Instruction manual
Congratulations on your choice of a Nikon OMEGA Muzzleloading Riflescope.
Your new scope is the finest example of Nikon’s rugged and durable
construction and precision bright optics; important qualities for a serious
shooter’s riflescope.
Whether you use your scope for hunting or for target shooting, the procedure for
mounting is identical. You should acquire a set of high quality steel mounting
rings which have a standard diameter of 25.4 mm (1 inch). Follow the ring
manufacturer’s instructions for mounting procedures. After mounting the scope
on your muzzleloader, follow the procedures for reticle alignment.
When setting the reticle for hunting, you should determine your standard range
and then adjust the reticle based upon that target distance. For targets which
vary from that standard distance you may simply adjust the position of the
reticle in relation to your target, or you may wish to use the procedure for
trajectory compensation. It’s up to your personal preference.
We hope that you will enjoy your new Nikon OMEGA Muzzleloading Riflescope
for many years to come. Enjoy using it, and above all, always follow safe
shooting procedures!

your scope safely either in the rain or in dusty climates. To preserve the

3. Instructions
(1) Focusing
Look through the eyepiece with your eye positioned about 10cm (4 in) away
from the eyepiece lens (Fig. 3-1), and you will see the Nikoplex reticle (Fig. 3-2),
or the BDC250 reticle (Fig. 3-3).
Be sure your eye is positioned within proper alignment and proper eye relief
otherwise the view will “black out”.
Point the objective end of the scope at the sky (Do not point at the sun) or at a
plain unpatterned wall.
Turn the eyepiece adjustment counter-clockwise and then turn it clockwise until
the reticle appears sharp.
(2) Magnification
The OMEGA Riflescope 3-9x40 has a variable magnification for 3 to 9X.
To change powers, just rotate the power selector ring until the desired
magnification appears adjacent to the power index dot (Fig. 1-1).
(3) Adjustment of the riflescope
Sighting through the riflescope, align the rifle with your aiming point on the
target and shoot a trial round. If the bullet does not hit the aiming point, adjust
the elevation and windage after removing the Adjustment cap, as follows:
For the OMEGA Riflescope adjustment is made by turning the grip by hand. If
the bullet hits under the aiming point, turn the grip in the direction of the arrow
marked “U” (Fig. 3-4). If the bullet hits to the left of the aiming point, turn the grip
in the direction of the arrow marked “R” (Fig. 3-4).
Note:
• The windage and elevation scales of the OMEGA Riflescope 3-9x40 are
calibrated in divisions of minute of angle with a click at intervals of minute
of angle (half division).
• When adjusting the reticle to the point of aim, remember that one minute of
angle equals approximately one inch (2.54 cm) at 100 yards (91.44 m).
Therefore, if the impact point is two inches (5.08 cm) low and one inch (2.54 cm)
right at 100 yards (91.44 m), you should adjust two minutes of angle up one
minute of angle left.
Maintenance
(1) Lens cleaning
To remove dirt or fingerprint, soak gauze or lens cleaning paper (silicon-free
paper sold at camera shop) with a small quantity of absolute alcohol (available
from drugstore) and lightly wipe off. Wiping with leather chamois is not
recommended as it is likely to damage the lens surface.
Dust may scratch the lens surface or corrode the lens.
Brush dust off using a soft oil-free brush.
(2) Scope Exterior
Use a soft dry cloth to wipe off any dirt or fingerprints that might accumulate.
It is not necessary to oil the scope’s surface.
(3) Windage/Elevation Adjustments
These adjustments are permanently lubricated. Do not attempt to lubricate
them. Cover with caps supplied, except when adjusting, to keep out dust and
dirt.
(4) Eyepiece Adjustment
This adjustment is permanently lubricated. Do not attempt to lubricate.
(5) Power Selector Ring
No lubrication is required on the power selector ring.
Do not loosen or remove screws in the power selector ring.
