Congratulations on your choice of a Nikon riescope. Your new scope is the nest example of Nikon’s rugged and durable construction and precision bright optics; important qualities for a serious shooter’s riescope.
Whether you use your scope for target shooting or for hunting, the procedure for mounting is identical. A set of high-quality steel mounting rings which have a standard diameter of 25.4 mm (1 in.) are required to mount

En

the scope. Follow the ring manufacturer’s instructions for mounting procedures. After mounting the scope on your rie, follow the procedures for reticle alignment.

WARNING:

IMPROPER MOUNTING OF YOUR NIKON SCOPE CAN CAUSE SERIOUS INJURY.
THUS IT IS IMPORTANT THAT YOUR NIKON SCOPE IS MOUNTED PROPERLY BEFORE USING. TO ENSURE PROPER MOUNTING OF YOUR NIKON SCOPE, PLEASE HAVE IT MOUNTED AND/OR CHECKED BY AN EXPERIENCED
GUNSMITH BEFORE USING.
THE USER ASSUMES ALL RESPONSIBILITY AND LIABILITY FOR HAVING THE SCOPE PROPERLY MOUNTED TO A FIREARM AND FOR USING THE SCOPE PROPERLY.
ALWAYS CHECK THE CONDITION OF YOUR SCOPE AND YOUR MOUNTING SYSTEM BEFORE USING YOUR FIREARM.

Caution

(1) Do NOT look at the sun through the riescope. It will permanently damage your eye. This precaution applies to all optical devices, such as cameras and binoculars.
(2) The riescope is eectively sealed against moisture and dust. You may use your scope safely either in the rain or in dusty climates. To preserve the appearance of the scope, we recommend that it be dried and

cleaned prior to storage. Use a soft cloth for cleaning metal surfaces and use photographic lens tissue to clean the scope’s lenses.

Notice for customers in the State of California
WARNING: This product contains chemicals including Lead which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to

www.P65Warnings.ca.gov.

When setting the reticle for shooting or 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, according to
personal preference, 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.
We hope that you will enjoy your new Nikon Riescope for many years to come. Enjoy using it, and above all, always follow safe shooting procedures.

3. Instructions

(1) Focusing

1 Look through the eyepiece with your eye positioned about 10 cm (4 in.) away from the eyepiece to see each reticle (Fig. 3).

Be sure your eye is positioned with proper alignment and with proper eye relief, otherwise the view will “black out.”

2 Point the objective end of the scope at the sky (do NOT point it at the sun) or at a plain unpatterned wall.

Standard BDC reticle

Nikoplex (Duplex) reticle

3 Turn the eyepiece adjustment counter-clockwise and then turn it clockwise until the reticle appears sharp.

Notice: Reticle images shown in this manual are representation only. Actual images may vary.

(2) Magnication

• Nikon riescopes have variable magnication. For details, see “2. Specications”.

To change powers, rotate the power selector ring until the desired magnication appears adjacent to the power index.

(3) Adjustment of the riescope

Sighting through the riescope, align the rie 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 adjustment turrets as follows:

• If the bullet hits under the aiming point, turn the elevation adjustment turret (counter-clockwise) in the direction of the arrow marked “U” for up. If the bullet hits high, turn the elevation adjustment turret (clock-

wise) in the direction of the arrow marked “D” for down.

• If the bullet hits to the right of the aiming point, turn the windage adjustment turret (clockwise) in the direction of the arrow marked “L” for left. If the bullet hits to the left of the aiming point, turn the windage

adjustment turret (counter-clockwise) in the direction of the arrow marked “R” for right.

• After the reticle has been adjusted to the point of impact, replace the turret cap for both the elevation and windage adjustment turrets.

Note:

• The windage and elevation scales of PROSTAFF P3 riescopes are calibrated in divisions of 1/4 minute of angle (MOA) with a click at intervals of 1/4 minute of angle (1 division).

• When adjusting the reticle to the point of aim, remember that 1 minute of angle equals approximately 2.54 cm (1 in.) at 91.44 m (100 yd.).

Therefore, if the impact point is 5.08 cm (2 in.) low and 2.54 cm (1 in.) right at 91.44 m (100 yd.) parallax setting, you should adjust 2 minutes of angle up and 1 minute of angle left.
In the case of 45.72 m (50 yd.) parallax setting, the adjusting value is 2×. In the case of 68.58 m (75 yd.) parallax setting, the adjusting value is 1.5×.
