Congratulations on your choice of a Nikon riescope. 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 riescope.
En
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 1 in. (25.4 mm) are required to mount

the scope. Follow the ring manufacturer’s instructions for mounting procedures. After mounting the scope on your rie, 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 riescope. It will permanently damage your eye. This precaution applies to all optical devices, such as cameras and binoculars.
(2) The riescope is eectively 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 Riescope 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 4 in. (10 cm) 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.

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

(2) Magnication
En
• Nikon riescopes have variable magnication. For details, see “2. Specications”.
To change powers, rotate the power selector ring until the desired magnication appears adjacent to the power index.
(3) Adjustment of the riescope
Sighting through the riescope, align the rie 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 riescopes 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 1 in. (2.54 cm) at 100 yd. (91.44 m).
Therefore, if the impact point is 2 in. (5.08 cm) low and 1 in. (2.54 cm) right at 100 yd. (91.44 m) parallax setting, you should adjust 2 minutes of angle up and 1 minute of angle left.
In the case of 50 yd. (45.72 m) parallax setting, the adjusting value is 2×. In the case of 75 yd. (68.58 m) parallax setting, the adjusting value is 1.5×.

(4) Zero resetting of adjustment turret
The elevation adjustment and windage adjustment turrets have a retracting system. After the reticle has been adjusted to match the point of impact, pull up the elevation adjustment or windage adjustment turret
to disengage. The turret can now be turned freely. Align the zero number to the index line to set the zero setting, and then release the turret. The turret automatically retracts to the original position.

Utilizing the BDC reticle
Thank you for choosing the Nikon BDC reticle riescope. The BDC reticle is designed to compensate for the trajectory of your rearm. Regardless of the particular style of BDC reticle you have, the position of the circles are
En
based upon an average trajectory for some of the more popular projectiles and cartridges on the market based upon the intended use of the scope itself.
Please note that the reticle is based upon ballistic information and may or may not meet the same results for you as there are many variables that come into play such as:
• Actual Velocity (Ammunition manufactures’ information in regards to muzzle velocity may or may not match the velocity your rearm produces. The best way to determine the actual muzzle velocity for your rearm
is to use a chronograph).
• Temperature
• Humidity
• Altitude
• Barometric Pressure
• Condition and inherent accuracy of the rearm
• The mounting system and how true it positions the scope to the centerline of the bore

BDC 200 reticle
The BDC 200 reticle was designed for use with modern, high velocity sabot style slugs when used in fully ried slug guns. We recommend using slugs that have an aero-dynamic polymer tip design as these have a higher
ballistic co-ecient and provide atter trajectory over longer ranges.
The BDC 200 reticle is designed to be zeroed at 50 yards with a polymer tipped slug with an approximate muzzle velocity of 1900 fps. The reticle would then provide bullet drop compensation for 100, 150, 175 and 200
yards using the respective ballistic circles as shown on the next page.

En
Please note that your rearm may or may not match the information listed for bullet drop based upon the variables listed in this section.
En
Note:
We highly recommend that you try various brands of ammunition to see what round is the most accurate in your respective slug gun.
What if you prefer to shoot a full bore diameter Foster type slug, or prefer to zero your rearm at 100 yards? NO PROBLEM, just go to the
Nikon Spot On website (nikonsportoptics.com/Spoton) and you can match your exact cartridge to the reticle. In fact, we highly recommend
that you check out the Spot On website as it will provide exact yardages that each circle represents, providing unparalleled ballistic data
for long range shooting.
