3. Instructions
(1) Focusing
1 Look through the eyepiece with your eye positioned about 4 in. (10 cm) away from the eyepiece to see the BDC 800 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.
Notice: Reticle images shown in this manual are representation only. Actual images may vary.

(2) Magnication
• 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.
Note:
• The windage and elevation scales of P-TACTICAL .308 riescopes are calibrated in divisions of 1/4 minute of angle (MOA) with a click at intervals of 1/4 minute of angle.
• 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
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 800 reticle
BDC 800 reticle
The BDC 800 reticle was designed specically for long range, heavy barrel AR platform ries using .308 Winchester with 168 grain hollow point
boat tail match grade ammunition with an approximate muzzle velocity of 2680 fps (feet per second) (817 m/s). The reticle is designed for
100 yd. (91m) zero, with alternating circles, hash marks and dots that provide multiple bullet drop compensation aiming points out to 800 yd.
(732m) using the ammunition specied above. The circles represent even number yardages 200, 400, 600 and 800 yd. (183 m, 366 m, 549 m,
732 m) while the dots represent odd number yardages 300, 500 and 700 yd. (274 m, 457 m, 640 m) with the hash marks representing 50 yd.
(46 m) increments between the circles and dots 250, 350, 450, 550, 650 and 750 yd. (229 m, 320 m, 411 m, 503 m, 594 m, 686 m)
Please note the hash mark below the bottom circle as well as the pointed bottom vertical post can also be used for additional points of bullet
drop compensation.
Please note that your rearm may or may not match the information listed for bullet drop based upon the variables listed in this section.
What if your choice of round in your AR rie is a .308 Winchester 150 grain bullet at 2800 fps (feet per second) (853 m/s) or a caliber other
than the .308 Winchester? 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 hash
mark represents, providing unparalleled ballistic data for long range shooting.

The Spot On website has been designed to provide accurate information that matches the ballistics of whatever projectile you are shooting directly to the reticle.
Please note that you should verify that your set up matches the information provided in this manual or the Spot On program before venturing into the eld. The only way to truly verify the information is by actual shooting.
Again, the variables listed above may or may not aect the results.
Note: It is imperative that the reticle be level in relation to the rearm. If the reticle is canted, even just a few degrees, it can cause the shot to drift o the centerline of the point of aim. There are many commercial leveling
devices on the market, but the one that we nd to be the most accurate in leveling the reticle is a plum bob. Use a bubble level to make sure the rearm is level, then look through scope at an appropriately placed plumb
bob and align the reticle accordingly.
Please also note that all Nikon BDC reticles were originally designed to be used on the highest magnication. Since changing the magnication changes the position of the circles in relation to the target, the distances
listed along with each of the illustrations are at the highest magnication. The center crosshair does not change with magnication as it is placed in the optical center of the scope.
The benet of the Spot On program is that it calculates the distance that each circle represents at every magnication.
If you have further questions regarding the Spot On Technology please visit the website: http://spoton.nikonsportoptics.com/spoton/questions.html
Note:
Spot On is available only in the US and Canada.
