Congratulations on your choice of a Nikon M-223 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 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 Rifle, 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 M-223 Riflescope for many years to come. Enjoy using it, and above all, always follow safe shooting procedures!

Caution

(1) Do not look at the sun through the riflescope. It will permanently damage your eye. This precaution applies to all optical devices such as

cameras and binoculars.

(2) The riflescope is effectively 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 suggest 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.

The product(s) described herein may be subject to export control regulations in the relevant country(ies). It (they) should not be exported without authorization of the exporting govermental authority if the regulations apply.

(2) Magnification

●The M-223 Riflescope 3-12x42 has a variable magnification from 3 to 12x, 2-8x32 from 2 to 8x and 1-4x20 from 1 to 4x.

●To change powers, just rotate the power selector ring until the desired magnification appears adjacent to the power index dot (Fig. 1-1, 1-

2, 1-3).

(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 as follows: For the M-223 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". If the bullet hits to the left of the aiming point, turn the grip in the direction of the arrow marked "R".

(4) Adjustable Parallax setting

The M-223 Riflescope 3-12x42 SF can be more precisely focused within the range of at least 50 yards (45.72m) - infinity by rotating the side focus adjustment. Parallax can be eliminated and sight alignment will be accurate. Use it's distance scale as a reference guide. The adjusting ring has a lock system, so that it will not move during shooting. When adjusting the focus, pull out the adjusting ring. For lock push in the adjusting ring. (Fig. 3-5 )

Note:

●

The windage and elevation scales of the M-223 Riflescope are calibrated in divisions of 1/4 minute of angle with a click at intervals of 1/4

minute of angle.

●

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.

(5) Zero setting of scale grip

The adjusting ring has a pop-up zero adjusting system. After the reticle has been adjusted to the point of impact, for zero setting pull out the adjusting ring. The adjusting ring can turn freely now, and align the zero number to index line, then push in the adjusting ring to set. (Fig. 3-5 )

(6) 100 yards setting of Rapid Action Turret

The Rapid Action Turret has a pop-up zero adjusting system. After the reticle has been adjusted to the point of inpacts at 100 yards, for 100 yards setting pull out the Rapid Action Turret. The Rapid Action Turret can turn freely now, and align the 100 number to index line, then push in the Turret to set.

(7) Pop-up Zero / 100 yds setting and Focus adjusting system

Side focus knob and Elevation and windage adjusting knob has a pop-up setting / locking system.
