    1. INTRODUCTION


Before using the scope carefully read this instruction manual.The scope is equipped with built-in
mount that can incorporate three different types of clamps designed to mount on distinct types of rails.
Before attempting to mount the scope learn which type of mount your plate will accept as it is crucial for proper 
function of the scope.The scope is designed with extended eye relief and has a rangefinding capability.
Red illuminated reticule will ensure target acquisition at low light conditions.As the design constantly being 
umpated the actual scope may slightly differ from -50 C..+50 C(-50 F..+120 F).The scope is also 
sealed against sand and dust as well Nitrogen to prevent fogging.

    3.GENERAL DESCRIPTION

4.1 Inserting\ Replacing the Battery.

The scope is quipped with reticule illumination system that uses two #357 silver-oxide batteries.
Radio Shack carries these and they are Radio Shack #23-105.To replace battery remove cover from the
battery compartment,by pressing it down and twisting it counter clockwise.
Install new battery keeping the polarity,close the battery compartment.The battery goes in counter-
intuitively.The side with the writing,the+side, goes in first.If reticule looses its brightness over time, 
replace the battery.


4.2 Mounting the scope.

The scope has a built-in mount that can be equipped with three different types of clamps different
to mount on different types of tails.Before attempting to mount the scope learn which type of mount 
your plate will accept as it is crucial for proper function of the scope,as some mounting clamp are
not designed to accept certain types of rails.
99.99% of the scopes,if properly adjusted(please see 4.2.1),will fit the bulk majority of the mounting rails found
on AK family of guns.Thus,it might be possible to mount the scope on the gun,you may encounter such
problems,as too much or notenough of eye relief,or the scope won^t hold its *zero* if rem oved.
Often you can tell that the scope isn^t designed to fit the rail on your gun by mounting the scope
and firing a few shots.If the clamp on your scope doesn^t match the rail,the scope will fall off after the third
or fourth shot,no matterhow tight it is locked.To avoid this,you should learn about the three types of Russian 
rifle scope clamps and which rails should he used with each type of clamp.
A.Russian Standard Small Arms Mounting System clamp,used on all of the Night Vision Rifle Scopes and
some day light scopes.This type of mountis universal and will property fitall types of mounting plates.
B.PSO-1 or Dragunov style mount found on the PSO/POSP rifle scopes.This type of mounting clamp has a forward
placed stopping pin.The clamp moves all the way forward on the rail until the stopping pin comes to rest
at the closed end of the rail REMEMBER that the scopes with the PSO-type of mounting clamp will properly
fit the plate on your rifle ONLY if the front end of the rail is CLOSED.This won^tallow the scope to come
off at the other end of the rail and the scope will always retain its *zero*.
C.Saiga/AK type of the mounting clamp has the rear placed stopping pin and designed to fit mounting plates
found on AK,Saiga and Vepr rifles.The clamp has to slide forward on the rail until it stops as the pin
comes against the back(right) end of the mounting plate.REMEMBERthat the scopes with the AK/Saiga type
of mounting clamp will property fit the plate on your rifle ONLY if the has a CLOSED right end of the rail.
To mount the scope release the locking clamp.If the scope can notslide along the rail or the locking lever
can not be closed with reaso nable force the mounting clamp has to be aadjusted.Adjustment might be  needed
if the scope sits too loosely.

4.2.1 Locking clamp adjustment.

      LOCKING CLAMP ADJUSTMENT REQUIRES NO SPECIAL TOOLS OR SKILLS, PLEASE READ THE INSTRUCTIONS BELOW.           

The locking assembly consists out of the locking rail(1) round adjustment nut(2),spring(3) and the
locking lever(4).The round nut controls the tighthness of the locking mechanism.To adjust the clamp,
turn the scope up side down,press down and hold the locking rail(1) with the thumb of your left hand.
With your right hand adjust the nut(2)by turning it.Turn the nut clockwise to tighten the mount and
counterclockwise to loosen it up.


4.2.2 Clamp Adjustment-In-depth.

Step1:Invert the sight and notice the retaining clip that is holding the lever onto the sight.Place
a small screwdriver blade on the edge of the retaining clip,and by using the thumb lever as a pivot,
rotate the retainer out of it^s detent.In the field, you can hold the sight steady by placing it between
your knees.
Step2:Once the retaining clip is rotated 90 degrees,you can easily slide it of the center shaft of the
clamp lever.It will now pull off of the sight.
Step3:Once the clip is removed, you can disengage the lever from it^s gear on the center shaft be sure
not to lose the clip or the washer uderneath the lever.
Step4:With the sight mounted to the rifle,re-position the lever until you can obtain a tight fit on the
weapon optics side plate.Do not overtighten.
Step5:Once the proper tension is obtained,replace the lever onto the gear,making sure to relocate the stem
of the bushing arm in the lever flag.Also make sure you have not lost the special washer that fits under 
the lever.
Step6:Now,replace the lever retaining clip,by inserting the center shaft into the large hole in the clip.
Step7:Now simply slide the clip hack into the detent.Try the fit, make sure the sight will slide onto 
the plate easily,and will also tighteu up.There should be a moderate amount of tension on the lever
when it is about 85 perceht the tension if need and it should take mild pressure to lock it completery.
Do not overtighten.Repeat the procedure to adjust the tension if needed.


5.Sighting and Zeroing the Scope.

Tightly secure the gun at the firing station using sandbags or special sighting rack in avoid shooter related
inaccuracy.Using your iron sights 4-5 shot group.Without moving the rifle look through the scope and
determine average point of impact(API).One or two shot may deviate,this it is normal,disregard those
shots.Make necessary adjustments to the scope using the windage snd the elevation turrets.If during sighting
process you run out of adjustment room on either the windage or the elevaition turret do the following:
Loosen two screws located on the top of the turret and turn the black,top part of the turret without 
touchingthe silver cam.Once the reticule is in the required position stop turning the top part of the 
turret and now move the silver cam somewhere to the middle of the scale relative to the dash mark
on the scope.After adjusting the reticule,fire a few more control shots and com pare the API with the
previous group of shots if the resultate the same the scope is sighted.Now you will have to put the 
elevation cam to *zero* position which in some cases may not be the acmal *0* on the elevation cam.
Please refer to the table bellow to see where the actual *zero* is on your scope.To adjust the elevation
cam to *zero* position loosen the two screms on the top of the turret and carefully move the cam to
properposition.Tighten the screms.


5.1  Elevation turret

There are at least two different elevation turrets that come with POSP/PO/PSO tyre scopes.One has an uneven
scale num bered 0 to 10 with different number of clicks between the numbers.The other turret has a seale 
from 0 to 20 with evenly incremented clicks.Bellow are two tables that will give you a rough idea on how 
to us e the both tyres of turrets to make adjustments for the bullet drop at distances between 100 and 850
meters.After 850 meters you^ll have to use the consequently following chevrons for each 100 m of the 
distance for up to 1200 meters.Remember that the data in these tables is estimated as the actual
bullet drop depends on many other factors,such as the ammo,rifle,surrounding environment,air temperature,
and etc.Also,the bullet drop compensation presented in these tables is for 7.62x54R and with some minor
adjustments the  308 round can also be use.If you have a scope with 400m range-finding reticule it is
calibrated for 7.62x39 round.In this case you should use the chevrons to compensate for each 100m of the
distance for up to 300m.

5.2 Using the scope
5.2.1 White aiming you must put your eye on the optical axis of the scope so the image appears flat and
     without shadows on the edges.Using soft rubber eyepiece will help you to property  align your eye 
     on the optical axis and ensure the proper eye relief.
5.2.2 Use the extendable shade for shooting at bright daylight conditions to prevent sunshine directly
    striking the objective lens and preventing excessive glare.

5.3 Aiming and shooting at fixed targets.
5.3.1 Adjust the elevation turret or chose the appropriate chevron with respect to the range to the 
    target.Assuming there is no cross wind,keep the windage turret at the ^0^ position.
5.4 Aiming and shooting atmoving targets.
5.4.1 While shooting at moving targets it is necessary to aim ahead of the target.
5.4.2 To determine how far the aiming point has to be taken out you^ll need to estimate the speed
    of the target and the distance to it the father ahead you^ll have to aim.
5.4.3 Have the moving target aligned with horizontal hairs of the reticule as you aiming.

6. SAFEKEEPING

6.1 Avoid hard strikes to the scope or dropping it.

 8.    RETICULE FOR 7.62x54R

8.1 Rangefinder
8.1 The rengefinder works by plaicing the target(1.7m or 5.8 in height)between the horisontal and the tup
   reclining line with numbers.On the reclining line locate the number closest to the point where the target to 
   uches the line.Multiply that number by 100,this is the target in 1 metes=1.11 yards.
8.2 Windage scale/rangefinder.
   Windage scale can he used to make horisontal adjustments or as a rangefinder.Shifting the aiming point
   by one division left or right will move the point of impact by 10cm/4 for every 100m/333ft of the distance.
   The distance to the target can be determined by assuming that a 1m/3,4 wide/long object fits between the small
   divisions at 100m/333ft.
8.3 Aiming chevrons
   The chevrons designed to adjust for buller drop at 1000,1100 and 1200 meters,aiming with 2nd,3rd and the 4th
   chevrons accordingiy.


9.RETICULE FOR 7.62x39
9.1 Rangerefinder
   The rangerfinder works by placing the target(1m or 3.4 in height)between the horizontal and the top reclining
   line with numbers.On the reclining line locate the number closest to the point where the tagret touches the line.
   Multiply that number by 100,this is the distance to the target in meters.1 meter=1.11 yards.
9.2 Aiming Chevrons
   The chevrons designed for aiming at 100,200 and 300 meters for the lst 2nd and 3rd chevron accordingly.
9.3 Windage scule/Rengefinder
   Windage scale can be used to make horizontal adjustments or as a rangefinder.Shifting the aiming point by one
   division left or right will move the point of impact by 10cm/4 for every 100m/333 gt of the distance.The
   distance to the tagret can be determined by assuming that a 1m/3.4 wide/long object fits between the small
   divisions at 100m/333ft.
