Instruction Manual

for

POSP 4x24 / PSO-1

Rifle scopes

1. NTRODUCTION

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 updated the actual scope may slightly differ from this manual.
The scope can be used in a variety of climatic conditions with temperatures ranging from -50°C...+50°C (-50°F…+120°F)
The scope is also sealed against sand and dust as well as filled with Nitrogen to prevent fogging.

4.2 Mounting the scope

The scope has a built-in mount that can be equipped with three different types of clamps designed to mount on different
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, as some mounting clamp are not designed to accept certain types of rails.
PLEASE NOTE, that by "not designed to accept certain types of rails" we mean the configuration of the rail and NOT its
size, as 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 not enough of eye relief, or the scope won't hold its "zero" if removed. 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 matter how tight it is locked.
To avoid this, you should learn about the three types of Russian rifle scope clamps and which rails should be 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 daylight scopes. This type of mount is universal and will properly fit all 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't allow 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 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. REMEMBER that the scopes with the AK/Saiga
type of mounting clamp will properly fit the plate on your rifle ONLY if the plate has a CLOSED right end
of the rail.

To mount the scope release the locking lever and align the rail on your gun with mounting clamp, slide the scope forward
on the rail until it stops. Close the locking clamp. If the scope can not slide along the rail or the locking lever can not be
closed with reasonable force the mounting clamp has to be adjusted. 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
INTSRUCTIONS BELLOW

Locate the locking clamp assembly, (see picture on the left). 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
tightness of the locking mechanism. To adjust the clamp, turn the
scope up side down, presses 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.

5. Sighting and Zeroing the Scope

Tightly secure the gun at the firing station using sandbags or special sighting rack to avoid shooter related inaccuracy.
Using your iron sights fire 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 and the elevation turrets. If during sighting process you run out of adjustment room on either the
windage or the elevation turret do the following: Loosen two screws located on the top of the turret and turn the black, top
part of the turret without touching the 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 compare the API with the previous group of shots if the result are
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 actual “0” on the elevation cam. Please refer to the table bellow to see where the actual “zero” is on your scope.
