6. UNIT ADJUSTMENT ON THE RIFLE
The adjustment of the scope should be performed either in the daytime with the lens
cap on or in the twilight using an adjusted target or a remote point.
6.1 Reticle
Unit has a reticle shown on Figure 3.
The distances between dots are given in meters at 100
m range. For ranges other than 100m the distances must
be calculated proportionally.
Brightness of the reticle may be adjusted by the knob
(8, Fig.1).
6.2 Adjustment procedure
Attach the unit to the rifle. Prior to adjusting the
scope its objective should be focused on the target.
Set up a panel with a target at 100 m.
Set the rifle on the gun rest to eliminate human error as much as possible.
Making certain the rifle is empty with no cartridge in the chamber and the breech is
open, install the mechanical or laser bore sighter. Install laser bore sighter in the
muzzle of your rifle lining it up with the scope as close as possible.
Looking through the scope as though you were going to shoot you should see
reticle produced by the unit and a cross hair produced by the bore sighter. They
should line up with each other vertically, horizontally and be in complete
alignment. If they are not parallel to each other, adjust the bore sighter in the
chamber.
Unscrew the protective caps of the reticle adjustment screws. Turning those screws
match reticle crosshairs with the aimed point, provided by the mechanical sight or
laser bore sighter.
Remove the bore sighter from the muzzle. Make 2-3 shots. Having examined the
target, make necessary corrections. For example, in order to move the hit point
downwards and leftwards, adjustment screw should be turned counter-clockwise,
in the Down and Left directions. The aiming point will move upwards and
rightwards correspondingly.
If you do not hit the paper target at all, move the target closer until you consistently
hit somewhere on the target. You cannot make any scope adjustments if you do not
know which direction to make it. Do not be concerned if you did not hit the bull’s
eye. Once you initially hit the target sheet you can make adjustments and then
gradually move the target back out to the 100 yard mark.
When the desired precision is achieved set the protective caps into their places.
The unit is now ready for operation.
