2.6. Disassembly and assembly of rifle
2.6.1. The disassembly of the sniper rifle may he partial and complete:
partial disassembly is performed for cleaning, oiling and inspection of
the rifle. Complete disassembly is required for cleaning the rifle if
it is heavily soiled and after it has been exposed to the rain or snow,
or when the rifle is to be newly lubricated and repaired.
The frequent disassembly of the sniper rifle is harmful to the
weapon, as it tends to increase the wear of its parts and mechanisms.
When disassembling and assembling the sniper rifle do not apply an
extra effort and sharp blows.
When assembling the sniper rifle, check the numbers on its parts;
the number stamped on the receiver should correspond to the numbers
available on all its parts.
2.6.2. For partial disassembly of the sniper rifle, adhere to the
following procedure:
a. Detach the magazine. Take the magazine with the hand, press the
latch, move the bottom part of the magazine forward and detach it.
Then make sure that there is no cartridge in the cartridge chamber,
for which purpose lower the safety lock, retract the reloading handle
of the bolt support, inspect the cartridge chamber and release the
reloading handle.
b. Detach the optical sight. Raise the handle of the clamping screw
and turn it towards the eye shield as far as it will go; shift the
sight backward and detach it from the receiver.
c. Detach the cheek plate. Turn the fastener of the cheek plate lock
downward, remove the loop from the hook of the clip and detach the
cheek plate.
d. Detach the receiver cover together with the retracting mechanism.
Turn the axle pin of the receiver cover backward so as to engage it
with the axle pin retainer; raise the rear part of the receiver cover
and detach the receiver cover together with the retracting mechanism.
e. Detach the bolt support and the bolt. Pull back the bolt support
as far as it will go, raise it and detach it from the receiver.
f. Detach the bolt from the bolt support. Pull the bolt backward,
turn it so that its guiding lug comes out of the shaped recess of the
bolt support and move the bolt forward.
