d. in combat situation and prolonged tactical exercises, daily during lulls of the fight and during the intervals in the exercises;

e. if the sniper rifle is not in use, at least once a week.

2.7.2. Lubricate the sniper rifle after cleaning. Apply lubricant only to the well-cleaned and dry surfaces of the metal immediately after cleaning to avoid the adverse effect of moisture on the metal.

2.7.3. For cleaning and lubricating the rifle following materials are used:

• liquid rifle oil for cleaning the rifle and lubricating its parts and mechanism, when the ambient temperature is within +50 grad. C to -50 grad. C;

• rifle oil for lubricating the barrel bore, the rifle parts and mechanisms after their cleaning, the said oil is used when the ambient temperature exceeds +5 grad C;

• RCHS solution for scouring out the barrel bore and other parts affected by the powder gases.

Note - The RCHS solution is prepared in a subunit. The composition of the solution is as follows:

The RCHS solution is prepared in the amount required for scouring the weapon in the course of 24 hours. Small amount of the RCHS solution may be stored in tightly plugged glass vessels, away from heaters (in a dark place) for not more than 7 days. It is prohibited to fill the oilers with the BxN solution.

• waste or special paper KB-22 for wiping, scouring and lubricating the sniper rifle;

• tow free from boon only for scouring the barrel bore out.

2.7.4. To clean the sniper rifle, proceed as follows:

a. Prepare materials for cleaning and lubrication;

b. Disassemble the sniper rifle;

c. Prepare accessories for use during cleaning;

d. Scour out the barrel bore.

To scour out the barrel bore with liquid rifle oil put the tow on the scourer end and place the tow fibers along the scourer rod; soak the tow in liquid rifle oil. Insert the cleaning rod with the scourer and the tow into the barrel bore and secure the container cover on the flash eliminator. Holding the rifle with one hand smoothly move the scourer with the tow forward along the entire length of the barrel bore several times. Remove the cleaning rod, change the tow, soak it in liquid rifle oil and, adhering to the above procedure, scour the bore several times. Then thoroughly wipe the barrel bore with the clean dry tow, then with a clean waste cloth. To clean the barrel bore with the B*N solution, use the brush soaked in the solution; then wipe the barrel bore with tow. Proceed with cleaning the bore with the RCHS solution to completely remove the fouling. Having cleaned the rifled portion of the bore, clean the cartridge chamber.

e. Clean the gas chamber and the gas tube with the help of the cleaning rod or a wooden stick, wrapped with waste cloth around, washed with liquid rifle oil or the B*N solution; wipe the gas chamber and the gas tube dry after they have been cleaned; wipe the barrel bore with waste cloth once more and inspect it to see that no tow, waste cloth, rags or foreign matter are left therein;

f. Clean the receiver, the bolt and the gas piston with waste cloth soaked in liquid rifle oil or the B*N solution, then wipe them dry;

g. Wipe dry the rest metal parts with waste cloth;

h. Wipe the wooden parts with dry waste cloth.

2.7.5. Lubricate the sniper rifle as follows:

a. Lubricate the barrel bore with the help of the scourer and the waste cloth, soaked in lubricant; lubricate the cartridge chamber;

b. Lubricate all the remaining metal parts and mechanisms with oiled waste cloth;

c. Apply a thin layer of lubricant, as excessive lubrication tends to increase soiling of the rifle parts and may result in stoppages during firing;

d. Do not lubricate wooden parts.

2.7.6. Assemble the rifle and check the functioning of its parts and mechanisms.

2.7.7. Wipe the external surfaces of the optical sight with clean waste cloth. Remove the cap of the reticle illuminating set and wipe the cell, the body and the cap. Should the surfaces of the objective and eyepiece lenses be soiled, wipe them with cloth. Never wipe the lenses and glasses with a waste cloth, already used for wiping other parts of the sight. Do not lubricate them or touch with fingers. It is prohibited to strip the sight.
