1 DESCRIPTION AND OPERATION OF THE VITYAZ AND VITYAZ-SN SUB-GUNS
1.1 Purpose of submachine guns
1.1.1 9-mm submachine guns "Vityaz" and "Vityaz-SN" are
powerful individual weapons and are designed to destroy live targets and unarmored vehicles.
1.1.2 Full name of submachine guns:
– 9-mm submachine gun PP-19-01, execution 10 Vityaz PP-19- 01.Sat-10. The appearance of the submachine gun in accordance with Figure A.1.
– 9-mm submachine gun PP-19-01, execution 20 Vityaz-SN PP-19- 01.Sat-20. The appearance of the submachine gun in accordance with Figure A.2.
– 9-mm submachine gun PP-19-01, execution 20 Vityaz-SN PP-19- 01.Sat-20-01. The appearance of the submachine gun in accordance with Figure A.3.
1.1.3 For firing from submachine guns, 9-mm pistol cartridges 9x19 PRS are used.
The design of submachine guns provides for the possibility of using 9-mm pistol cartridges with a bullet of increased penetration for firing. (9x19) index 7Н21. When using 7N21 cartridges for firing, remember, that the range settings on the sights of submachine guns correspond to the 9x19 PRS cartridge. therefore, if the submachine gun is brought to normal combat with 9x19 PRS cartridges, due to the higher initial speed of the bullet for the 7N21 cartridge, the point of impact will be higher, than when firing cartridges 9x19 PRS.
In the absence of cartridges 9x19 PRS and 7N21 for firing pistols- machine guns can be used cartridges 9x19 "Parabellum" of domestic and foreign production.
1.1.4 Submachine guns are fired automatically or single shot. Automatic firing is carried out short (to 5 shots) and long (to 10 shots) queues or continuous queue.

In the PP-19-01.Sb-20 version, the submachine gun is equipped with a Picatinny rail for mounting collimator and optical sights, located on the cover of the receiver. In the version of PP-19- 01.Sb-20-01 submachine gun is equipped with a standard rail for mounting optical and collimator sights, located on the left side of the receiver.
1.4.3 The work of automatic submachine guns
The work of automation of submachine guns is based on the principle of using the recoil energy of a free shutter.
When fired, powder gases press on the bottom of the sleeve. The shutter moves back together with the sleeve, but, since its mass is much greater than the mass of the bullet, the shift of the shutter by the time the bullet leaves the bore is insignificant and the destruction of the sleeve under the pressure of the powder gases does not occur. After the bullet leaves the bore, the shutter moves back by inertia.
When moving back, the ejector bolt removes the cartridge case from the chamber and, using a reflector, ejects it from the receiver. At the same time, the bolt compresses the return mechanism spring and cocks the hammer.. The trigger stands on the self-timer sear and is held in the cocked position..
The shutter returns to the forward position under the action of the return mechanism., at the same time, he sends a cartridge from the magazine to the chamber and closes the bore. At the end of the movement to the forward position, the shutter turns the self-timer and removes the self-timer sear from under the cocking of the trigger..

PP-19-01 RE
If the translator is set to automatic fire, then the shooting will continue until then, while the trigger is pulled and there are cartridges in the magazine.
If the translator is set to single fire, then the trigger, after being released from the self-timer sear, will cock the single-shot sear. To fire the next shot, you need to release the trigger and press it again.

The position of the parts and mechanisms of the submachine gun before loading
The shutter under the action of the return mechanism is in the extreme
forward position. The return spring has the least preload. The self-timer lever is turned forward by the action of the self-timer tab and
down. 12
PP-19-01 RE
The trigger is pulled down and rests on the shutter. Drummer under the action of the trigger moved forward. The mainspring is at its lowest preload, with her noose she presses the trigger to the bolt, and with curved ends presses the rectangular protrusions of the trigger to the bottom of the receiver, while the “tail” of the trigger is in the forward position.
The translator is in the uppermost position and closes the stepped cutout in the receiver cover (the translator is on safety); the translator sector overlaps the stepped protrusion of the single-shot sear and is located above the right rectangular protrusion of the trigger (locks the trigger).
1.5.4 The operation of parts and mechanisms of the submachine gun during loading To load the submachine gun, you must attach an equipped magazine, put the translator on automatic or single fire (position «AV» or «OD»), pull the bolt by the handle back to the stop and release sharply. If there is no immediate opening of fire, then you need to put the submachine gun on the fuse.
Submachine gun loaded.
When setting the interpreter to automatic or single
shooting, a stepped cutout for the bolt handle in the receiver cover is released, the translator sector releases the rectangular ledge of the trigger and does not prevent it from turning.
When the bolt is pulled back, the barrel bore opens., return spring is compressed, the trigger under the action of the shutter rotates on the axis, mainspring is twisted, the cocking of the trigger jumps over the curly ledge of the trigger, and then the trigger is on the self-timer ledge, the self-timer lever is then rotated up and in the path of the shutter projection.
As soon as the bottom surface of the bolt passes the magazine, the feeder, under the action of the magazine spring, lifts the cartridges all the way into the bends of the magazine. When moving forward under the action of the return mechanism, the bolt pushes the upper cartridge out of the magazine, sends it into the chamber and closes the bore. When coming to the forward position, the ejector hook jumps into the annular groove of the sleeve, and the self-timer lever is rotated forward and down by the action of the shutter, removing the self-timer sear from under the self-timer cocking; the trigger under the action of the mainspring turns and becomes a combat platoon on the curly ledge of the trigger.
Cartridges in the store under the action of the feeder rise to the stop
upper cartridge in the bolt. 13
PP-19-01 RE
The translator put on the fuse closes the stepped cutout of the receiver cover and gets in the way of the movement of the bolt handle, preventing it from moving backwards; translator sector turns forward and becomes over the right rectangular ledge of the trigger (locks the trigger).
1.5.5 The work of parts and mechanisms of a submachine gun when firing
1.5.5.1 The work of parts and mechanisms of a submachine gun during automatic firing
To conduct automatic shooting, you must put the translator on automatic shooting "AB", if it was not delivered when loading, aim and pull the trigger.
When the interpreter is set to automatic firing, the interpreter sector releases the rectangular ledge of the trigger (unlocks the trigger), but overlaps the stepped protrusion of the single-shot sear. The trigger gets the ability to rotate around its axis, the single-shot sear is kept from turning by the interpreter sector.
When you press the tail of the trigger, its curly protrusion disengages from the cocking of the trigger. The trigger under the action of the mainspring rotates on its axis and vigorously strikes the drummer. The striker breaks the cartridge primer with a striker. The percussion composition of the primer ignites and ignites the powder charge through the seed holes in the bottom of the cartridge case.. It occurs shot.
The bullet under the action of powder gases moves forward along the bore, and the shutter, under the action of powder gases on the bottom of the sleeve, moves back together with the sleeve. After the bullet leaves the bore, the shutter moves back by inertia. When moving back, the bolt removes the cartridge case from the chamber and, using a reflector, ejects it from the receiver. At the same time, the bolt compresses the return mechanism and cocks the hammer.. The trigger stands on the self-timer sear and is held on it until the shutter arrives in the front position. The shutter reaches the rear position and moves forward under the action of the return mechanism.. When moving forward, the bolt sends the upper cartridge from the magazine into the chamber and closes the bore. At the end of the forward stroke, the shutter protrusion presses the self-timer lever and releases the self-timer sear from- under platoon is afraid of self-timer. The trigger under the action of the mainspring turns and strikes the drummer. It occurs shot. The work of parts and mechanisms of the submachine gun is repeated. Automatic firing will continue until, while the trigger is pressed and
store has ammo. 14
PP-19-01 RE
Release the trigger to stop firing.. In this case, the trigger turns under the action of the mainspring and its curly protrusion gets in the way of the cocking of the trigger, the trigger becomes on a combat platoon. Shooting stops, but the submachine gun remains loaded, ready for further automatic firing.
1.5.5.2 The work of parts and mechanisms of a submachine gun during single firing
To fire a single shot, it is necessary to put the translator on single shooting "OD", aim and pull the trigger.
When the translator is placed in the position for single shooting, the translator sector releases the rectangular trigger protrusion (unlocks the trigger) and stepped ledge whispered single firing.
When you press the "tail" of the trigger, its curly protrusion disengages from the cocking of the trigger. The trigger under the action of the mainspring rotates on its axis and vigorously strikes the drummer. It occurs shot. After the first shot, parts and mechanisms do the same work., as with automatic shooting, but the next shot does not occur, since, together with the trigger, the single-shot sear rotates and its hook gets in the way of the movement of the cocking of the trigger. therefore, after the shutter rotates the self-timer and releases the trigger, the cocking of the trigger jumps behind the sear of single firing and the trigger stops in the rear position.
In order to fire the next shot, you need to release the trigger and pull it again. When the trigger is released, under the action of the mainspring, it rotates along with the single-shot sear, the single firing sear disengages from the cocking of the trigger and releases the trigger. The trigger under the action of the mainspring turns and stands on the curly ledge of the trigger. When the trigger is pressed, its curly protrusion disengages from the cocking of the trigger and the work of parts and mechanisms is repeated. Another shot is fired.

2.4 Checking the accuracy and accuracy of firing a submachine gun and bringing it to normal combat
2.4.1 General provisions
Submachine gun, subdivisional, must always be brought to normal combat.
Checking the accuracy and accuracy of fire of a submachine gun is carried out when it enters the unit, after repair and replacement of parts, which can affect the accuracy and accuracy of fire, when abnormal bullet deviations are detected during firing.
Checking the accuracy and accuracy of firing a submachine gun and bringing it to normal combat are carried out at the shooting range in calm weather, in an enclosed shooting range or on a wind-sheltered section of the shooting range and under normal lighting by the shooter, behind which a submachine gun is attached. Shooting distance 50 m. On the Vityaz submachine gun, the rear sight must be set to position "1", on the submachine gun "Vityaz-SN" the collar of the aiming bar must be set to division "5". Shooting position - lying down.
Shooting is carried out at a test target, mounted on a white shield not less than 1 m and a width of at least 0,5 m. The test target is a black circle with a diameter 15 cm or black rectangle width 25 cm and height 35 cm. When shooting at a test target, the aiming point is the middle of the lower edge of the target., it should be approximately at the level of the shooter's eyes. The position of the control point is the same as the aiming point.
Checking the accuracy and accuracy of firing a submachine gun and bringing it to normal combat is carried out by firing single shots (4 chuck).
2.4.2 Checking the accuracy and accuracy of fire
To check the accuracy and accuracy of shooting, the shooter fires four shots, carefully and uniformly aiming at the middle of the lower edge of the test target.
22
PP-19-01 RE
At the end of the shooting, the target is inspected and the accuracy and accuracy of shooting is determined by the location of the holes. (midpoint position).
Accuracy of fire is recognized as normal, if the bullet dispersion diameter – "P", determined in accordance with Figure 30a) as the distance between the two most distant holes from each other, less than 40 cm. If the location of the holes does not meet this requirement, then the shooting is repeated. allowed, in case of repeated unsatisfactory result in accuracy of fire, involve the most experienced shooter of the unit to check the accuracy of fire, having consistently better test firing results from this weapon model. If the result of checking the accuracy of fire is unsatisfactory, the submachine gun is sent to a repair shop to identify and eliminate the causes of bullet dispersion.
If the accuracy of fire is considered normal, then the shooting accuracy is determined - the average point of impact (STP) and its position relative to the aiming point (TP).
To determine the STP for four holes, you need, in accordance with Figure 30b):
– connect holes in pairs;
– connect the midpoints of both lines and divide the resulting line in half;
– the division point will be the STP.
With normal firing accuracy of a submachine gun, the STP must coincide with the TP or deviate from it in any direction by no more than 5 cm.
Submachine gun, for which the deviation of STP from TP exceeds 5 cm, brought to normal combat.
2.4.3 Bringing the submachine gun to normal combat
If, when firing single shots, the STP deviated from the TP in any direction by more than 5 cm, then, accordingly, the position of the front sight is changed; if STP is below TP, the fly must be screwed, if higher - unscrew; if the STP is to the left of the TP, move the base of the fly to the left, if to the right - to the right.
The amount of movement of the STP relative to the TP, depending on the movement of the front sight, is presented in the table 2.

3 MAINTENANCE
3.1 Overview
To keep the submachine gun in constant readiness for immediate use, the following types of inspection and maintenance should be systematically carried out:
– control inspection (KO);
– ongoing maintenance (TeO);
– seasonal service (WITH).
3.2 Control inspection of the submachine gun
3.2.1 The control inspection of the submachine gun is carried out to assess
serviceability of the submachine gun, his state of purity, smears, carried out by visual inspection and function test.
Control inspection is carried out as an independent type of maintenance (before performing official tasks), and as part of the current service (during cleaning and disassembly).
3.2.2 The procedure for the control inspection before performing official tasks
When inspecting, make sure that all parts of the gun are present.- machine gun and check, Is there any rust on the outer parts?, mud, dents, scratch, language, chips and other damage, that can cause malfunction of the mechanisms; Besides, check the condition of the lubricant on parts visible without disassembly, make sure, that there are no foreign objects in the bore; check the correct operation of the mechanisms.
The submachine gun magazine must fit into the neck of the receiver without rubbing and be securely fixed with the magazine latch. To check the reliability of fixation, attach the magazine and, without pressing the magazine latch, try to separate it by force of the hand.
When checking the correct operation of parts and mechanisms, disconnect the magazine, remove the submachine gun from the fuse and put the translator on automatic shooting "AB", take the shutter by the handle back to failure and release it. In this case, the shutter should vigorously return to the forward position.. Pull the bolt back by the handle again, pull the trigger and, while holding the shutter by the handle, slowly release it. When the shutter approaches the extreme forward position, a click should be heard - the hammer strikes the drummer. Put the translator on single shooting "OD", pull the trigger, pull the bolt by the handle back to failure and, without releasing the trigger, release the shutter. Release the trigger, at the same time, a click should be heard - the trigger,
