The order of incomplete disassembly of the grenade launcher.

– dismantling and assembling the grenade launcher on a table or clean bedding

· Put the parts and mechanisms in the order of disassembly, handle them carefully.

I. Remove covers (first from the breech, and then from the muzzle of the grenade launcher).

2. Separate the trigger mechanism .

Pushing out the checks shock-

trigger

3. Separate the firing mechanism.

  • holding the barrel with your left hand, unscrew the nipple with your right hand using a screwdriver wrench

and remove the striker, striker spring and support sleeve from the base of the striker mechanism.

Unscrewing the nipple of the firing mechanism

4. Separate the trigger housing cover

  • take the trigger mechanism in the left hand with the right hand, using the screwdriver wrench, unscrew the four screws and remove the cover of the trigger housing.

Assembly order of the grenade launcher

after incomplete disassembly ,

1. Attach the trigger housing cover: Replace the trigger housing cover and screw in the four screws.

2. Attach the firing mechanism :

put the spring on the striker, insert the support sleeve and the striker with the spring into the base of the striker mechanism and screw the nipple with a screwdriver until it stops into the support sleeve.

3. Attach the trigger mechanism : insert the protrusion of the base of the firing mechanism into the cutout on the body of the trigger mechanism, press the trigger mechanism against the barrel and insert the pin into the hole on the left side.

4. Check the correct assembly of the grenade launcher:

put the trigger on the cocking, when you press the trigger, the trigger should vigorously hit the striker.

5. Put on covers (first on the muzzle, and then on the breech).

General device.

The grenade launcher consists of :

1. Barrel with a mechanical (open) sight.

2. Trigger mechanism with a fuse.

3. Striking mechanism.

4. Optical sight.

The grenade launcher kit includes:

Spare parts : 2- strikers; 2- striker springs; 2-support bushings; 1-nipple (in the bag pocket for two grenades)

Tool ; 1 wrench; 2 drift; 3 devices for assembling and disassembling USM (in the pocket of the bag for two grenades)

1 Key screwdriver

2Punch

3Adaptation USM

4 punch groove

5 slot for screwdriver

P Accessories : I. cleaning and lubricating rod for grenade launcher (in a bag for two grenades)

2. stem with a washer to remove the remnants of the powder charge from the bore of the barrel. (in a bag for two grenades).

3. belt with covers (the belt must be adjusted so that the cover from the muzzle is removed only after removing the cover from the breech of the grenade launcher)

4.shoulder strap

5. A bag for storing and carrying three grenades with powder charges.

6. A bag for storing and carrying two grenades with powder charges.

In addition, for every 9 grenade launchers, a group kit of spare parts is attached, including a device for checking sighting devices, a device for assembling and disassembling the USM and spare parts for the grenade launcher.

2 – nests for a pencil case with a powder charge;

Z – socket for a ramrod;

4-pocket for spare parts and tools

When fired from a grenade launcher, a powder charge is ignited by the impact of the striker on the primer-igniter of the grenade. The gases formed from the combustion of a powder charge give the grenade a rotational motion and throw it out of the barrel at a speed of 120-140 m / s.

After the grenade leaves the barrel, the stabilizer feathers open, the fuse is cocked at a distance that ensures the safety of the shooter and the ignition of the powder charge of the jet engine. When the powder charge of a jet engine burns, due to the outflow of powder gases through the nozzle holes, a reactive force is formed and the speed of the grenade increases, reaching 300 m / s at the end of the complete combustion of the charge.

When a grenade meets an obstacle, the piezoelectric element of the fuse is compressed, as a result of which an electric current is generated, under the influence of which the electric detonator of the fuse explodes, and then the explosive charge of the grenade. When a grenade explodes, a cumulative jet is formed that pierces armor, strikes manpower, and destroys weapons and equipment.

When fired, the grenade launcher has no recoil. This is ensured by the outflow of powder gases back through the nozzle and the socket of the barrel nozzle. The resulting reactive force directed forward balances the recoil force,

2. Appointment and arrangement of parts and mechanisms of the grenade launcher and shots for it.

I. Barrel – for directing the flight of a grenade and removing powder gases when fired.

Consists of: a pipe and a branch pipe.

a). The pipe in the breech has a widening that forms a charging chamber.
