Incomplete disassembly and reassembly after incomplete disassembly of the 7.62 mm Dragunov sniper rifle (SVD)

Disassembling a sniper rifle can be incomplete or complete:

Partial - for cleaning, lubricating and inspecting the rifle

Full - for cleaning when the rifle is heavily soiled, after being in the rain or snow, when switching to a new lubricant and during repairs. Frequent disassembly of the rifle is not allowed, as it accelerates the wear of parts and mechanisms.

Disassembling and assembling the rifle should be done on a table or clean mat, parts and mechanisms should be placed in the order of disassembly, handle them carefully, do not place one part on top of another, and do not use excessive force or sharp blows. When assembling a rifle, compare the numbers on its parts: the number on the receiver must correspond to the numbers on the bolt frame, bolt, trigger mechanism, receiver cover, optical sight and other parts of the rifle.

Training in disassembly and assembly on combat rifles is permitted only in exceptional cases, subject to special care in handling parts and mechanisms.

The procedure for incomplete disassembly of a sniper rifle.

1) Separate the store. Hold the magazine with your right hand, pressing the latch with your thumb, move the bottom of the magazine forward and separate it. After this, check to see if there is a cartridge in the chamber, to do this, lower the safety down, pull the charging handle back, inspect the chamber and release the handle.

2) Separate the optical sight. Lift the handle of the clamping screw and turn it towards the eyecup until it stops, move the sight back and separate it from the receiver.

3) Separate the butt cheek.

4) Separate the receiver cover with the return mechanism. Turn the receiver cover lock back until it is locked into place; lift up the rear part of the receiver cover and separate the cover with the return mechanism.

5) Separate the bolt carrier with the bolt. Pull the bolt carrier back as far as it will go, lift it and separate it from the receiver

6) Separate the bolt from the bolt frame. Pull the shutter back; turn it so that the leading protrusion of the bolt comes out of the figured cutout of the bolt frame, and move the bolt forward

7) Separate the shock and trigger mechanism. Turn the safety up to a vertical position, move it to the right and separate it from the receiver, holding the trigger guard and moving it downward to separate the trigger mechanism from the receiver.

Separate the barrel linings. Press the contactor of the upper thrust ring against the gas tube until the bend of the contactor comes out of the cutout of the ring and turn the contactor to the right until it stops; move the moving part of the upper thrust ring forward, pressing the barrel lining down and moving it to the side, to separate it from the barrel. If it is difficult to separate the barrel linings, insert the cutout of the pencil case key into the window of the lining and move downwards and to the side to separate the barrel linings

9) Separate the gas piston and pusher with spring. Pull the pusher back, remove its front end from the piston socket and separate the piston from the gas tube, insert the front end of the pusher into the gas tube, press the pusher spring until it leaves the channel of the aiming block and separate the pusher with the spring, and then separate the spring from the pusher.

The procedure for assembling a sniper rifle after partial disassembly.

1) Attach the gas piston and pusher with spring. Place the spring on the rear end of the pusher; insert the front end of the pusher into the gas tube, tighten the spring and insert the rear end of the pusher with the spring into the channel of the aiming block; pull the pusher back and move its front end out of the gas tube to the side; insert the gas piston into the gas tube and the front end of the pusher into the piston socket.

2) Attach the barrel linings. Insert the rear (widened) end of the right (left) barrel lining into the lower thrust ring with the cutout of the lining towards the sight and, pressing the lining down, attach it to the barrel; push the moving part of the upper thrust ring onto the tips of the linings and turn the closure of the upper thrust ring towards the gas tube until its bend enters the cutout on the ring.

3) Attach the shock-trigger mechanism. Place the cutouts of the trigger mechanism housing behind the axis of the receiver jumper and press the trigger mechanism to the receiver; insert the fuse axis into the hole in the receiver; Turn the fuse to a vertical position, press it tightly to the receiver and turn down until the protrusion of the shield enters the lower locking recess of the receiver.

4) Attach the bolt to the bolt carrier. Insert the bolt with the cylindrical part into the channel of the bolt frame; turn the bolt so that its leading protrusion fits into the figured cutout of the bolt frame, and push the bolt forward as far as it will go.

5) Attach the bolt carrier to the bolt. While holding the bolt in the forward position, insert the guide protrusions of the bolt frame into the cutouts of the receiver bends, press the bolt frame against the receiver with a slight force and push it forward.

6) Attach the receiver cover with the return mechanism. Insert the return mechanism into the bolt frame channel; compressing the return springs, insert the protrusions on the front end of the cover into the cutouts on the lower thrust ring; press the rear end of the cover until it is completely adjacent to the receiver; Turn the receiver cover lock forward until it engages the lock.

7) Attach the butt cheek. Place the cheekpiece on the top of the butt with the clasp to the right opposite the cutout for it; put the loop on the hook of the clip and turn the clasp up.

Attach the optical sight. Align the grooves on the sight bracket with the protrusions on the left wall of the receiver; push the sight forward as far as it will go and turn the clamping screw handle toward the lens until its bend fits into the cutout on the bracket.

9) Attach a magazine. Insert the magazine hook into the receiver window and turn the magazine towards you so that the latch jumps over the magazine support ledge.

The procedure for completely disassembling a sniper rifle

1. do partial disassembly
2. disassemble the store . Having sunk the protrusion of the locking bar into the hole on the magazine cover, slide the cover forward; holding the locking bar, remove the cover from the housing; gradually releasing the spring, remove it together with the locking bar from the magazine body; separate the feeder
3. disassemble the return mechanism. Remove the front return spring from the guide bushing; compress the rear return spring and, holding the guide rod, move it downwards and towards you from the earring hole; separate the rear recoil spring and guide rod from the guide bushing
4. disassemble the shutter. Using a punch, push out the firing pin and remove the firing pin from the bolt hole; remove the ejector with the spring in the same way
5. disassemble the trigger mechanism. Press the self-timer lever and disconnect the self-timer sear from the trigger, holding the trigger, press the trigger and smoothly release the hammer; remove the ends of the trigger spring from under the bends of the trigger mechanism housing; using a screwdriver, align the protrusions of the axes of the trigger, sear and self-timer with the cutouts for them on the right wall of the trigger mechanism housing: by pushing out the axes of the trigger, sear and self-timer, separate these parts; by pushing out the hammer axis, separate the hammer from the mainspring, and then remove the mainspring
6. separate the gas tube from the gas regulator. Having turned the regulator until the cutout on its front end aligns with the latch of the gas pipe, press the latch and, using a pencil case, unscrew the gas pipe and remove the regulator from it

The procedure for assembling a sniper rifle after complete disassembly

• connect the gas pipe with the gas regulator. Having placed the regulator on the gas tube, press the gas tube latch and screw the gas tube using a pencil case key until the cutout on the end of the tube matches the latch; Having pressed the latch into the cutout of the tube, set the regulator to the required division
• assemble the firing mechanism. Insert the trigger with its spring into the housing, insert the axle, align its protrusion with the cutout on the right wall of the case and turn the axle using a screwdriver. Place the mainspring on the hammer pins and insert the hammer into the housing. Insert the sear into the body so that its tail goes behind the loop of the long end of the mainspring; insert axle; align its protrusion with the cutout on the right wall of the case and turn the axis using a screwdriver. Insert the self-timer into the body so that its tail goes behind the loop of the short end of the mainspring; insert the axle, aligning its protrusion with the cutout on the right wall of the case and turn the axle using a screwdriver; insert the trigger axle and place the ends of the trigger spring on the bends of the body
• assemble the shutter. Having inserted the ejector with the spring into the bolt socket, press the ejector and insert the ejector axis, inserting the firing pin into the bolt hole, from the side of the leading protrusion, insert the firing pin into the bolt hole and push it to the end
• assemble the return mechanism. Having inserted the guide rod into the guide sleeve from the side of the large diameter hole (flat side forward), put the return spring on the guide sleeve from the side of the rod and compress it so that the end of the guide rod with the flats comes out from under the spring; holding the guide rod in this position, insert it together with the spring and bushing into the lower hole of the earring, and then push the rod along the edges of the flats into the upper hole; release the spring - its end should enter the cup of the earring. Place the second return spring onto the guide bushing
• assemble a store. Having inserted the feeder and the spring into the magazine body, compress the spring until the locking bar enters the body and, holding it in this position, put the magazine cover on the body so that the protrusion of the locking bar slides into the hole in the cover.
