7.62 Sniper Rifle - Pistol with wooden guard/gas tube and stock with bone used before replacement for black forged stock.

It was developed in 1958-1963 and was chosen as the winner of a competition involving three teams of competing designers, led by Sergei Simonov (model rejected in April 1960), Aleksandr Konstantinov, and Yevgy Dragunov. Extreme gun tests conducted in a wide range of environmental conditions (Konstantinov's competing prototype 2B-W-10 was light and cheap but inaccurately tested, durable and reliable) caused the Dragunov's proposal is accepted into service in July 1963.

The first pre-production batch consisting of 200 rifles was assembled for testing purposes, and from 1964 serial production was carried out by Izhmash, which was later renamed Kalashnikov Concern .
Since then, the SVD has become a standard instrument of support for a number of countries, including those of the former Warsaw Pact. China produced a copy of the SVD using recovered samples taken during the Sino-Vietnamese War as the Type 79 and 85.
Iran also produced a clone, the Nakhjir 3, which was a direct copy of the Chinese Type 79.
The SVD has a number of cosmetic similarities to the AK family of rifles but these similarities are for manual calibration purposes. This has sometimes led to SVD being misdiagnosed as a variant of AK, and vice versa.

The barrel breech is locked with a rotating bolt (left rotation) and uses three locking lugs to capture the corresponding locking points on the expansion barrel. The rifle has a hammer cocking mechanism and a hand lever safety selector. In addition to the disconnecting trigger, the fire control mechanism has a second disconnector that does not allow the hammer to fall until the bolt is closed, similar to the control in the selective fire device. However, the SVD was designed for automatic fire only. The firing pin in the SVD is not stored, i.e. "free-floating", so it is possible for acidtal release to occur as the bolt pushes the unfired cartridge into the chamber, if any an obstruction in the pivot groove from poor storage or excessive cold.
The gun is powered by a short stroke gas system with a two position gas regulator. The gas regulator can be set with the help of the end of the cartridge. Position #1 leaves the gas outlet port open, while position #2 closes the gas outlet port and directs additional gas to the piston, increasing the rate of gas piston system recovery and is used to solve reliability issues from piston fouling. port/gas movement, extreme cold, high altitude, or using weak ammunition.
The gun is fed from a curved box magazine with a capacity of 10 rounds and the cartridges are loaded twice in an interlocking zigzag pattern. After removing the last cartridge from the magazine, the bolt carrier and bolt are held in the bolt grip which is released by pulling the cocking handle back.
The barrel profile is relatively thin to save weight. Its piercing is chrome-plated for greater corrosion resistance and features four grooves on the right. Originally, the twist rate was 320 mm (1:12.6 in), as it was designed for use with heavy civilian ammunition. In 1975 the twist ratio was increased to the standard 240 mm (1:9.4 in), which reduced the accuracy of the 7N1 sniper cartridge by 19% but allowed the use of the standard "light" steel LPS Gzh (57-N -323S). ), and its variants (incdiary, track, armor piercing) with acceptable accuracy.

The front of the barrel has a front sight assembly and a bayonet lug. The mouthpiece is equipped with a sealant that remains attached for a long time.
To pass factory inspection, these guns must produce no more than 0.7 MOA deviation from the median from the expected point of impact in three groups of 10 shots using the 7N1 (about 3 MOA).
To be able to achieve the required accuracy of the SVD, new "sniper" weapons, designated 7N1, were developed by V. M. Sabelnikov, P. P. Sazonov and V. M. Dvorianinov in 1966 to meet new standards. The 7N1 sniper cartridges must produce no more than 1.24 MOA vertical spread with a 240 mm twist rate barrel and no more than 1.04 MOA vertical spread with a 320 twist rate barrel mm in a 5-shot group. The accuracy requirements required for the SVD and 7N1 are the same as the American M24 Sniper Weapon System with M118SB cartridges (1.18 MOA overshoot) and the M110 Semi-Automatic Sniper System with M118LR ammunition (1.27 MOA spread excessively).
7N1 differs from the standard LPS Gzh cartridge (57-N-323S) in the use of an improved propellant and a modified propellant that contains a hollow inside the jacket at the tip improved terminal ballistics and a bimetal lead and a light steel core. With standard 57-N-323S cartridges, SVD accuracy is reduced to 2.21 MOA due to excessive vertical dispersion. These armors were later replaced by the 7N14 in 1999, which replaced mild steel with hardened steel in response to the development of children's armor.

Unique PSO-1 reticle. Rangefinder is in the lower left, chevrons for distances beyond 1,000 m (1,094 yd) are in the center, and air stage markings to the left and right of the reticle . The reticle is illuminated by a small battery powered flashlight.
The rifle has an adjustable steel rear sight, graduated from 100 to 1,200 m (109 to 1,312 yd) in increments of 100 m (109 yd). Metal sights can be used with or without a standard spotting scope. This is possible because the scope mount does not block the space between the front and rear sight.
The SVD was originally issued with a visible PSO-1 mount (now PSO-1M2) on the Warsaw Pact rail on the left side of the receiver.
The field of view of the PSO-1 must be placed at a range greater than 1,300 m (1,422 yd); effective range in combat conditions is reported to be 600 to 1,300 m (656 to 1,422 yd), depending on the nature of the target (target point or area), the quality of the ammunition and the ability of the -shooter.

The military group releases other telescope sights with different magnification levels and reticles are available for the SVD. Rifles designated SVDN are equipped with night vision, such as NSP-3, NSPU, PGN-1, NSPUM or the Polish passive PCS-5. Rifles designated SVDN-1 may use the NSPU-3 passive night sight (1PN51)
Non-military commercial mounts attached to the Warsaw Pact rail may allow the use of a Picatinny mounted sight rail.
The original SVD had a double birch plywood handguard/gas tube cover and a skeletonized thumbhole stock fitted with a detachable cheek rest; the latter is removed using metal tools. Since the 80s, the wooden parts have been replaced by parts made of black polymer - the handguard and the gas tube cap are visually similar, while the stock bore of -big has a different shape.
A number of accessories are issued with the pistol, including a blade-type bayonet (the cut-off AKM or AK-74 spear point bayonet), four extra magazines, a leather or nylon sling, a pouch magazine, cleaning kit and and accessory / repair. telescopic sight kit. Also included is a cold weather battery case with a "shirt clip", which has a permanently attached cable [about 24" long] ding and another battery cover with an extension to press against the internal contact instead of the battery to finish. case of the external battery on the clothing of the shooters close to the body keeps it from freezing, using the clip ensures that it stays in place.
