    Work on the creation of anti-tank guns (MFI) in the USSR were begun in 1930. By the end of the 30s of the twentieth century Soviet designers MN Blum, SV Vladimirov, S. Korovin, NV Rukavishnikov and BG SHpitalna was created fifteen samples antitank guns. On the comparative tests in 1939 was recognized as the best 14,5 mm semi-automatic anti-tank rifle Rukavishnikova system, which in the same year it was decided to adopt the Red Army. However, in the same period in the circles of the Soviet military leadership prevailing misconception that in the coming war potential enemy tanks will have frontal armor thickness of 60-80 mm, and major efforts have been focused on the creation and production of relevant anti-artillery systems, and the mass production guns Rukavishnikova was folded almost before it began.

    C outbreak of hostilities in June 1941 in the Soviet Union, it became clear that the composition of armored and mechanized forces of Germany along with modern medium tanks T-3 and T-4, a large number of light-armored light T-1, T-2 and captured tanks Czech and French production, as well as armored vehicles and armored personnel carriers.

    outset of the Great Patriotic War was felt an acute shortage in mobile anti-tank weapons capable of acting directly in combat formations of infantry troops. In an extremely short time such a tool could be created only in the form of a classic anti-tank rifle.

    This task was set at the beginning of July 1941 by the famous Soviet small arms designer - VA Degtyarev and SG Simonov, which the Soviet government commissioned to design a cheap and quick in producing PTR.

    Both designers design and manufacture of prototypes took 22 days. Each designer presented two copies: VA Degtyarev - Shops semi-automatic, and SG Simonov - Shops and single-shot semi-automatic manual reload. Experienced shooting showed that autoloading PTR is quite efficient and suitable for use in the armed forces.

    In order to quickly establish and further reduce the cost of production, Degtyarev remade magazine-autoloading shotgun in the single-shot. After firing the shutter is automatically opened, increasing rate, accelerating the recovery of spent cartridges.

    August 29, 1941 GKO decree 14, 5-mm single-shot anti-tank gun model 1941 system Degtyareva PTRD was taken by the Red Army. The offer was accepted on arms and rifle Simonov - PTSD.

    as ammunition cartridges used in the MFR 14.5? 114 mm, before the war started just looking for anti-tank rifles. Usually used cartridges with armor-piercing incendiary bullets of two types - with steel core with a hot B-32 and metal core BS-41. Bullet BS-41 with a higher armor penetration was scarce and was used only for shooting at tanks. Both had a good incendiary effect.

    Antitank gun Degtyarev PTRD represents a single-shot design with manual loading, and automatic opening gate after the shot, which is achieved due to the use of energy efficiency.

    barrel of the weapon is locked rotary bolt, having in front of two radial lugs. Barrel of a gun has the ability to roll back against the metal lodge arms, clutching recoil spring buffer. At the same time during the rollback barrel bolt handle slides over the sloping ledge on the bed, so that the bolt is rotated such that it is unlocked. Under the influence of inertia and the residual pressure of powder gases is automatically opening the gate and eject spent cartridges. anti-tank gun Degtyarev PTRD

    Shutter consists of core speed and impact mechanism. The skeleton has a shutter: handle cup with a whisk (for placing the cap of the cartridge), channel (for the passage of the striker striker), tongue (for flat ejector), socket (for reflector and spring), two lugs (for locking the trunk), beveled cutout (drummer ago outlet when opening the shutter), the annular groove (which includes an annular projection coupling mechanism for coupling the shock to the core speed), and two holes (diverting powder gases in the event of a breakthrough inside the gate).

    firing mechanism consists of a drummer (having a protrusion with cocking), coupling (linking hammer mechanism with the gate), the mainspring (sending drummer to the front position), containment tube (limiting departure drummer ago), the coupling pin (striker keeps from disengaging from the drummer) and pin (smashing capsule). The trigger mechanism consists of a trigger, the trigger, sear and two springs (for the trigger and the sear).

    PTRD proceed as follows:

    Turn the bolt handle to the left (unlocked bore) Move the slide back to failure (slide catch abuts the rear plane left the gate lugs and keeps it in the receiver) Put the cartridge on the guide bevel top box receiver and send it to the chamber; runaway bolt forward (gate promotes cartridge in the chamber and the hammer cocked, stumbled on the trigger sear, the hammer stops, holding his cocked) Turn the knob to the right until the shutter failure (locked bore, action spring gets the most stress, ejection hook snaps in sharpening cap sleeve cap sleeve reflector is recessed in its nest). anti-tank gun Degtyarev PTRD

    After that shot, you only need to click on the tail of the trigger. Wherein:

    Trigger turns the trigger, causing the sear to fall and get out of cocking the hammer. Combat spring pushes the hammer pushes the clutch and forcefully sends forth a drummer with the striker, decomposing primer cartridge. Barrel from the receiver and trigger the shutter boxes and pulling back under the pressure of powder gases at the bottom of the sleeve than forcing compressed spring shock absorber. Bolt handle, reaching the brink of the tide curve of the outer tube, begins to slide on it and turn left. Lugs bolt out because of the support arms of the receiver and are against the longitudinal grooves. Shutter, moving by inertia ago, separated from the rear barrel shotgun and hook ejector sleeve extracts from the chamber. When the sleeve becomes against the lower window of the receiver, the reflector pushes her out of the toe of the ejector. Shutter stays in the rear position, bumping left lugs on the slide stop. Spring damper returns moving parts in the forward position. For setting trigger safety catch on the hook must pull the hammer back to failure and turn it to the right.  anti-tank gun Degtyarev PTRD

    trunk channel has eight rifling, winding up on the left to the right, the muzzle brake to reduce recoil. Located in the middle of the trunk handle for carrying weapons and a groove for mounting a bipod. In front of the barrel has a front sight base (which is planted on fly), and in the back - an arm of sight.

    The receiver is located on the left slide catch, and bottom - the trigger. Outside it has: the upper window (for insertion of the cartridge), the lower window (ejection port), with the projection area (for connection to the butt), cut-out (to go the bolt handle when locking and unlocking of the barrel). Inside the receiver is: channel for placing the shutter two longitudinal grooves and two support arms.

    butt attached to the receiver and consists of a shoulder rest (pillow) with the outer tube and trigger box with inner tube. In the outer tube is a spring shock absorber, and the left is a stop for cheeks gunner. Right there with the tide curve edge to open the gate after the shot. To cushion the outer tube and attached a wooden fence to keep the left hand while firing. In the trigger box with inner tube is the trigger. To the inner tube is attached for ease of firing the pistol grip. Shutter box has a butt pad to connect to the receiver, the hole for the studs (studs shutter box to the receiver) and trigger guard (protects against accidental operation of the trigger).

    sight consists of the bracket with the rear sight notch, and a spring. In earlier samples bracket has an opening through which moves up and down the pillar. In the lower position entirely consistent shooting distances up to 400 m, and the top - from 400 m to 1000 m in the same pillar later turns on an axis of 90 °, also having two positions for shooting at distances up to 400 m and from 400 m to 1000 m Fly pushed into the groove sight base and can move left and right when casting PTRD to normal battle.

    Affiliation PTRD: composite ramrod key, screwdriver, dvugorlovaya oiler and brush. Also on every gun has two canvas bags ammunition (20 rounds each), two canvas cover (at the breech and muzzle of the gun) and Form (test result of battle, the number of shots, delays and ways to address them).

    PTRD using Mass production

    PTRD was organized at the Kovrov plant. Mounting party was made by October 1941, but only in 1941 the troops were supplied guns 17688. Gun Degtyarev proved very technologically advanced. In 1942 he was made PTRD 184800, which allowed not only to meet the needs of troops, but also to create the year-end reserve antitank guns.

    Because of its simplicity and cheapness in the production PTRD produced in much larger quantities than PTSD (for years 1941-42 was issued about 60,000 anti-tank rifle Simonov). But already in 1943, production was curtailed rifles, as the rapid growth of the German tanks made reservations weapon caliber 14.5 mm ineffective. Nevertheless, anti-tank guns Degtyareva PTRD actively used until the end of the war - they were used against light armored vehicles, field fortifications, partially used in defense.

    Trophy PTRD used by the Germans under the designation PzB 783 (r). Gun supplied to the Polish Army and the Czechoslovak formation, as well as in Mongolia, China and the DPRK. After the Second World War PTRD applied during the conflict in Korea.
