DShK Machine Gun Manual
Degtyarev and fined with the drum dahk feed mechanism designed by G. The mashine gun was mounted on the general-purpose mount designed by L. Kolesnikov and boasting removable wheels and a folding tripod.
Norov significantly upgraded the heavy machine gun at the end of the Great Patriotic War. First and foremost, the drum feed mechanism was replaced with a shuttle-type one.
In addition to that production effectiveness was increased, attachment of the barrel was modified, and a number of measures, aimed at extending the service life of the barrel were taken. The reliability of the machine gun was increased as well. The fast upgraded machine guns were manufactured at a plant in Saratov in February The machine gun was fielded under the designation of The machine gun is gas-operated.
The closed gas cylinder is secured under the barrel and fitted with a gas regulator with three holes. The entire length of the barrel features lateral ribs for better cooling. The muzzle is equipped with manuaal active muzzle brake. The breech is locked by projecting bolt lugs.

The DShK barrel was equipped with a active type muzzle brake, later on replaced with an active flat brake DShK machine guns were also fatted with such muzzle brakes, which were the primary option for lank-mounted models. The bolt carrier assembly is the major component.
The front end of the bolt carrier assembly mounts the gas piston, while its rear end carries the firing pin. When the bolt approaches the breech, the bolt stops, while the bolt carrier assembly keeps on moving forward. As the firing pin, which is dsh to the bolt carrier assembly, drives forward, the projecting bolt lugs are cammed out by shoulders on the firing pin and engage in recesses in the side walls of the receiver.
The recesses cut into the top surface of the bolt carrier assembly, force the Socking lugs into the sides of the bolt, as the bolt carrier assembly goes back. The empty case comes out on the bolt face and is ejected through the manuao of the receiver, with the help of a spring-loaded pivoting cartridge ejector, mounted on top of the bolt.
The mainspring is wound around the gas piston and protected by a tubular casing. The back-plate is fitted with two spring recoil buffers, designed lo reduce the shock, caused by the bolt carrier assembly and the bolt in the extreme rear point.
In addition to that, the recoil buffers help the bolt carrier assembly and the bolt recover, thus, increasing the rate of fire.

The small cocking handle, mounted on the right side dsk, is fixed to the bolt carrier assembly. The cocking handle is linked to the cocking mechanism of the gun mount, but the gunner can use the cocking handle directly, for instance, by [inserting a cartridge rim into it. The machine gun fires from the rear sear from the open bolt.
The trigger assembly provides for automatic fire only. The trigger fshk hinged to the back-plate of the machine gun. The trigger assembly is accommodated inside a separate housing and nanual with a manual safety, which blocks the trigger when the safety lever is in sis forward position and prevents a spontaneous release of the sear.
The trigger assembly is operated by the mainspring. After locking the breech the bolt carrier assembly continues its forward motion, and the firing pin hits the striker, mounted in the bolt. The sequence of camming out locking lugs and hitting the striker rules out a discharge until the breech is completely locked.
In order to prevent the immediate recoil of the bolt carrier assembly after it reaches its extreme forward point there is a delay mechanism, which comprises two springs, a plunger, and a roller. Ammunition feed is from a metal-link belt from the left. The ammunition belt consists of disintegrating open links, manhal into a metal belt box, attached to the machine gun mount. The belt box cover acts as a bell feed tray.
The DShK drum feed mechanism was operated by the manul stud.
At the same time another pawl prevents counter rotation. The drum rotation draws the belt into the gun. A cartridge is removed from a belt link to the left side. On the DShKM machine gun a shuttle-type feed is mounted on top of the receiver The feed slide with pawls is operated by the rotating feed lever, which in its turn is driven by the operating stud just like on the DShK machine gun.
The machine gun can readily be adapted for feed from either side, by reversing the feed slide lever. There are several versions of the The cartridge case is rimless, which allows rounds to be fed directly from the belt. Ground targets were engaged with the help of a vertical leaf with U backsight mounted on top of the recerver. When the sight is upright the elevating screw is at the top.
There is a windage knob at the base of the sight. The sight is graduated for every m up to m 35 graduation lines. When machine gun fired at a ground target deviation at a range of m totalled mm.
The DShKM machine gun is equipped with a collimator anti-aircraft sight, which enables the gunner to train the gun on a high-speed target and see the crosshairs as clear as the target.
The optical system of the sight generated an image of the target with a projected target reticule for leading fire and azimuth scales.
