SP-5 — the sniper cartridge, which was developed by other inventors, N. V. Zabelin and L. S. Dvoryaninov, was also adopted in 1987.

When creating the SP-5, the good old cartridge of 7.62 * 39 US-caliber (Haveless WITHspeed). Such cartridges were used in automatic machines. AKM with the device PBS-1. The bullet from this cartridge possessed a subsonic speed of 310 m / s, which, when using the muffler, made the firing of a submachine gun low-noise. At the same time, the bullet had a decent weight of 12.6 g and a design that provided effective destruction of enemy personnel at a distance of up to 400 meters. However, there was a drawback: low accuracy of fire. In the 1960s, the indicator was satisfactory, but in the 1980s, it was clearly not enough.

So, on the basis of the liner from this 7.62 * 39 mm cartridge, a sniper cartridge with a subsonic (300 m / s) speed of a bullet was developed, which received the working designation РГ037. It had a length of 46 mm, with a total mass of 16 g, a mass of a bullet of 10.6 g, and had good accuracy of fire. At a distance of 100 meters R50 = 4 cm, and 400 m – R50 = 16.5 cm

Description «Vintorez»

Silent sniper rifle VSS "Vintorez"

The sniper rifle can conduct both single and continuous automatic fire according to the good old principle of removal of powder gases from the barrel. The locking of this channel is carried out by 6 lugs of the rotary longitudinal sliding gate. There is a double-acting flag-type fuse, similar to a rifle fuse Svd: it locks the trigger and limits the action of the slide frame. Butt VSS «Vintorez» — skeletal type, detachable and made of wood. The entire rifle for hidden carrying and transportation can be disassembled and folded in a case.

A box-type rifle magazine has a capacity for 10 rounds (but the magazine from the automatic AS VAL 20 rounds), made of plastic. The rifle is equipped with an open-sight sights: a front sight and a sector-sight, located on the body of the muffler. For sniper shooting during the day, the PSO-1 sight is used, and for night shooting — ESPU-3.

The entire trunk in front of the forearm covers an integrated silencer.

The silencer acts as follows: after a shot, when a bullet passes the front of the barrel, a part of the powder gases rushes through six rows of transverse holes in the barrel into the expansion chamber of the silencer. The pressure of the powder gases in the barrel and their speed is reduced. A jet of powder gases flowing from the muzzle of the barrel, falls on the separator, which «dismembers» it on numerous multidirectional flows, intensively reducing their speed and temperature. As a result, the gases flowing out of the muffler have a subsonic speed and a low temperature, which does not create a clap and muzzle flame, and the shot becomes practically silent. The use of an integrated silencer has reduced, compared to a silencer that fits over the muzzle of the barrel, and the overall length of the weapon.
