Silent sniper rifle “exhaust” is designed to TsKIB SOO (Central Bureau of sports and hunting weapons, Tula Instrument Design Bureau branch) in 2002, by special order of the Special Purpose Centre (TSSN) Russia’s FSB. Rifle (or more accurately – sniper complex FSI / VSSK “Exhaust System” consisting of weapons and ammunition, GRAU 6S8) was first publicly demonstrated in autumn 2005 at the exhibition Interpolitex in Moscow. It is known that complex “exhaust” is released in small quantities and is in service units TSSN Russian FSB.

The main purpose of a sniper rifle SCD / VSSK “Exhaust” is silenced and flameless defeat hard targets (vehicles, other non-armored vehicle, a living force in heavy body armor or ukryvshayasya in vehicles, etc.) at distances up to 600 meters. At the same time through the use of bullets at subsonic muzzle velocity (about 290-295 m / s) in combination with an effective silencer provided a significant reduction in sound of a shot (a shot at the volume level of 123 dB). Most efficiency of the target achieved by using heavy heavy bullets weighing 59 gram (chuck SC-130PT high accuracy) and even 76 gram (chuck SC-130VPS with high penetration). For patron SC-130PT states grouping 25mm at a range of 100 meters (1 MOA / angular minute), for cartridge SC-130VPS – guaranteed penetration 16mm steel plate at a distance of 200 meters or heavy armor protection class 5 (GOST) at a distance of 100 meters . The cartridges use specially made bullets and cartridge cases are relatively short cylindrical shape – the total length of 12.7mm rounds CC-130 is 97mm against 145 mm for “normal” national caliber cartridge 12.7h108. Because of the relatively small (for the chosen caliber of course) muzzle energy weapons under him has been almost two and a half – three times easier than the rifles under the “conventional” large-caliber bullets or 12.7h108 12.7h99. Nevertheless, the muzzle energy of a bullet cartridge SC-130PT is the order of 2500 joules (3650 J Cartridge for SC-130VPS), and due to heavy bullets with high ballistic coefficient energy is better preserved on the trajectory of the bullet compared to “normal” sniper rounds 7.62mm or “silent” 9mm bullets fired from a rifle VSS “Vintorez.
It should be noted that such a development (large-caliber rifle at a special low noise “weakened” cartridge) is not unique. Back in the mid-1990s in the U.S. well-known expert on special cartridges JD Jones (JDJones) working in the company SSK Industries, created the bullets .500 Whisper, used the shorter sleeve from a hunting rifle cartridges .460 Weatherby Magnum, coupled with precise bullet caliber 12.7mm, which had excellent ballistics. Muzzle velocity and mass of the bullet cartridges .500 Whisper comparable to those of 12.7mm ammunition SC-130, but apply them in a specially upgraded shop or singly rifles (created based on the game), equipped with a silencer and telescopic sight. In addition to bullets Whisper series of limited released in the U.S., and other munitions and weapons of similar use and size, but reliable information about whether to apply such weapons intelligence agencies or law enforcement offices in the U.S. and elsewhere, no.

The is a special large-SCD / VSSK “exhaust” is built in the build Bullpup and has an integral silencer, removed for transport or cleaning weapons. The mechanism of reloading manual with a longitudinally sliding gate, controlled grip on the right side of the weapon. Locking barrel by turning combat lichnikoy shutter. Inline detachable box magazine holds 5 rounds. The receiver rifles are made from the top mount for optical or night sights, in addition, rifle equipped with backup iron sights (front sight and rear sight), performed on folding bases. In front of the short plastic forend is a folding bipod.
