BS-1 grenade launcher
The GSN-19 Kanarejka (Canary) is a "silent" underbarrel grenade launcher developed in the Soviet Union in 1970s. The GSN-19's standard projectile is a special 30mm AP-I (Armour Piercing – Incendiary) grenade designated as VOG-T. Unlike the VOG-25 grenade used in the GP-25, the VOG-T grenade has no propelling charge in itself. The system instead functions more like a rifle grenade launcher, using special blank propelling cartridges loaded into the GSN-19 from a detachable box magazine (which holds 8 rounds for the earlier 7.62mm based blanks and 10 rounds for the later 5.45mm based blanks). The blanks are fed into a chamber by a bolt-action mechanism. When the trigger is pulled, the blank fires, the gas pressure acting on a telescopic piston that extends from the breech to push the grenade out of the barrel. The piston is captive, and seals the expanding gases, which eliminates the noise and the flash (thus making the weapon a "silent" grenade launcher). It is functionally similar to the Soviet "silent" captive piston-based pistol cartridges (SP-1 to SP-4), save that the piston is part of the weapon rather than the case.
After a moment, the pressure drops to a safe level, and the weapon can be reloaded by loading in a new 30mm grenade from the muzzle and operating the bolt to eject the spent blank and chamber a new one.
The GSN-19 was adopted in a suppressed weapon system known as the BS-1 Tishina (Silence), and was a successor to Soviet Union's previous "Device D" and "Device DM" systems. Originally, the BS-1 system consists of an AKMS with a PBS-1 suppressor, subsonic 7.62 US ammunition, and a GSN-19 underbarrel grenade launcher with grenade launching sights. When the Soviet army switched to 5.45x39mm as their standard rifle cartridge, the BS-1 system was updated to an AKS-74UB with PBS-4 suppressor and GSN-19 grenade launcher. The GSN-19 itself was also slightly reworked, with its mounting brackets improved to better fit the AKS-74UB, and its launching ammunition switched over from 7.62mm-based blanks to 5.45mm-based blanks.
