BS-1

The BS-1 RGA-86 "Tishina" (Quietness) / BS-1M 6S1 "Kanarejka" (Canary) (romanized from БС-1 РГА-86 "Тишина" / БС-1М 6С1 "Канарейка") is a silenced grenade launcher system that was devoloped in the 70's. The idea behind a silenced grenade launcher system is that the user has more chance of escaping after launching the grenade.

Operation
The grenade is loaded into the muzzle of the barrel of the grenade launcher. It is then launched by the piston rod which is activated by a special launching cartridge based on a 7.62x54R round. The magazine is located in the pistol grip and loading is done manually by a longitudinally sliding bolt. The hollow-charge grenade can penetrate 15mm thick steel armor plate and weighs 1.7kg.
