BS-1 Tishina

The BS-1 RGA-86 "Tishina" (БС-1 "Тишина") / BS-1M 6S1 "Kanareyka" is a silenced Soviet 30mm grenade launcher. It was developed specifically for the Spetsnaz. It uses a bolt-action mechanism to load blanks into the chamber along with the 30mm grenade VOG-T (ВОГ-Т). Pulling the trigger ignites the blank which in turn ignites the charge on the grenade causing the grenade to be expelled from the barrel.
