This grenade was produced in 1991 in the factory "TTM-TTS" in Sisak,Croatia. The first matrix for this grenade was made in a small private gun workshop "Jelen" in Turopolje, Croatia.
The production was going very slow so it was decided to move the production to factory TTM-TTS who had the technology for making grenade bodies from cast iron.
Daily production was about 400 grenades. The body of the grenade was made from two pieces of cast iron,which were brazed together.The grenade body had internal fragmentation like Yugoslavian M52 grenades.
