This fuze is a practice fuze for the 81mm M879 practice cartridge.
The fuze has an aluminum body with an M734 multi-option fuze ogive or an M935 PD
fuze ogive, a pyrotechnic smoke cartridge, a striker, and an arming mechanism.
During forward acceleration, the setback pin moves rearward. This action allows the slider to move radially outward. The striker is released and a steel ball is inserted between the striker and pyrotechnic smoke cartridge. On impact, the striker drives the steel ball into the percussion primer of the pyrotechnic smoke cartridge. The smoke cartridge functions and produces a flash, an audible sound, and a smoke cloud.
