The projector consists of a 950 mm pipe with a spring inside. The spring is wound by grasping two handles next to the muzzle and pulling backwards, and is fired by an "ordinary trigger mechanism". The bottle or grenade being thrown is positioned unprotected above the pipe. The projector is equipped with a sight that has three rather optimistic settings: 50, 75, and 100 meters. In order to stabilize the projector, a monopod is provided.
The design is signed by Military Technician 1st Class Dugil.
