105:. The main body of the mine is wine bottle shaped, with an NR 410 tripwire fuse screwed into a fuse well on the top of the mine. Under the fuse well is a detonator and a row of booster pellets. Wrapped around the detonator and booster pellets is the main charge. An internally square cross-sectioned steel wire is coiled around the outside of the mine, which give a fragmentation effect. The mine produces 600 fragments with a velocity of approximately 1,660 metres per second. It has an effective range of around 15 metres. A variant is produced with a cast steel fragmentation jacket.
