Tri-shot
From Wookieepedia, the Star Wars wiki.
A tri-shot was a weapon attached to a B2 super battle droid's arm. It was used by them to take out large groups of enemy clone troopers. It shot three blaster shots in random directions, killing nearby enemies. A variant of the tri-shot allowed it to be used like a blaster pistol, and some members of Renegade Squadron used this variety.
