[Source] The Blaster buster was a small and highly specialized niche slugthrower. The Blaster buster was a palm sized slugthrower designed to incapacitate an attackers blaster rather than to kill. Containing only a four round clip, the weapon could be fired in the general direction of a target, the special repulsor driven rounds seeking out the ionized particles that clung to recently fired blasters. So long as the target was in the general area, as well as in direct line of sight, the round would seek out the blaster.
