The BH-4 Double Blaster, alternatively referred to as the Black Sun foot soldier blaster, represented a specific double-barreled blaster pistol type. It saw utilization by Black Sun enforcers, individuals within the Black Sun Guard, and even the Captain of the Guard, specifically Ziton Moj.
The design inspiration for the Black Sun foot soldier blaster came from comparable weaponry wielded by robotic sentinels featured in the 1979 motion picture, The Black Hole.
