The BH-4 Double Blaster, alternatively referred to as the Black Sun foot soldier blaster, represented a specific type of double-barreled blaster pistol. This particular model was favored by Black Sun enforcers, alongside members belonging to both the Black Sun Guard and the Captain of the Guard, namely Ziton Moj.
In terms of its conception, the Black Sun foot soldier blaster drew inspiration from comparable weaponry wielded by the robotic sentinels featured in the 1979 cinematic production, The Black Hole.
