Abstract: A gun control unit for a M134 minigun firearm including an armature and a stator comprising at least one hardware processor; and one or more software modules that are configured to, when executed by the at least one hardware processor, independently control the armature; independently control the stator.

Abstract: A safing sector for a minigun including a housing with an opening adjacent to barrels of the minigun, comprising a safing sector cover configured to cover the opening of the housing of the minigun; one or more retaining pin assemblies configured to retain the cover to the housing of the minigun; a safing sector slide member configured to slide forward and rearward relative to the safing sector cover; a safing sector slide control mechanism configured to impart the forward and rearward sliding movement of the safing sector slide member relative to the safing sector cover between at least a fire position and a safe position, where the barrels of the minigun may be rotated electrically without firing and without bolt assemblies becoming damaged.

Abstract: A cooling rotor for a minigun that actively pulls gases and heat generated from firing the minigun comprises a front end with an axial opening; a rear end; a bore extending from the rear end to the axial opening in the front end; a plurality of longitudinally spaced, peripherally extending rotor segments; and one or more openings disposed between two or more of the plurality of longitudinally spaced, peripherally extending rotor segments whereby upon rotation of the cooling rotor gases and heat generated from firing the minigun are actively pulled through the one or more openings, the bore, and out the axial opening in the front end.
