• a safing sector slide member configured to slide forward and rearward relative to the safing sector cover and including a concave locking shelf;
• 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, the safing sector slide control mechanism includes a locking arm configured to impart forward and rearward sliding movement of the safing sector slide member relative to the safing sector cover, and a locking mechanism pivotally coupled to the locking arm and including a distal end terminating in a convex locking mechanism shelf stop to push on and engage the concave locking shelf of the safing sector slide member to lock the locking arm and the safing sector slide member in the fire position.
