18. A method, comprising:
providing a plurality of perforating guns, each perforating gun comprising a gun carrier having first and second ends and defining an interior therethrough;
installing a bulkhead in the interior at the second end of a first of the gun carriers of a first of the perforating guns and engaging a flange on the bulkhead against a distal face on the second end, the first gun carrier having an external tapered thread defined externally on the second end, the bulkhead having a feedthrough conductor passing therethrough;
installing a charge holder in the interior at the first end of a second of the gun carriers of a second of the perforating guns, the second gun carrier having an internal tapered thread defined in the interior at the first end;
electrically connecting between electrical components at an end connection between the first and second gun carriers by threading the internal tapered thread defined in the interior at the first end of the second gun carrier to the external tapered thread defined externally on the second end of the first gun carrier; and
capturing the flange between (i) the distal face of the second end of the first gun carrier and (ii) an internal shoulder of the first end of the second gun carrier connected at the end connection.
