7. A method for orienting an individual perforating gun assembly relative to other perforating gun assemblies in a string, comprising:
providing the perforating gun assembly including:
a gun housing including a first end and a second end opposite the first end, and an interior space between the first end and the second end,
a charge carrier positioned in the gun housing interior space, and retaining a shaped charge, in a fixed orientation relative to the gun housing, and
an orientation alignment ring connected to the gun housing first end in an unfixed connection state;
rotating the gun housing to a desired orientation relative to the orientation alignment ring;
fixing the orientation alignment ring to the gun housing first end by engaging a locking structure between the orientation alignment ring and the gun housing first end;
inserting an initiator assembly including an orientation sensor into an initiator holder on the charge carrier; and
connecting the perforating gun assembly to an adjacent, upstream perforating gun assembly, by connecting the gun housing second end to an orientation alignment ring of the adjacent, upstream perforating gun assembly.
