1. A muzzle-end adapter for bore sighting of large caliber guns, the muzzle-end adapter comprising:
a main operating shaft extending along a first longitudinal axis;
a disk, wherein the disk is mechanically coupled with the main operating shaft, wherein rotation of the main operating shaft provides rectilinear motion to the disk;
a main body lying substantially along the first longitudinal axis, wherein the main body encapsulates the main operating shaft, wherein the main body comprises:
a first-section,
a second-section, wherein the second-section comprises a plurality of sets of centering fingers, wherein the second-section encapsulates the disk; and
a plurality of conical disks, wherein the plurality of conical disks comprises a first conical disk and a second conical disk, wherein the first conical disk is positioned at a second end of the second-section, wherein the second conical disk is positioned at a first end of the second-section,
wherein rectilinear motion of the second-section over the plurality of conical disks radially expands one or more centering fingers of the plurality of sets of centering fingers.
