Each boresight link has a pattern of holes that identifies the
type of testing it is used to perform. The 3-m link has a
3-hole pattern, the 5-m link a 5-hole pattern, and the
10-m link a 10-hole-pattern; the carrier includes a
corresponding pattern of holes indicating the correct
installation location for each.
To install a set of boresight links, match the hole pattern on
the links with the hole pattern on the carrier, remove the cam
pin, bushings, and knobs, install the desired links, and then
replace pin, bushings, and knobs.
The hole patterns on the carrier match
the hole patterns on the links
