3.8.2.1 Elevation. - The line of sight through the boresight
cross (zero range line) shall be positioned above the geometric axis
of the telescope in accordance with the mil value indicated on the drawing
for the reticle utilized, withhin plus or minus 0.5 mils.
3.8.2.2 Deflection.- The line of sight through the boresight cross
of the reticle pattern utilized shall be in coincidence with a vertucal
plane that passes through thr geometric a is of the objective tube within
0.50 mils.
3.8.2.3 Coincidence of reticles.- The line of sight through the
boresight cross of the opposite reticle pattern shall coincide with the
line of sight of thr reticle position estabished in 3.8.2.1 and 3.8.2.2
within .07 mil.
