Introduction
The crew of the Bradley fighting vehicle expects the 7.62mm coaxial
machinegun to aim and fire at the same target as the 25mm gun.
Therefore, the line of sight of the 7.62mm machinegun must be aligned
with the line of sight of the 25mm gun.
This alignment is
accomplished during the boresighting process. Once the 25mm gun has
been boresighted, the 7.62mm coaxial machinegun can be boresighted to
the same aiming point.
This task describes
the
procedures
for
boresighting
the
7.62mm
coaxial machinegun.
2.
Boresighting the Coaxial Machinegun
a. The procedure for boresighting the coaxial machinegun is
similar to the procedure for boresighting the 25mm gun.
In this
case, however, the gun reticle should already be on target.
The
boresight adapter and telescope are installed in the machinegun, and
the boresight controls for the
