Mounting Instructions
WARNING
Be sure the weapon is CLEAR and SAFE before
proceeding.
NOTE
The CNVD-T2 may be placed at any position
(forward and aft) on the rail that is most
convenient for the operator. If, however, the
CNVD-T2 is removed from the rail, the operator
should note the position at which it was zeroed,
and return it to that same position to ensure that
zero is retained.
1. Pull the lever lock out to the full open position.
2. Swing the throw-lever toward the front (objective lens) of
the CNVD-T2 to allow the mounting bracket sufficient
space to fit over the MIL-STD-1913 rail.

SECTION IV
ALIGNMENT / ZEROING
2.23 ALIGNMENT / ZEROING PROCEDURES
Clip-On
WARNING
When being used in-line with an optical sight, the CNVD-T2
should be placed in ZOOM 1X, the boresight reticle should
be turned off, and zeroing procedures associated with the
primary sight should be used. Placing the CNVD-T2 in front
of an already zeroed optic / weapon combination does not
necessitate rezeroing.
Stand-Alone
Each click of the CNVD-T2 reticle moves the shot group
about 0.7cm at 25m (when in ZOOM 1X). Other click
equivalents are provided in Table 2-1. Changing the position
of the boresight reticle corresponds to a subsequent change
in shot group movement (i.e., the UP button will move the
strike of the round up).
Table 2-1. Reticle Adjustments.
Single Click Equivalents
10m 25m 100m 150m 300m
ZOOM 1X 0.3cm 0.7cm 2.6cm 3.9cm 7.9cm
ZOOM 2X 0.1cm 0.4cm 1.3cm 2.0cm 3.9cm

2-23
(Continued)
When being used as a stand-alone device, the example
below shows how to align the CNVD-T2 to be parallel with
the rail of the host weapon on a 25-meter range. This
“infinite parallel” configuration is appropriate for many
mission profiles. Once parallel, the CNVD-T2 / weapon
combination may be zeroed in accordance with established
unit, departmental, or agency procedures.
1. Once mounted to a weapon, the distance from the top of
the rail to the centerline of the CNVD-T2 objective lens is
5.2cm. Calculate the designated strike point by adding
this value to the distance from the center of the weapon
barrel to the top of the weapon rail (3.1cm for an
M4/M4A1). Therefore, in this example, the designated
strike point is 5.2cm + 3.1cm = 8.3cm down from the
center of the target.
Figure 2-12. Strike Point Calculation.
5.2cm

2-24
(Continued)
2. Mark the designated strike point on a standard 25-meter
