SECTION III ALIGNMENT / ZEROING

2.15 ZEROING ON A 25-METER RANGE 2.15.1 Clip-On

.

WARNING..

Activating ZOOM 2X when the CNVD-T is used in-line with other optical sights may induce an error in the aiming function of those devices.

When being used in-line with an optical sight, the CNVD-T should be placed in ZOOM 1X, the reticle should be turned off, and zeroing procedures associated with the primary sight should be used. Placing the CNVD-T in front of an already zeroed optic / weapon combination does not necessitate rezeroing. 2.15.2 Stand-Alone

. Each click of the CNVD-T reticle moves the shot group about 2.8cm at 25m (when in ZOOM 1X). Other click equivalents are provided in Table 2-1. Changing the position of the 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

2-23

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.

a. Once mounted to a weapon, the distance from the top of the rail to the centerline of the CNVD-T objective lens is 5.9cm. 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 5.9cm + 3.1cm = 9.0cm down from the center of the target.

Figure 2-18 Strike Point Calculation

5.9cm

2-24

b. Mark the designated strike point on a standard 25-meter zeroing target.

c. Draw a designated strike zone around the strike point that corresponds in size to an acceptable degree of desired accuracy.

Figure 2-19 Designated Strike Zone

d. Mount the target on an “E” silhouette or other suitable surface at 25 meters.

e. Mount the CNVD-T to the weapon.

2-25

f. Turn on the CNVD-T using the startup procedures in section 2.11.

g. Align the CNVD-T reticle with the center of the target per paragraph 2.12.5.

h. Fire a 3-round shot group and note the center of the shot group relative to the designated strike point.

i. Adjust the position of the reticle to move the center of the shot group to the designated strike point.

j. Fire another 3-round shot group and again observe the center of the new shot group relative to the designated strike point.

k. When 2 out of 3 rounds are in the designated strike zone, the CNVD-T is aligned to be parallel with the rail of the host weapon.

. The throw-lever mounting bracket has a locknut that adjusts the tension required to clamp it to the weapon rail. It is preset at the factory but may need adjustment when initially mounted to the rail of the host weapon. If adjustment is required, the following procedures apply and are performed with the CNVD-T removed from the host weapon:

3-4

CAUTION.. Creating too much tension with the locknut may result in damage to the mounting bracket when the throw-lever is forced against the weapon rail. Creating too little tension with the locknut may allow for movement of the CNVD-T on the rail. Never completely remove the locknut from the mounting bracket.

a. Swing the throw-lever closed (against the body of

the CNVD-T), then push in the lever lock to engage the locking mechanism.

b. Using the provided 3/8” box wrench, adjust the locknut using slight movements (2 or 3 degrees). Turning the locknut counterclockwise will decrease tension on the throw-lever. Turning it clockwise will increase tension on the throw-lever.
