NOTE:
Optical axes of the NM-108 BC and day scope should align. It is not recommended for the dis-
tance between the axes to exceed 3 mm. If the difference in the axis heights of the NM-108 BC
and day scope above the weapon rail exceeds 3 mm, you will need to replace the day scope
mounting rings or monoblock.
The NM-108 BC on Picatinny rail in front of a day scope is shown in Figure 3-3.
Install the NM-108 BC on a Picatinny / Weaver rail in front of a day scope as follows:
1. Remove the output lens cap and place it in the storage case.
2. Remove the light suppressor from the storage case. Put it on the output lens in place of the cap.
3. Unlock the clamping device of the NM-108 BC mount by pushing down on the dogs (A, see Fig-
ure 3-4) and unlocking the levers (B).
4. Install the NM-108 BC on the Picatinny / Weaver rail in front of the day scope so that the stops
(A, Figure 3-5) slide into the transverse slots on the rail. The light suppressor should cover the day
scope’s objective lens.
5. Affix the NM-108 BC to the rail by locking the levers (B, Figure 3-4).
6. Verify that the clamping device is firmly holding the NM-108 BC. If necessary, adjust the clamp-
ing device’s lever-cam locks as detailed in Part 3.1.4 (Clamping Device Adjustment).
