•
Performance of the device in nighttime conditions depends on the level of ambient light in the
environment. Please remember the following:
— The level of ambient light is reduced by the presence of clouds, shade, or objects that block
natural light (trees, buildings, etc.).
— The equipment is less effective when operated in shadows and other darkened areas.
— The equipment is less effective when operated in rain, fog, sleet, snow, dust or smoke.
— The equipment will not “see” through dense smoke.

COT NM-108 BC
1.1.3 Purpose of Equipment
The COT NM-108 BC is a night vision system intended for use in conjunction with a daytime sight,
or riflescope (hereafter referred to as a “day scope”). When mounted on a weapon in front of an exist-
ing day scope, the NM-108 BC adds to the scope’s capabilities a night vision function (up to range of
900m), without affecting the boresight. Advisable day scope magnification values are 3 to 12X (4 to
10X are optimal).
The NM-108 BC is compatible with most commercial and military specification day scopes, and fits
any Picatinny MIL STD 1913 or Weaver rail via the quick release mount.
An optional long-range IR-illuminator enables use of the NM-108 BC in extremely low light condi-
tions or total darkness. Other additional equipment, such as an infrared laser, red dot sight, etc., may
