NIGHT OPTICS USA WEAPON SIGHTS
Note:
The effective detection and recognition range of NS-520 is dependent on the amount of ambient light,
magnification of the scope, atmospheric transparency, and contrast between the target of observation and
its background. In high ambient light (moonlight) with the target against a light background (sand or snow),
the effective range is increased. In low ambient light (overcast) with the target against a dark background
(trees, brush, etc.), the effective range is decreased.
