1.1.2. The sniper rifle uses rifle cartridges with ordinary, tracer and
armor-piercing-incendiary bullets or rifle sniper cartridges. The fire
is delivered in single shots.
1.1.3. The optical sight permits to conduct night firing at infrared
sources and under bad conditions of illumination, when it is difficult
to fire at targets with the open sight.
When observing the infrared sources, the rays radiated by the source
pass through the sight objective and effect the screen, located in the
focal plane of the objective lens.
In place of acting the infrared rays luminescence appears on the
screen. It results in a visible source image in the form of a round
greenish spot.
