1. BRIEF DESCRIPTION
NC 3-12x50 is the daytime riflescope with variable
magnification, which is designed for being used on
various kinds of weapons.
The Mil-dot reticle of the riflescope is positioned in
the focal plane of the eyepiece (second focal plane),
thus providing permanent size of the reticle
regardless of the riflescope variable magnification.
This creates favorable conditions for acquisition of
small targets at long distances, due to the fact that
the reticle covers only small portion of the target at
large magnification.
The riflescope is equipped with central system
parallax adjustment, which works for ranges from 50
meters to infinity.
The reticle is highlighted with red LED with seven
modes of brightness.
The riflescope incorporates windage adjustment (the
multi-revolving scheme) and elevation (single-
revolving scheme), allowing to adjust shooting
ballistics in wide range.
