INTRODUCTION
Technical Description and Service Manual of the 7. 62-mm Dragunov sniper
rifle (SVD) is intended for studying the rifles and optical sights and
keeping them in constant fighting ready for action.
This paper includes specifications and data of the rifle and optical sight
design and operation, as well as main rules necessary to provide for the
proper maintenance of the rifle with the sight and full using of their
technical capabilities.
Since efforts are continuously made to improve the rifle and its
completing articles, minor changes in the Technical Description
may be introduced without special notice.
1. TECHNICAL DESCRIPTION
1.1. Purpose of rifle
1.1.1. The 7. 62-mm Dragunov sniper rifle is a
sniper's weapon and is designed to destroy various single targets,
which may be collapsible, moving, open and screened (Fig. 1).
The sniper optical sight is intended for precise
aiming of the sniper rifle at various targets.

1.1.2. The sniper rifle uses rifle cartridges with ordinary, tracer
and armour-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.
1.2. Technical data
1.2.1. For basic ballistic and design characteristics of the rifle
and the rifle cartridge and for design data of the optical sight refer
