  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.

  1.2.1. For basic ballistic and design characteristics of the rifle and the rifle cartridge and for design data of the optical sight refer to Table No. 1.
