The PSO-1 ( ????????????????????, Pritsel Snaipersky Optichesky , "Optical Sniper Sight ") is a telescopic sight produced in Russia by the Novosibirsk instrument manufacturing plant (NPZ Optics State Plant) and was issued with a Russian military dragunov sniper rifle.
PSO-1 was, at the time of its introduction around 1964, the most technically advanced telescopic view ever designed for snipers determined by mass production or sniper rifles.

Design
The PSO-1 is specifically designed for SVD as a telescope sight for a military-designated snipper activity. Current vision version is PSO-1M2. This telescopic vision is different from the original PSO-1 simply because it does not have an outdated infrared detector. The metal body of the PSO-1 is made of magnesium alloy. PSO-1 has a battery-lit red reticle with light provided by a simple diode lamp. It features professional ground, fully coated multi-optical elements, baked enamel finish for initial protection, and an inherent, fast-deployable, extended blinds.
The scope is sealed and filled with nitrogen, which prevents optical fogging and is designed to work within a temperature range of -50 ° C to 50 ° C. To center the telescopic view the reticle can be adjusted by manipulating elevation and windage turrets within a distance of 5 cm at 100 meters (0.5 mile or 1.72 MOA).
Considered to be the tip of a telescope higher than the Soviet military side, the PSO-1 quality is higher than most other PSO-style telescopic scenes. PSO-1 has no adjustment of focus or parallax compensation control. Most modern military tactical spheres with lower low power enlargements such as ACOG, C79 or SUSAT optical sight (intended for quick close range shooting rather than long range shooting) also do not have such features. Modern fixed magnification of high-end military-grade sniper telescopic scopes intended for long-term firing usually offer one or both of these features. The position of the body of the scope to the left of the boring midline may be uncomfortable for all shooters.
Row of compensation decrease of bullet drop
Turret elevation PSO-1 has a bullet drop compensation feature (BDC) with an increase of 50 m or 100 m for points of interest and target areas in the range from 100 m to 1,000 m. At a further distance the shooter must use chevrons that will shift the path by 100 m per chevron each. The BDC feature must be set in the factory for a particular ballistic path from a specified combination of rifle and cartridge at specified air density. BDC induced errors will occur if environmental and meteorological conditions deviate from a calibrated BDC state. Marksmen can be trained to compensate for these errors.
In addition to BDC elevation or reticle vertical adjustment controls, reticle or reticle adjustment controls can also be easily contacted by users without having to remove turret caps etc.
Reticle
PSO-1 features a reticle with "floating" elements designed to be used in estimation of range and decrease of bullets and drift compensation (see external ballistics).
The top "chevron" (^) is used as the main sign. Horizontal hash marks are for windage and lead correction and can be used for a variety of purposes as well.
On the left is a stadiametric stalker that can be used to determine the distance of the object/person height by 1.7 meters (5 feet ft 6.9 inches) from 200 m (2) to 1000 m (10). For this the lowest part of the target lined up in the lower horizontal line. Where the top of the target touches the curve over the distance can be determined. This reticle layout is also used in several other telescope spots produced and used by other Warsaw Pact countries.
Three lower chevrons in the middle are used as point handles to pull the target area beyond 1,000 meters (setting the maximum BDC range on the elevation drum). Users should set up an elevation tower of up to 1,000 meters and then apply each chevrons to 1,100, 1,200 or 1,300 meters.
Reticle 10 reticle in a horizontal plane can be used to offset wind or move targets and can also be used to determine additional stadiametric range, since they are spaced at 1 miliradian intervals, which means if an object is 5 m wide it will appear 10 Hash width at 500 m.
The reticle may be illuminated by a small battery-powered lamp.

Installation system
The telescopic distance display is adjusted for tension on the rifle rifle side rails. This side rail is a Warsaw Pact rail (a kind of fitting rail). The side rail installation is an offset mount that places the telescopic axis of the PSO-1 to the left side in relation to the receiving center axis. The mounts have a screw castle nut to the bottom of the locking lever. The spring part of the clamp must be pressed to tighten or loosen the castle nut as required.
The telescopic sight is a factory that matches the rifle by carving the serial number of the scope into the SVD rifle ass stock. Russian commercial Tigr rifle (based on SVD military rifle) has a serial number of rifles engraved on the side of the scope of PSO-1M2.
Accessories
PSO-1 is removed with a lens hood that can be attached to the ocular to reduce/eliminate image quality that damages lost light and bag to protect vision during transportation and storage.
