The sight is mounted on a weapon with a seat - a guide like Picatinni, and can also be mounted on a weapon with a side bar by means of a transitional bracket.
The sight can be operated in the temperature range from minus 40 to 50C, relative to air humidity up to 98% and atmospheric pressure from 60 to 107.6 kPa (450 to 800 mm Hg).
When operating the sight at temperatures from minus 18С to minus 40С it is recommended to use lithium power supplies.
It is produced in 2014.
Index GRAU - 1P87
It is part of the complex of DPSK (day-night sight-observation complex) of the experimental design work "Ratnik".
Currently, according to the leadership of the manufacturer (ZAO Zavod JUPITER), it is supplied to the troops, but in fact it was supplied only for military tests with new automatic rifles on the subject of the Rocket "Rocket", where there are very large censures of the military on his work.
Characteristics of the sight of the collimator "Valdai PK-120":
Increase of sight, 1
The field of view when the eye is removed at a distance of 100 mm from the exit window of the sight is deg - 10.5

Overall dimensions, not more, mm - 135x68x72
Weight of sight without battery, kg - 0,3 + -3%
Operating temperature range, С - from minus 40 to 50
The sight has a working mode with night vision devices.
The sight has 9 levels of brightness adjustment of the aiming mark.
The sight has no parallax at a range from 100 to 200 m.
The range of alignment of the aiming mark relative to the optical axis of the sight in the horizontal (П Л) and vertical (В Н) directions is not less than + - 10 etc.
Reconciliation step - 0,25 tons.
Leaving the line of sight in a direction perpendicular to the reconciliation, in the entire reconciliation range, not more than 0.3 tons.
The supply voltage is 1.5V (type AA source).
The operating time from a single power source under normal climatic conditions is not less than 100 hours at the 7th stage.
The sight is resistant to mechanical impacts of a single action with a peak shock acceleration of 300 G with a duration of 1-3 ms.
The sight can withstand a short immersion in water at a depth of 1 m without loss of efficiency.
The sight has a mechanical reverse polarity protection when the power supply is incorrectly installed.
Warranty period of the sight: 12 months from the date of commissioning of the product.
Device and work:
The sight is an optical-mechanical device, the principle of which is based on the formation of the image of the aiming mark in the target area.
The sight consists of the body 1 and the prismatic block 2. The following elements are located in the body:
Handle 3 - on-off and brightness control with the function of a smooth transition from day mode to night vision mode and back
Battery compartment, closed with a lid 4, fixed to the casing 1 with a cable 5.
Landing place for installation of a sight on a bar of type "Picatinny", consisting of a clamping bar 6 and the screw 7.
Mechanisms of alignment 8 horizontally (П L) and 9 vertically (B Н).
