PK122 is designed to reduce the time of aiming at the target and improve the accuracy of small arms shooting during the daytime at dusk, as well as at night when used together with a night vision monocular.

Improvements compared to the previous PK 120 model:

• New design using mirrors.

• Ergonomic design.

• Easy cleaning of the eyepiece.

Since 2019 PK122 is used with infantry combat system Ratnik.
