Side-mounted, 4x magnifying scope with battery-powered illuminated reticle calibrated for VSS marksmen rifle. Otherwise compatible with KA based rifles. In-game description
The PSO-1-1 Scope is a weapon attachment in DayZ.
Overview[]
The PSO-1-1 Scope is a fixed 4x magnification telescopic sight compatible with KA-based rifles. It is ballistically calibrated for the VSS marksman rifle, and by extension, the Vikhr assault rifle, as they (along with the SVAL, though it is incompatible with this optic) share identical ballistic characteristics, due to using the same cartridge – the subsonic 9x39mm.
If the optic is used on other KA-based rifles, such as the KA-M or the KA-74, an adjustment must be made to intentionally ‘undershoot’ targets, due to the much higher muzzle velocities. The proper amount of ‘undershoot’ must then be determined through practice.
The optic features an illuminated reticle and thus requires a 9V Battery for proper operation. (Otherwise, the crosshair and rangefinder are only faintly visible).
The PSO-1-1 Scope consumes 0.02 energy per second, therefore a single 9V Battery provides 42 minutes of active use.
Rangefinder[]
The PSO-1-1 Scope does not feature standard eastern ranging chevrons, instead relying on an in-built manual rangefinder for targets of 1.7m height.
The rangefinder is used by placing the target between the curve and horizontal line, in a manner that, with their feet on the horizontal line, the tip of their head touches the curve. The estimated range can then be read from the numbers visible on the horizontal line.

Trivia[]
- The PSO-1-1 Scope is directly modeled after the real-life PSO-1M2-1 Scope, originally designed for the VSS Vintorez with a max range of 400m
