PSO-1 Scope

The is a telescopic Sight with optional illuminated reticle for the KA-M, KA-101, KA-74, VSD and VSS in DayZ Standalone. The provides a reduction to the weapon's dispersion cone, increasing the overall accuracy of the weapon. It also provides additional zeroing ranges, allowing the survivor to make more accurate shots at longer ranges. The also features a functional range finder situated to the lower left of the aiming reticle. The is also the only scope to feature an optional illumination feature.

The consumes 0.02 energy per second and therefore consumes one battery every 42 minutes of active use.

Performance
The performance table below shows improvements or reductions in the various aspects of a weapon's performance. The base column is the named stat of the listed weapon with no attachments.

Range Finding with the
The PSO-1 features a reticle with elements designed for use in range estimation, bullet drop and drift compensation. These features are completely functional in DayZ Standalone.

The top center "chevron" (^) is used as the main aiming mark. The horizontal hash marks are for windage and lead corrections and can be used for ranging purposes as well.

To the left is a stadiametric rangefinder that can be used to determine the distance from a 1.7 meters (5 ft 6.9 in) tall object/person from 200 to 1,000 meters. For this the lowest part of the target is lined up on the bottom horizontal line. Where the top of the target touches the top curved line the distance can be determined.

The three lower chevrons in the center are used as hold over points for engaging area targets beyond 1,000 meters. The user has to set the elevation turret to 1,000 meters and then apply the chevrons for 1,100 meters, 1,200 meters or 1,300 meters respectively.

The 10 reticle hashmarks in the horizontal plane can be used to compensate for wind or moving targets and can also be used for additional stadiametric rangefinding purposes, since they are spaced at 1 milliradian intervals, meaning if an object is 5 m wide it will appear 10 hashmarks wide at 500 m.

Trivia

 * The  is also mounted on the SVD in ArmA 2 (and the DayZ Mod) and references the SVD in its description.
