The PSO-1 scope (Pritsel Snaipersky Optichesky, "Optical Sniper Sight") is a weapon attachment featured in S.T.A.L.K.E.R.: Shadow of Chernobyl, S.T.A.L.K.E.R.: Clear Sky and S.T.A.L.K.E.R.: Call of Pripyat.
The PSO-1 scope is a magnified optical scope with a x2 magnification. The PSO-1 can be mounted on any Soviet or Russian made weapon such as the Akm 74/2 and the AC-96/2, and features the same magnification as the SUSAT Scope. Although unlike the SUSAT the PSO-1's view includes a more visible drop compensator system which, assist with shooting at distant targets.
The PSO-1 scope is mounted on the SVDm-2, but in-game can be mounted on any Warsaw Pact rifle or assault rifle. However, in Clear Sky and Call of Pripyat upgrades might be necessary in order to mount the scope.
Shadow of Chernobyl
Call of Pripyat
Shadow of Chernobyl
A widely used Soviet scope. The scope can be mounted on a weapon using a dovetail mount used by the Warsaw Pact countries.Shadow of Chernobyl in-game description
The PSO-1 scope can be difficult to obtain in the beginning both Shadow of Chernobyl. Bullet will give the player a PSO-1 Scope if the player assists him on his ambush against the Bandits in the Dark Valley. The box in Borov's office may contain the scope. Mercenaries in the Wild Territory use the PSO-1 scope on their Akm 74/2s, and some Loners in the camp in the Army Warehouses use this scope, such as Smartass. The Military begin to use it in the Red Forest, after disabling the Brain Scorcher.
The scope may be found in the following stashes:
Call of Pripyat
Standard x4 PSO-1 scopes can be found attached primarily to Dutyer rifles, as well as most Monolith and military soldiers using the AN-94 or AS VAL. Other versions are also available from traders. As usual, they don't give the weapon attached any bonuses aside from different sighting.
- x5 fixed zoom PSO-1M scope - The standard scope from previous games. In the Inventory screen, the lens portion is colored blue entirely for easy identification. Used by many Loners, Bandits, Duty members, Military soldiers, and Monolith fanatics.
- x2.7 PSU-1 scope - A close-quarters to medium range variant, with a fixed lower zoom. The lens portion has a small blue strip for identification. Sold by Owl in later stages of game and Hawaiian will sell if after assisting Freedom in faction war.
- x5 fixed zoom NSPU-3 image intensifier night vision scope - Variant with passive, 2nd-generation nightvision enabled. The lens portion is a bright green. Occasionally sold by Owl after doing his missions. Sold often by Hawaiian after siding with any of factions.
- x5 PSS-2X fixed zoom target optical scope with a built-in heat visor used to identify heat sources like the human body or mutants. - A scope with a built in target-identification system. Like the FT-200m and SVD's scope upgrades, it behaves like binoculars, locking onto and identifying subjects as friend-or-foe. Unlike the others, its end is a bright red. This is only sold by Hawaiian and the only way to obtain this scope is by getting the: A Wealthy Client achievement and a Friend of Duty achievement, along with that the scope will cost 11,000 RU. Note: A Wealthy Client achievement is not needed at later stages.
- There is a bug in Call of Pripyat with the Targeting and Night Vision PSO-1 scopes. When attaching either to a weapon and putting the weapon in a stash, the scope might turn into a regular PSO-1 scope. This can be avoided by keeping the scope unmounted while in stashes.
- Siding with Duty in Yanov will render the PSU-1 2.7x scope unobtainable from Hawaiian, but will be able to do so after siding with Freedom.
