The Soviet PSO-1 (Pritsel Snaipersky Optichesky, "Optical Sniper Sight") telescopic sight was, at the time of its introduction (around 1964), the most technically advanced telescopic sight ever designed for a mass-production designated marksman or sniper rifle. The PSO-1 telescopic sight is manufactured in Russia by the Novosibirsk instrument-making factory (NPZ Optics State Plant) and is issued with the Russian military SVD sniper rifle.
Battlefield: Bad Company 2Edit
Battlefield: Bad Company 2: VietnamEdit
The PSO-1 is seen on the SVD sniper rifle in Battlefield: Bad Company 2: Vietnam. Like it's counterpart on the base game's SVU and VSS, it has a 6x magnification and has a unique reticle with stacked chevrons for gauging bullet drop at range. It has considerably more zoom than the M21's scope, and the same zoom as the M40, but unlike the others, it does not allow the player to use peripheral vison while sighted in.
Zoom magnifies 1,95x
The PSO-1 is a weapon attachment featured in Battlefield 3 that provides 4× (346%) magnification. Unlike the sniper's default PKS-07 scope, the player will not suffer from scope glint. It cannot be mounted to PDWs, besides the AS VAL, due to complications with the amount of space available on most PDW attachment rails, but it can be mounted to all other types of primary weapons in game.
The PSO-1 features a stadiametric rangefinder in the lower-left side of the reticle, but it is not accurate in-game.
The PSO-1 returns in Battlefield 4 as it was seen during the E3 2013 livestream of the game's multiplayer.
The appearance of the PSO-1 is similar to the one in Battlefield 3, but with a major difference being that the top chevron is marked red unlike the other chevrons, which are still black. It also appears that the stadiametric rangefinder may be gone, though there are few reference images available.
