The PSO-1 (Прицел Снайперский Оптический, Pritsel Snaipersky Optichesky, "Optical Sniper Sight") is a telescopic sight manufactured in Russia by the Novosibirsk instrument-making factory (NPZ Optics State Plant) and issued with the Russian military Dragunov sniper rifle. The PSO-1 was, at the time of its introduction on 3 July 1963 together with the Dragunov sniper rifle, the most technically advanced telescopic sight ever designed for a mass-production designated marksman or sniper rifle.
