PPN3 gen 1 Polish night vision scope that was originally designed for the PKMN machine gun. However, it fits all guns that have a side rail, such as AK and Dragunov. It is altogether in good working order and has clear picture quality, it has a canvas carry bag and has two daylight filters. The reticle bulb and reticle also function correctly, batteries are very rare and not widely circulated, the system operates off of four volts but works the same if two aa batteries are wired together. Rare to find and good collectible item. No trade, prefer local sale, dont accept lowball offer.
