PPN-2

The PPN-2 is a night vision sight of soviet origin. The device is similar to the NSP-2 in function and form, but instead of being mounted on small arms such as assault rifles, it was designed for machine guns (PPN presumably standing for пулемет прицел ночной, or machine gun night sight). The device runs off of 9 volt as opposed to the NSP-2s 4.5 volt. Another noticeable difference is the IR floodlight (that looks identical to the NSP-2s IR light), mounted on the battery box, as opposed to the sight itself. It has a magnification of 3.5x and a field of view of 8°. The PPN-2 kit includes a carrier for the 6SC-25 accumulators used in the device. The PPN-2 was in use with many Warsaw pact armies such as the NVA, CSLA and LWP. The device is very similar to NSP-2. This is a trend that would continue with the NSP-3 and PPN-3 up to the 1PN34 (NSPU).[1]
