The Russian 1PN58 NSPUM scope is a "first generation" night vision optic that is an improved version of the 1PN-34 NSPU. Designed to be mounted on the standard Russian dovetail optics rail. This scope has an illuminated reticle powered by an LED rather than a bulb which is found on the earlier 1PN34.
The scope mounts very high on the rifle and requires more of a "chin weld" to align your eye with the eyepiece. It is a heavy and akward scope but it works well for its purposes.
