Funny thing, but I have had that NV Scope for many years and she never got much use. Mostly used as a demo unit, show guys what it looks like at various ranges.
Its an image intesifier and I understand thats now 'old tec' (As indeed am I). Young folk have both digital and that fangled heat stuff, thermal. Non the less, its better than digital cause it doesnt need IR illumination, so the fellas wont know your looking at them, sort of. Note the back up irons on the top. Bout as practicle as a chocholate tea pot.
Nor sure the 1894 in .357 is the ideal platform. Still, kinda cool, in a way.
