I saw one recently , a Vision Master 56 . The objective was around 4" , the tube was 40-mm . The intensifier was detachable . Its a huge rifle-scope . Are they any good ? Has the military used them ?
Will definitely post tomorrow. The revival stemmed from a small scour of the internet searching for info on the optic. The one I’ve got has some spotting in the reticle but nothing visible on the surface of either lens
