If I may, there is one first gen weapon mount optic that does work pretty well decent clarity(36lpm), for its age and thats the pvs2, its big its heavy , it has a bastard type mount for those who cant machine up adapters,and you can still get parts for it,the but, for what it is, and the prices I have seen them going for now days, compared to what they were in the 80s, its not that bad of a unit, yes once you look through a 3rd gen unit, you are ruined till you get a 3rd gen unit, (which, Im currently working hard at saving for), just thought I would mention that, having had a 2 for 20 some yrs, it has worked for me, and I will still hang on to it after I get a 3rd gen unit,
and having picked up one of victors IR torches, it has given my pvs 2 a second breath, till I get a 3rd gen unit,
