Koldt- Have you ever been able to look through those scopes at night, or do they have unobtainable batteries? Just wondering how well they worked, how clearly you could see and how far away?
Welllllll, I own a few of the AN/PVS502s. I think they are great! They use the N battery. Same battery as used with the Eotech scopes (other than the AA model), and are found everywhere.
I've also tested a lot of different NV scopes and can best compare the PVS502, with the U.S., PVS4.
They were manufactured by Varo, now Litton, in Texas around 1972ish. The resolution is approx 28 lp/mm. Not anywhere as good as today's stuff, like the PVS14, of 69 lp/mm. As per any early age starlight, they do have a bit of "fish eye".
All in all, for the money, I've said it a lot of times, these scopes are tough to beat and are perfectly adequate for engaging targets at most distances with very little moon light.
If you check the pic thread of the Swiss rifles, I posted a pic with one of these scopes on the Classic Green, with a Pic rail. The 502 is easily adaptable to any Picatinni rail and for proper eye relief and cheek hold.
The aiming reticule can be changed with any PVS4 reticule, including: 50cal, TOW, CarlG, 7.62(FN,M14 etc), 5.56, US M16reticule, Israeli reticule (that's in this one), and an observers reticule. The reticule is variable brightness and can be turned off, just for viewing.
Today's cost/value, I dunno.
