A professionally built Argus PVS-31. (Frank @ Aeontac, professionally collimated with a Hoffman, and used Dioptrons for the internal diopters. Infinity stops set correctly. All of this is epoxied in place like a real 31. This keeps everything in order).

Inside are two amazing L3 18UA Unfilmed Green Phosphor tubes. These tubes will come with spec sheets. There are no emission points or bright spots, nor are there any spots or blems.

The skinny on the tubes:
RES: 64/64
SNR: 35.6/35.6
HALO: 0.7/0.7
EBI: 1.2/0.9
GAIN: 64309/64182 (Gain ratio of 1.001!)

This will come with what the Argus 31 housing came with. A carrying case (unfortunately, the top pocket has a tear), a battery pack and cable, neutral density filters, bikini covers, and eyecups. I will also be tossing in the tube containers that the tubes inside came in. This unit is 490g with a battery installed.

Can get more videos or pictures on request.
