Has anyone ever tried to take the PVS-7 lens out of their housing and compared it to the PVS-14 objective lens? By comparing photos online, it looks like the 7 has the same pitch and thread for the focus and even the same lock ring to hold them in the housing as the 14.
UPDATE: Got the PVS-7 lens in today and tried t out. First to keep the o-ring in the housing, I turned the stop ring on the objective lens the wrong way with the lip facing away from the image intensifier. Worked like a charm.
There's a park that's about 300m away from my house across an open field and the poles and lights there are a little blurry but can still see well enough for a bugout bag/loaner/beater NV optic.
I am still on the lookout for a good used PVS-14 objective lens.
With the WP tube and this particular housing, I seem to have lucked out and the houses and park at 300m ish are in focus.
