I'am in the market for a night vision scope. I would think that the ATN PS-22 would make a great system. It could go to and from any gun with a adapter, and use your daylight scope.

I have one. I like it.

Mines the GCT (2nd gen selected or better resolution). I can see well even on moonless nights in open fields with the illuminator out to about 80 yards on rabbit-sized objects. The clamp to attach to the day scope works fairly well.
