I tried it last night with a friend's PVS-14. I was actually pretty surprised that it worked pretty well (but would never be confussed with the performance of one of the dedicated rifle scopes). I had to max out the focus to get a decent view, but I could see a stop sign and make out the details of a car (front window, rear window, etc.) at 185 yards! I could deginately put a round into the stop sign, assuming the POA is not shifted.. It sure beats moving the ACOG so far forward on the rail and you don't get the tritium bloom.
When my wife returns with my digital camera, I'll try some photos.
