I had an Armasight Nemesis gen 2 6x with quick silver. I killed a sow at 360 yards using a UNV 20-IR on a moonless night. You can spot objects a good deal father away that that but not be able to positively identify them until you get closer. The 6X is okay, but for closer work I'd recommend the 4X. The 6x limits your field of view at closer ranges.
