I've had an X-Sight II 5X for around a year now. It is mounted on a 12.5" 308 SBR with a Saker 762 suppressor. The included IR light is mounted on the rail using a Magpul M-lok extended rail. I have a TNVC thermal remote battery pack (
link) mounted to the X-Sight rail (I don't use batteries in the main unit at all). I modified the battery pack to remove the built in cable, the power cable that is supplied with the Anker battery works great with the ATN. The unit can run for two or three hours on a single power 'dot', probably would run around 8 hours on a single battery charge (4 dots). I have a second battery that I carry with me as they are small and cheap. The ATN was $425 shipped, the TNVC battery pack was about $103 shipped, and the backup battery was $20 shipped, totaling $548. I do have to purchase CR123 batteries for the IR light figure 2 batteries for $4 every 4-5 times it goes out hunting. It is a plus the unit can be used in Day Mode or Night Mode, one gun to take to the stand and I don't have to worry about Dad burning out a tube in bright daylight when I'm not there to supervise.
We have killed many hogs with this setup. The two below were from this past Saturday night about 40 minutes apart with solid cloud cover (no moon or stars), and 15 miles to the nearest small town, it was pitch black. With the IR set to low the bottom hog was clearly visible at the 135 yard feeder shown in the picture, Dad dropped him with a shot to the neck right where he stood. The top hog was shot at 85 yards by me. We feel comfortable shooting out to 200 yards using the IR light, after that we can certainly identify hogs vs. coyotes vs. cows vs. deer but aren't taking shots at them. We're just normal hunters so this meets our needs and has been much better than we expected.
