I also have the ATN X-Sight 2, and while the technology is "neat" it is very cumbersome. I don't know if others have the same problem, but I find that since there is basically no eye-relief, it is really awkward at times to set up for comfortable shooting.
The ATN 4k might be a better option, but I have not shot one of those. I know that when ratting at night, I have had success with a red flashlight and scope (inside 25 yards).
Best of luck!
