Hello everyone. My brother just bought an Eotech 553 for his AR. I was thinking about buying him a late Christmas present. I honstly have to say I know nothing about NV optics. All I do know is that his Eotech is NV compatiable. What would the experts suggest I should buy him to mate to his Eotech for hog hunts at night ? I don't want to spend too much as he will only be using this set up a few times a year. If you could please post model and average cost, if you know, I would appreciate it. Thanks again and Happy New Year everyone !!
