Let’s just get this out of the way right now; it is irrelevant what type of generation you invest in, you are allowed to own a pair of night vision goggles. Given their advanced optics and technology, it can be easy to ask yourself if the technology you are donning is legal. But, it is. Any average civilian can own one and you do not have to be registered in any way (as long as you are a United States citizen). No law enforcement background is required or anything like that.
Then again, there is one critical mistake that you need to avoid. Otherwise, you will be violating the law and could end up in serious trouble.
