Night Vision Reccomendation needed

[gtty]

Ok, so I'm floating here offshore of Canada watching Tropical Storm Maria steam towards us and am thinking of rewarding myself for my month at sea with some type of night Vision scope to put on my Retro M16 Kit (now a semi AR15). I need something in to $300-450 range that will mount to my carry handle. Do y'all have any suggestions? I'm going to go piggy hunting with it.

I had one of these on an AR carbine back around 20 years ago and the guy I sold it to still uses it a once or twice a year for Coyote hunting. I have seen them listed in the $350 range. Oh yeah, it's an ATN Aries MK-238.
Another friend of mine was talking about selling his this past spring.
