I own a lot of scopes. Leups, swar, nik, etc. For my go to hog gun I have a Trijicon TR22. The scope has a huge bell (56mm) and a little triangle for the sight. It also has a 30mm tube for ease of light transmission. That little glowing Triangle is coated with Tritium that glows in pitch black night. We have hog problems and they tear the crap out of the millet fields and rye grass we plant. Hogs are usually nocturnal or seem to come out just as it is getting real dark. I can even shoot with a half moon or good starlight. It is not battery operated so it is legal to whack them with it. My buddy uses my gun because his BLACK crosshairs are hard to use in a BLACK night and center on aBLACK hog. They are not cheap but not expensive either at around 750 to 800 dollars. It has accounted for 90% of the hogs I have taken with a gun and most of them I could not have taken a shot with a regular scope.
