Sorry had a brain fart, it is 56 mm and around $2000 a pop at todays prices. I didn't say it wasn't way good, I said my binoculars are just a little better and it is irritating to be able to see farther in the dark (or low light) with the binoculars than the scope.

I'll grant you my binoculars are way heavy. So is my rifle. that sucker is around 9 pounds loaded.

I'm sure they have made advances, but it is still good scope.

Have you ever looked through a high end scope, with a large objective, at night?

Thermal or light gathering scopes, as well as spot lights are forbidden here. A good scope with a large objective is the next best thing for Boar hunting at night.
