The Bushnell 4200 2.5x10 is built like a tank, and weighs like one as well. It's been around for a very long time,just with a different name. But it's a lot more reliable then any thing else. You just can't boast.
At that price point scopes are meant for once a year hunters.
I have VX-2 2x7 . I guess I should take it and the mighty 260 to the range and see if it goes loose again before the hunting season, chuckle.
