I have never used a Sightron in the field but I have looked through one mounted on a rifle. It was definately bright and clear. I prefer Leupold but the last scope I bought was a Bushnell Elite 3200 3x9x40. So far I am impressed with this scope as well.

I will soon find out how tough this particular scope is. This evening I was lowereing my rifle down out of the stand and the pullup rope broke. The rifle fellscope firstfrom about 12 feet. From the outside there is no visible damage but I will be suprised ifit is still zeroed. I cleaned it off and put it back in the safe. As soon as the season is over I will seeif it's still shootin straight.
