huntinhard,
I finally finished with the day and got to measure some of these scopes. Best to worse............
Bushnell 6500 4 1/2-30X x4 1/2=2 3/4" 30X=2 3/4"
Weaver V24 6-24X 6X=2 3/8" 24X=2"
Sightron II 3-15X 3X=2 1/8" 15X=1 15/16"
Tasco 6-24X 6X=2 1/8" 24X=1 13/16"
Tasco 4-16X 4X=2 3/8" 16X=1 7/8"
Four of my friends told me the Tascos are clearer than the Sightron II. They were allowed to adjust to thier hearts' content. I thought the Sightron II was better than the Tascos. But I paid $75 for one and $99 for the other Tasco, and I paid $411 for the Sightron II. Maybe that influences my eyes.

I hope this info is benificial.
I didin't realize the Tascos are as good as they are or the NightForce is as bad as it is. Never the less, I don't have to concern myself with getting hit by the NightForce since it is on my heavy barreled .224 MBOC.
