Thanks for your replies.....as an update, I've ordered the Sightron. Why? Well, first I wear glasses on occasion and the eye relief was greater on the Sll. Two, there was a small (2) mm increase in the O diameter. Three, This boards great people and their generous opinions. And 4, my always trying something new.
It's going on a Remington 700 LSS Mountain Rifle in 30-06 that I'll use for elk next year in Colorado. I already have a .280 in the same platform (execpt no laminated stock) that I really care for, but I'm kinda freaky for Laminated stocks. Who says you really need a good reason for adding a rifle to a collection anyway!
Merry Christas to all, and thanks for you help Rocky
