I have had 3 scopes recently that were forward of the bolt handle. An Alaskan, a Noske, and a Leupold Plainsman. The Leupold is probably the easiest to find and is petty cool in the fact that it doesnt have turrets. The adjustment is accomplished with rings that rotate on the tube itself. I wonder why they didn't really catch on?

I've got a picture of a Winchester 54 Hornet I can email if someone will post it for me.
