Here are a couple pics of my M70 Stainless Classic in .338 WM with the Leupold Dual Dovetails and the Leupold 2.5-8 VariXIII scope. As you can see, the front ring uses the extended ring. It certainly is not the most elegant setup, but it works very well for me and in the approximately 15+ years I've had it, it has never gone out of zero or had any problems whatsoever. That includes travel to Africa, 3 or 4 trips to Alaska, and many local elk hunts. I only did it because I could not think of a more appropriate scope for a .338 and I love the M70s, so had to find a way to make it work.
