I'll agree with Michael on this one. Of course, every rifle I build (or have on the project list) is set up for iron sight position shooting under field conditions. Benchrest efficiency is not the driving factor here. Low combs and more drop at heel suit me fine. The last new M70 Featherweight I owned had a Lyman 48 and nothing else and my-oh-my, the looks I got at the gun range from the 'sniper wanna be' cognoscenti...
