I have one of these stocks and it is hands down my favorite big game rifle, mine has a Sako AV action with a Shilen barrel that is a slightly larger contour than the factory barrel was (not sure what # it has been a few years). the barrel is .760" at the tip of the stock and the flat on top of the stock at the tip is 1" at 10.750" ahead of the action.
Hope this helps, B
