Zachary,
I believe he has an M96 Swedish 6.5x55mm Mauser long rifle. Because of requirements for drilling and taping a receiver mount and problems with mauser bolt (straight) and safety lever clearences, he is looking for a scout scope, mounted on the rear sight base (B-Square Mount), and will probably need somewhere around a 12-15 inch eye relief. Hope this clears up the issue.
