I have a Sako 308 rifle and a Kahles 642i scope(34mm tube) I need a single piece scope mount . The rail on the sako is a unique sako rail, not a picatinny. Can anyone here suggest a high quality scope mount for this combo. I called a well known company and the scope mount they recommended would not fir , the height was too low and the sako mount is not a picatinny. any sufggestions would be appreciated
