I've got optics from across the board: Swarovski, Zeiss, Leupold, Redfield, Nikon & even an old 30+yr old Tasco on my 10-22 that REFUSES to die! (My rangefinder is a Leica 800 I've had for well over a decade) But I'll always admit, day in - day out, Nikon is just about impossible to beat for the $$$!
