A Leupold VariXIII  1.5-5X 20 mm on my M70...it's light, bright, looks about right. The optics are great and it's just about ideal for our Maine woods hunting.

I have an old Zeiss Zielklein 2.5X that is going to go on a Belgian Mauser I bought from my father in law that I reall like. Especially the German 1 post and horizontal hair. So much so I would convert my Leupold someday when I have the extra $$. It's a bold reticule for larger game hunting.
