My ‘66 DL in 308 came with a same date Leupold M8 4x on it. Inexperienced with fixed powers I was a little skeptical at first and posted the question here and elsewhere if I should swap out for a different optic. Overwhelming response was NO. I have since come to appreciate this mating of rifle and scope very much. You can find these old leupolds on-line, in mint condition, for under 200. Has all the attributes you’re looking for I think. Seems appropriate for the caliber, or you could do the same scope in a 6x.
