I put those on a 30/06 Rem 700 ADL, I bought in 1979 in Minnesota.
They worked real well, and were used often, hunting northern MN south of International Falls, and a Tasco 3 x 9 x 32 scope on top, which fogged and then froze every time you raised it up in front of you eye, and forgot to hold your breathe.
rubbing candle wax on your rear lens solved that problem, I later learned.
a cheap scope was useless at 10 and 20 below...but I was too young and stupid to know that at the time.
wife's family just hunted with open sites and didn't use scopes.
hell in those northern swamps, 50 yds was a long shot... longest shots were down a snow mobile trail...
