The SKS is an Izveshk from 1954 (my birthdate) and it is looking better that I do for the same amount of years.

I don't have a picture of the Marlin model 80 but I actually enjoyed shooting it more than the SKS as my failing eyes have trouble with the SKS sights. I was able to hit the range steel swinging targets at 200 yards with it with regularity. The targets are about a foot across but look like poker chips from 200 yards with iron sights!
