I have plenty of fixed Leupolds of older vintage - their advantage is good eye relief and fairly good lens coatings.
My second choice would be fixed Nikon or Burris - again, good eye relief and fairly good coatings and just a few ounces more than similar Leupolds.
Third would be a fixed Weaver. Micro trac adjustments were brought out in the late 1970’s, so I’d avoid older models. I have two older k6 scopes and they have good eye relief and so so clarity. The Japanese made aluminum bodied scopes must have come out in the 1980’s - on paper they looked good, but had short eye relief. Teenage me had a new steel k4 and the year the aluminum k4 came out quickly bought one, but it wasn’t an improvement and it was quickly sold. A fixed aluminum 15x would be a good varmint/plinking scope.
Tied for fourth would be fixed Redfield and fixed B&L - these aren’t bad, but have eye relief that’s quite short - good for up to 243, one of the creedmoors, or a 270. The B&L is essentially a Bushnell with upgraded lenses - it should have been a good scope, but the eye relief held it back.p
The German brands of this age range have good reputations - at the time, these were at least two or three times the cost of a new Leupold so they were rarely seen in person - you just have to watch out for weird European reticles.
