Yes the old weavers are a bit clunky. I have had very good service from 2 or 3 . One on a 30-06 1917 Enfield that I hunted first about 1960. A K-6 with a post .
I had it out and fired it a few days ago. Has not changed point of aim ever as far as I can remember.
As mentioned all are not like that .I have cussed several over the years.
