I use to buy mostly K series Weavers when I started in 60s. Shifted to Leupold in 70s. All straight powers. I did buy a few Redfields along the way and have no complaints on any of them. Have some rifle scope combinations that are still together over 50yrs. I did buy a Nikon 6x that was a very good scope and let it go on a rifle. The last new scope I bought was Burris FF 3x9 for my 1895 Mar. The scope was fine but I didn't like the scope on lever the first time in the woods. Took it off and put reciever sight back on.
