This is about cheap scopes period, not your leo and swarz and other elite companies. I honestly have not had any failure with any of the simmons scopes I purchased in the last 10 years. Personally I think they are great for my application. I take off my middle class(all I can afford) scopes after the hunt and put on a cheapo simmons for cast boolit RD. Has any one here had any failure of any kind with these latest scopes? I am just curious what others might have found.
