I have had many NC star scopes over the years I know don't laugh long story short is my wife's hunting rifle is a 357 lever action with a 2-7x32 NC Star pistol scope and we zeroed it years back and it is still true today she has taken many deer with the setup only issue we have ever had is it was illuminated and that quit working about 3 years ago the illumination is not required for it to work.
