Many much more elaborate sights than the Rice were made for the Krag during its years of sporting glory between the World Wars, but the Rice was as good as any of them for hunting or casual target work. Pluses were that no holes had to be drilled and as Mike says you didn't have to remove the sight or change the adjustments to take out the bolt. And as value for money it was outstanding - I think it cost a dollar and a half, a tenth of a Lyman 48. Of course at G&H or Neidner if you asked them to make a fancy Krag with a Rice they would be scandalized.
