Lately most mid caliber rifles come with no sights. When I buy a rifle I take it out and shoot from the hip (literally) into a backstop for a few rounds to make sure they function, then the rifle sits for a year till I get the money together to buy a good scope. Iron sights I can use any time and carry behind my seat without breaking something. Even the budget rifles require the cost of the rifle extra to be able to shoot them with a scope.
