Introduced to celebrate the American Centennial Exposition, the Model 1876 earned a reputation as a durable and powerful hunting rifle. Four versions were produced: a barrel "Carbine", a barrel "Express Rifle" with a half-length magazine, a barrel "Sporting Rifle", and a barrel "Musket". Standard rifles had a blued finish while deluxe models were casehardened. Collectors identify a first model with no dust cover, a second model with a dust cover rail fastened by a screw, and a third model with an integral dust cover. Total production was 63,871 including 54 "One of One Thousand" Model 1876s and only seven of the "One of One Hundred" grade.
