Sharps rifles are a series of large-bore single-shot rifles, beginning with a design by Christian Sharps in 1848, and ceasing production in 1881. They are renowned for long-range accuracy. By 1874 the rifle was available in a variety of calibers and had been adopted by the armies of a number of nations and was one of the few successful designs to transition to metallic cartridge use.
Reproductions of the Sharps rifle are currently made by different rifle companies and the rifle has become an icon of the Old West due to its use in a number of movies and books in the Western genre.
Sharps' initial rifle was patented September 12, 1848 and manufactured by A. S. Nippes at Mill Creek, (Philadelphia) Pennsylvania, in 1850.
The second model used the Maynard tape primer, and surviving examples are marked Edward Maynard - Patentee 1845. In 1851 the second model was brought to the Robbins & Lawrence Company of Windsor, Vermont where the Model 1851 was developed for mass production. Rollin White of the R&L Co. invented the knife-edge breech block and self-cocking device for the "box-lock" Model 1851. This is referred to as the "First Contract", which was for 10,000 Model 1851 carbines - of which approximately 1,650 were produced by R&L in Windsor.
