The Remington-Rider rolling block became Remington's enduring plains or "buffalo" single shot rifle design. It was probably the most popular rifle used by the old time buffalo (bison) hunters. It evolved from a design patented in 1863 by a Remington employee named Leonard Geiger and was improved over the next three years by Joseph Rider, who was the Remington factory superintendent. By 1866 the Remington-Rider rolling block rifle had evolved. Remington Rolling block single shot rifles were produced throughout the latter decades of the 19th Century and the first decades of the 20th Century.
