History
The Remington Rolling Block rifle is one of the most successful single-shot weapons ever developed. It is a strong and simple action, very reliable, and not prone to be jammed by dirt or rough usage. It was invented by Leonard Geiger during theUnited States Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states ...
and patented in 1863, who (along with his partner, Charles Alger) negotiated a royalty deal with Remington when they put it into production as the so-called "split breech" action late in the war. That design was re-engineered by Joseph Rider in 1865 and called the "Remington System". The first firearm based on it, the Model 1865 Remington Pistol, was offered for sale to the United States Army and Navy in 1866. While the Army turned the design down, the Navy committed to purchase 5000 pistols.
The first rifle based on this design was introduced at the Paris Exposition in 1867 and the United States Navy placed an order for 12,000 rifles. Within a year it had become the standard military rifle of several nations, including Sweden, Norway, and Denmark.
Many earlier percussion rifles and muskets were converted to rolling-block designs in the interim before the development of more modern bolt-action designs.
