The model of 1885 (a modern collector designation; Remington called these the "Remington Magazine Rifle" and did not differentiate between the different versions) was the final iteration of James Paris Lee's bolt action rifle made by Remington. It incorporated a number of improvements from the earlier versions, including a relocated bolt handle, improved bolt head, and a magazine that could now hold cartridges securely without the use of a sliding catch at the nose.
These rifles were made in .45-70 caliber for US use and in .43 Spanish for export sales. The US Navy purchased most of the .45-70 guns that were made, and this particular rifle is one of those Navy guns. By the time these rifles were actually in production, Great Britain had also decided to adopt the Lee system in 1888, which would go through several iterations and ultimately become the iconic SMLE that would be the mainstay of British infantry during the First World War.
