The Lee Model 1895 (also known as the Lee Rifle, Model of 1895, caliber 6-mm, Model 1895 Lee Navy, 6mm Lee Navy, Lee Rifle, Model of 1895, etc.) was a straight-pull, cam-action magazine rifle adopted in limited numbers by the U.S. Navy and Marine Corps in 1895 as a first-line infantry rifle. The Navy`s official designation for the Lee Straight-Pull rifle was the "Lee Rifle, Model of 1895, caliber 6-mm". It fired a 6mm (0.236-in. caliber) cartridge, used an early smokeless powder, was semi-rimless, and fired a 135-grain (later 112-grain) jacketed bullet. The 6mm U.S.N. or Lee Navy cartridge was also used in the Navy version of the Colt-Browning Model 1895 machinegun.
