Winchester Repeating Arms has produced firearms and ammunition since 1866. The Model 1873 lever-action rifle became widely associated with westward expansion in the United States. The Model 94 lever-action remains in production and is used by hunters and collectors. The bolt-action Model 70, often called the "Rifleman's Rifle," is chambered in a range of hunting calibers and has a long track record for field accuracy. In shotguns, the SX4 semi-automatic and SXP pump-action cover waterfowl, upland, and home-defense applications.
