Lever action is a type of firearm action which uses a lever located around the trigger guard area (often including the trigger guard itself) to load fresh cartridges into the chamber of the barrel when the lever is worked. This contrasts to bolt-action, semi-automatic, or selective-fire weapons. Most lever-action firearms are rifles, but some lever-action shotguns and a few pistols have also been made. One of the most famous lever-action firearms is the Winchester Model 1873 rifle, but many manufacturers—notably Marlin and Savage—also produce lever-action rifles. Mossberg produces the 464 in centerfire .30-30 and rimfire .22. While the term lever-action generally implies a repeating firearm, it is also sometimes (and incorrectly) applied to a variety of single-shot, or falling-block actions that use a lever for cycling, such as the Martini–Henry or the Ruger No. 1.
