Lever-action is a type of firearm action which uses a lever located around the trigger guard area, to load fresh cartridges into the chamber of the barrel when the lever is worked. One of the most famous lever-action firearm is undoubtedly the Winchester rifle, but many manufacturers- notably Marlin and Savage- also produce lever-action rifles. Mossberg produces the 464 in center fire .30-30 and rim fire .22. While the term lever-action generally implies a repeating firearm, it is also sometimes 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.
