Lever-action rifles are a type of firearm that uses a lever mechanism to load and fire cartridges. When the shooter operates the lever, it ejects the spent cartridge, chambers a new round, and cocks the hammer, allowing for quick follow-up shots. This design is popular for its ease of use and rapid cycling. These rifles were especially popular in the 19th century and are often associated with the American West. Notable models include the Winchester 1873 and the Henry rifle. Lever-action rifles are still used today for hunting and sport shooting due to their reliability and historical significance.
