A lever-action is a type of firearm mechanism that uses a lever to load and fire cartridges. When the shooter pulls down on the lever, it opens the action, ejects the spent cartridge, and chambers a new round. This design allows for quick follow-up shots, making it popular among hunters and sport shooters. The Winchester rifle is one of the most famous examples of a lever-action firearm. Its iconic design and reliability have made it a favorite in American history, often associated with the Old West. Lever-action rifles are still used today for various shooting sports and hunting activities.
