Flintlock rifles are a type of firearm that use a flint mechanism to ignite gunpowder. This design became popular in the 17th century and remained in use until the mid-19th century. The flintlock mechanism consists of a piece of flint that strikes steel, creating a spark that ignites the powder in the firing pan, leading to the discharge of the bullet. These rifles were commonly used by soldiers and hunters during their time, including figures like George Washington and Daniel Boone. Flintlock rifles are known for their historical significance and craftsmanship, often featuring intricate designs and woodwork.
