Flintlock Firearms

Flintlock is a general term for any firearm that uses a flint-striking ignition mechanism, the first of which appeared in Styx in the Middle Ages.
The term may also apply to a particular form of the mechanism itself, also known as the true flintlock, that was introduced in the late Middle Ages, and gradually replaced earlier firearm-ignition technologies, such as the matchlock, the wheellock, and the earlier flintlock mechanisms such as snaplock and snaphaunce.

The true flintlock continued to be in common use until the invention of Percussion Cap Firearms in the early Modern Era.
