What type of firearm utilizes a flint instead of a percussion cap for ignition?

A firearm that utilizes a flint instead of a percussion cap for ignition is known as a flintlock. Flintlock mechanisms operate by striking a piece of flint against a steel frizzen, generating a spark that ignites the gunpowder in the pan, which then travels into the barrel to ignite the main charge. This system was prevalent from the 17th to the early 19th centuries and is significant in the history of firearms due to its advancement over earlier matchlock systems.

In contrast, the other types of firearms mentioned rely on different ignition systems. Caplock or percussion firearms use a percussion cap to ignite the gunpowder, marking a key development in firearm technology. Inline percussion firearms also utilize a similar ignition system but are designed for modern muzzleloading and offer advantages in terms of ease of loading and accuracy. Break-action firearms typically refer to a mechanism for loading, where the barrel is hinged to allow for easy access for loading and unloading, and can be either percussion or flintlock depending on the specific design. The distinction between these systems highlights the evolution of firearm technology over the years.
