Answer :
Final answer:
The correct answer is the percussion rifle, which is an example of a caplock muzzleloader. Caplock systems replaced the older flintlock mechanism, presenting a technological advancement in the 19th century. This made firearms more reliable and quicker to fire. Hence the correct option is option 2) Percussion rifle.
Explanation:
Caplock, or percussion lock systems, use a small percussion cap struck by the hammer to ignite the powder, replacing the older flintlock mechanism. This system was a significant technological advancement in firearms during the 19th century, making firearms more reliable and quicker to fire.
Flintlock muskets, the predecessor to the percussion system, used a piece of flint to strike a spark and ignite the powder. Bolt-action shotguns and semi-automatic pistols are much later innovations in firearms technology that use completely different mechanisms for firing.
The percussion rifle represents an important development in the evolution of firearms technology, bridging earlier muzzle-loading mechanisms and the later breech-loading designs. This progression in firearms technology contributed significantly to military tactics and effectiveness on the battlefield.
