DoubleStar AR Firing Pin

A firing pin is a crucial component of firearms, responsible for striking the primer of a cartridge to ignite the propellant and fire the bullet. It is typically a slender, cylindrical metal rod that is driven forward by the force of a spring or hammer mechanism when the trigger is pulled. The tip of the firing pin makes contact with the primer, causing it to detonate and initiate the firing sequence. Firing pins come in various designs and materials, depending on the type of firearm and its intended use.
