firearm technology

Firearm technology involves the design and mechanics of devices that fire projectiles using controlled explosions. Key components include the barrel (guides the projectile), firing mechanism (strikes the primer to ignite the propellant), and magazine or supply (holds ammunition). When the trigger is pulled, the firing pin ignites the primer, igniting the powder inside the cartridge and generating gas pressure. This pressure propels the bullet through the barrel and out of the firearm. Advances include semi-automatic systems that automatically load the next round, and safety features to prevent accidental discharge. Overall, firearm technology combines principles of mechanics, chemistry, and engineering for controlled, repeatable operation.
