What Is AR -15 Trigger? 💡
It refers to the trigger mechanism used in the AR-15 rifle, which is a popular semi-automatic firearm. The AR-15 trigger is a component that, when pulled, initiates the firing sequence, allowing the firearm to discharge a round.
How Does the AR-15 Trigger Works? 🔐
|🤚 Finger on Trigger: The shooter places their index finger on the trigger, preparing to fire the rifle.|
|📜 Take-Up Stage: Initially, the trigger has some slack or take-up. When the shooter begins applying pressure to the trigger, it moves backward slightly.|
|🎯 Second Stage: As the shooter continues to apply pressure, they reach a stopping point or wall. This indicates the transition to the second stage.|
|🎢 Trigger Break: Applying more force, the trigger breaks or releases, allowing the hammer to be released and strike the firing pin.|
|🔨 Firing Pin Strikes Primer: The hammer, released by the trigger, strikes the firing pin, causing it to strike the primer of the chambered round.|
|💥 Ignition: The impact of the firing pin on the primer ignites the primer’s sensitive chemicals, resulting in a small explosion.|
|🔫 Round Fired: The explosion from the primer ignites the gunpowder within the cartridge, propelling the bullet out of the barrel.|
|🔄 Reset: After firing, the shooter releases their finger from the trigger, allowing it to reset to its initial position.|
