The orientation of a specific component within the AR-15 fire control group dictates the proper function of the semi-automatic firing sequence. This component’s placement ensures correct tension and release, facilitating the hammer’s movement to strike the firing pin. An improperly installed component can lead to malfunctions, including failure to fire, unintentional full-auto fire, or other safety hazards.
Correct component alignment is crucial for safe and reliable firearm operation. This small detail contributes significantly to the weapon’s mechanical precision and predictable performance. Understanding this aspect of the AR-15 mechanism allows for proper maintenance, troubleshooting, and customization, minimizing the risk of mechanical failures. Historically, advancements in firearms technology, including refinements in these small components, have led to improved safety and reliability.
