In inertia-driven firearms, what occurs when the inertia spring drives the carrier back faster than the barrel and bolt?

Inertia-driven firearms utilize a system where the movement of the bolt and carrier is influenced by inertia. When the inertia spring drives the carrier backward at a speed greater than that of the barrel and bolt, it results in a separation of movement between the components. Specifically, the barrel and bolt do not rearwardly accelerate at the same rate as the carrier due to the damping effect of the inertia spring. This differential motion ultimately causes the barrel and bolt to cease their rearward movement while the carrier continues to move backward. Such mechanics are critical in ensuring that the firearm operates reliably, allowing the extraction and ejection of spent cartridges while preparing the system for the next round to be chambered effectively. Understanding this interaction is key to troubleshooting and maintaining the firearm's functionality.
