When should phase 2 clearance be used with a semiautomatic rifle/carbine?

Phase 2 clearance is utilized when phase 1 clearance has failed, indicating that the firearm is experiencing a malfunction that wasn't resolved by the initial remedial action. In this context, semiautomatic rifles and carbines require the shooter to follow a specific series of steps to clear a malfunction efficiently. Phase 1 clearance typically involves a basic response to address a failure to fire, such as attempting to chamber a new round. If this action does not resolve the issue, phase 2 clearance comes into play, focusing on further actions that may involve more in-depth troubleshooting.

In scenarios such as cleaning the rifle or shooting from a prone position or cover, other procedures or considerations apply that do not specifically address malfunction clearance. Therefore, the use of phase 2 clearance is directly tied to the failure of phase 1 to properly clear the malfunction, highlighting its critical role in effective firearms operation and safety practices.
