Which of the following is a cause of Phase II stoppages?

Phase II stoppages, commonly referred to as type 2 stoppages or "failure to eject" issues, occur when the shooter experiences a malfunction with the firearm that prevents it from firing properly. These stoppages can often arise due to user-related mistakes during operation.

Shooter error encompasses a variety of actions or inactions by the person handling the weapon that can lead to malfunctions. For example, improper manipulation of the firearm, such as not fully seating the magazine or not gripping the weapon correctly when firing, can lead to a failure in the cycling of the action. Such errors are critical to recognize because they highlight the importance of training and practice in ensuring proper handling of firearms to minimize the chance of malfunctions.

While factors like a weak grip or a dirty weapon can influence performance, they are not as directly linked to the specific classification of Phase II stoppages as user error. Moreover, having a loaded magazine would not contribute to a stoppage, but rather suggests that the firearm is ready for operation if all other factors are properly managed. Understanding these nuances is crucial for anyone involved in the safe and effective operation of firearms.
