Multiple Choice

Which of the following describes a double feed malfunction?

A double feed happens when more than one cartridge ends up in the chamber during cycling, so two rounds obstruct the chamber area at once. In this situation, the firearm cannot cycle properly because the bolt is trying to compress and seat two rounds at the same time, creating a solid jam. That’s why the correct description is multiple rounds in the chamber. Understanding the mechanics helps: a semi-automatic firearm relies on feeding a single round from the magazine into the chamber with each cycle. If the top round and the next round are both pushed forward, or the second round wedges behind the first, you’ll end up with two rounds occupying the space designed for one. The result is a tight bind that prevents the bolt from fully closing and stops the gun from firing. To clear it, you would typically lock the bolt to the rear, remove the magazine, and manually remove the rounds from the chamber, then reinsert a magazine and chamber a single round with a proper cycling action, ensuring the firearm is safe before continuing.
