Which bolt position is characterized by the bolt grabbing the round and chambering it after trigger pull?

• A. Open Bolt Position
• B. Closed Bolt Position
• C. Bolt Not Engaged
• D. Firing Bolt

Answer: (C)

The core idea here is how the bolt cycles to chamber a round. When the trigger is pulled, if the bolt isn’t yet engaged with a cartridge, the sear release allows the bolt to move forward and grab a round from the magazine, seating it into the chamber. That moment—the bolt moving forward to chamber the round after trigger release—happens before the cartridge is in a locked, chambered state, so the bolt is described as not engaged with a chambered round at that instant. Once the round is seated, the bolt becomes engaged in the chamber and is ready for firing. In other bolt positions, you’d either have a round already chambered with the bolt forward (closed bolt), the bolt fully to the rear with no round chambered (open bolt), or you’re in the act of firing (firing bolt). None of those precisely describe the step of the bolt moving forward to grab and chamber a round after the trigger is pulled, which is why this state is characterized as not engaged.
