What does the Burst setting do on the M16/M4 fire control selector?

• A. Burst mode delivers a 3-round burst on auto-capable models.
• B. Fires a continuous stream while the trigger is pressed.
• C. Fires a single round per trigger pull.
• D. Disables firing.

Answer: (C)

Burst mode controls how many rounds come out with each pull of the trigger. When you set the M16/M4 to Burst, a single trigger squeeze fires a short, fixed number of rounds—typically three—and then the weapon stops firing even if you keep the trigger pressed. You have to release the trigger and pull again to fire another burst. This is different from semi-automatic, which fires one round per trigger pull, and from full-automatic, which continues firing as long as the trigger is held. The burst capability is available only on models designed for it, and on those that aren’t burst-capable the behavior would align with the model’s available fire modes.
